How Postponing Binary Option Expiry Times Can Work in Your ...

No gods, no kings, only NOPE - or divining the future with options flows. [Part 2: A Random Walk and Price Decoherence]

tl;dr -
1) Stock prices move continuously because different market participants end up having different ideas of the future value of a stock.
2) This difference in valuations is part of the reason we have volatility.
3) IV crush happens as a consequence of future possibilities being extinguished at a binary catalyst like earnings very rapidly, as opposed to the normal slow way.
I promise I'm getting to the good parts, but I'm also writing these as a guidebook which I can use later so people never have to talk to me again.
In this part I'm going to start veering a bit into the speculation territory (e.g. ideas I believe or have investigated, but aren't necessary well known) but I'm going to make sure those sections are properly marked as speculative (and you can feel free to ignore/dismiss them). Marked as [Lily's Speculation].
As some commenters have pointed out in prior posts, I do not have formal training in mathematical finance/finance (my background is computer science, discrete math, and biology), so often times I may use terms that I've invented which have analogous/existing terms (e.g. the law of surprise is actually the first law of asset pricing applied to derivatives under risk neutral measure, but I didn't know that until I read the papers later). If I mention something wrong, please do feel free to either PM me (not chat) or post a comment, and we can discuss/I can correct it! As always, buyer beware.
This is the first section also where you do need to be familiar with the topics I've previously discussed, which I'll add links to shortly (my previous posts:

A Random Walk Down Bankruptcy
A lot of us have probably seen the term random walk, maybe in the context of A Random Walk Down Wall Street, which seems like a great book I'll add to my list of things to read once I figure out how to control my ADD. It seems obvious, then, what a random walk means - when something is moving, it basically means that the next move is random. So if my stock price is $1 and I can move in $0.01 increments, if the stock price is truly randomly walking, there should be roughly a 50% chance it moves up in the next second (to $1.01) or down (to $0.99).
If you've traded for more than a hot minute, this concept should seem obvious, because especially on the intraday, it usually isn't clear why price moves the way it does (despite what chartists want to believe, and I'm sure a ton of people in the comments will tell me why fettucini lines and Batman doji tell them things). For a simple example, we can look at SPY's chart from Friday, Oct 16, 2020:

https://preview.redd.it/jgg3kup9dpt51.png?width=1368&format=png&auto=webp&s=bf8e08402ccef20832c96203126b60c23277ccc2
I'm sure again 7 different people can tell me 7 different things about why the chart shape looks the way it does, or how if I delve deeply enough into it I can find out which man I'm going to marry in 2024, but to a rationalist it isn't exactly apparent at why SPY's price declined from 349 to ~348.5 at around 12:30 PM, or why it picked up until about 3 PM and then went into precipitous decline (although I do have theories why it declined EOD, but that's for another post).
An extremely clever or bored reader from my previous posts could say, "Is this the price formation you mentioned in the law of surprise post?" and the answer is yes. If we relate it back to the individual buyer or seller, we can explain the concept of a stock price's random walk as such:
Most market participants have an idea of an asset's true value (an idealized concept of what an asset is actually worth), which they can derive using models or possibly enough brain damage. However, an asset's value at any given time is not worth one value (usually*), but a spectrum of possible values, usually representing what the asset should be worth in the future. A naive way we can represent this without delving into to much math (because let's face it, most of us fucking hate math) is:
Current value of an asset = sum over all (future possible value multiplied by the likelihood of that value)
In actuality, most models aren't that simple, but it does generalize to a ton of more complicated models which you need more than 7th grade math to understand (Black-Scholes, DCF, blah blah blah).
While in many cases the first term - future possible value - is well defined (Tesla is worth exactly $420.69 billion in 2021, and maybe we all can agree on that by looking at car sales and Musk tweets), where it gets more interesting is the second term - the likelihood of that value occurring. [In actuality, the price of a stock for instance is way more complicated, because a stock can be sold at any point in the future (versus in my example, just the value in 2021), and needs to account for all values of Tesla at any given point in the future.]
How do we estimate the second term - the likelihood of that value occurring? For this class, it actually doesn't matter, because the key concept is this idea: even with all market participants having the same information, we do anticipate that every participant will have a slightly different view of future likelihoods. Why is that? There's many reasons. Some participants may undervalue risk (aka WSB FD/yolos) and therefore weight probabilities of gaining lots of money much more heavily than going bankrupt. Some participants may have alternative data which improves their understanding of what the future values should be, therefore letting them see opportunity. Some participants might overvalue liquidity, and just want to GTFO and thereby accept a haircut on their asset's value to quickly unload it (especially in markets with low liquidity). Some participants may just be yoloing and not even know what Fastly does before putting their account all in weekly puts (god bless you).
In the end, it doesn't matter either the why, but the what: because of these diverging interpretations, over time, we can expect the price of an asset to drift from the current value even with no new information added. In most cases, the calculations that market participants use (which I will, as a Lily-ism, call the future expected payoff function, or FEPF) ends up being quite similar in aggregate, and this is why asset prices likely tend to move slightly up and down for no reason (or rather, this is one interpretation of why).
At this point, I expect the 20% of you who know what I'm talking about or have a finance background to say, "Oh but blah blah efficient market hypothesis contradicts random walk blah blah blah" and you're correct, but it also legitimately doesn't matter here. In the long run, stock prices are clearly not a random walk, because a stock's value is obviously tied to the company's fundamentals (knock on wood I don't regret saying this in the 2020s). However, intraday, in the absence of new, public information, it becomes a close enough approximation.
Also, some of you might wonder what happens when the future expected payoff function (FEPF) I mentioned before ends up wildly diverging for a stock between participants. This could happen because all of us try to short Nikola because it's quite obviously a joke (so our FEPF for Nikola could, let's say, be 0), while the 20 or so remaining bagholders at NikolaCorporation decide that their FEPF of Nikola is $10,000,000 a share). One of the interesting things which intuitively makes sense, is for nearly all stocks, the amount of divergence among market participants in their FEPF increases substantially as you get farther into the future.
This intuitively makes sense, even if you've already quit trying to understand what I'm saying. It's quite easy to say, if at 12:51 PM SPY is worth 350.21 that likely at 12:52 PM SPY will be worth 350.10 or 350.30 in all likelihood. Obviously there are cases this doesn't hold, but more likely than not, prices tend to follow each other, and don't gap up/down hard intraday. However, what if I asked you - given SPY is worth 350.21 at 12:51 PM today, what will it be worth in 2022?
Many people will then try to half ass some DD about interest rates and Trump fleeing to Ecuador to value SPY at 150, while others will assume bull markets will continue indefinitely and SPY will obviously be 7000 by then. The truth is -- no one actually knows, because if you did, you wouldn't be reading a reddit post on this at 2 AM in your jammies.
In fact, if you could somehow figure out the FEPF of all market participants at any given time, assuming no new information occurs, you should be able to roughly predict the true value of an asset infinitely far into the future (hint: this doesn't exactly hold, but again don't @ me).
Now if you do have a finance background, I expect gears will have clicked for some of you, and you may see strong analogies between the FEPF divergence I mentioned, and a concept we're all at least partially familiar with - volatility.
Volatility and Price Decoherence ("IV Crush")
Volatility, just like the Greeks, isn't exactly a real thing. Most of us have some familiarity with implied volatility on options, mostly when we get IV crushed the first time and realize we just lost $3000 on Tesla calls.
If we assume that the current price should represent the weighted likelihoods of all future prices (the random walk), volatility implies the following two things:
  1. Volatility reflects the uncertainty of the current price
  2. Volatility reflects the uncertainty of the future price for every point in the future where the asset has value (up to expiry for options)
[Ignore this section if you aren't pedantic] There's obviously more complex mathematics, because I'm sure some of you will argue in the comments that IV doesn't go up monotonically as option expiry date goes longer and longer into the future, and you're correct (this is because asset pricing reflects drift rate and other factors, as well as certain assets like the VIX end up having cost of carry).
Volatility in options is interesting as well, because in actuality, it isn't something that can be exactly computed -- it arises as a plug between the idealized value of an option (the modeled price) and the real, market value of an option (the spot price). Additionally, because the makeup of market participants in an asset's market changes over time, and new information also comes in (thereby increasing likelihood of some possibilities and reducing it for others), volatility does not remain constant over time, either.
Conceptually, volatility also is pretty easy to understand. But what about our friend, IV crush? I'm sure some of you have bought options to play events, the most common one being earnings reports, which happen quarterly for every company due to regulations. For the more savvy, you might know of expected move, which is a calculation that uses the volatility (and therefore price) increase of at-the-money options about a month out to calculate how much the options market forecasts the underlying stock price to move as a response to ER.
Binary Catalyst Events and Price Decoherence
Remember what I said about price formation being a gradual, continuous process? In the face of special circumstances, in particularly binary catalyst events - events where the outcome is one of two choices, good (1) or bad (0) - the gradual part gets thrown out the window. Earnings in particular is a common and notable case of a binary event, because the price will go down (assuming the company did not meet the market's expectations) or up (assuming the company exceeded the market's expectations) (it will rarely stay flat, so I'm not going to address that case).
Earnings especially is interesting, because unlike other catalytic events, they're pre-scheduled (so the whole market expects them at a certain date/time) and usually have publicly released pre-estimations (guidance, analyst predictions). This separates them from other binary catalysts (e.g. FSLY dipping 30% on guidance update) because the market has ample time to anticipate the event, and participants therefore have time to speculate and hedge on the event.
In most binary catalyst events, we see rapid fluctuations in price, usually called a gap up or gap down, which is caused by participants rapidly intaking new information and changing their FEPF accordingly. This is for the most part an anticipated adjustment to the FEPF based on the expectation that earnings is a Very Big Deal (TM), and is the reason why volatility and therefore option premiums increase so dramatically before earnings.
What makes earnings so interesting in particular is the dramatic effect it can have on all market participants FEPF, as opposed to let's say a Trump tweet, or more people dying of coronavirus. In lots of cases, especially the FEPF of the short term (3-6 months) rapidly changes in response to updated guidance about a company, causing large portions of the future possibility spectrum to rapidly and spectacularly go to zero. In an instant, your Tesla 10/30 800Cs go from "some value" to "not worth the electrons they're printed on".
[Lily's Speculation] This phenomena, I like to call price decoherence, mostly as an analogy to quantum mechanical processes which produce similar results (the collapse of a wavefunction on observation). Price decoherence occurs at a widespread but minor scale continuously, which we normally call price formation (and explains portions of the random walk derivation explained above), but hits a special limit in the face of binary catalyst events, as in an instant rapid portions of the future expected payoff function are extinguished, versus a more gradual process which occurs over time (as an option nears expiration).
Price decoherence, mathematically, ends up being a more generalizable case of the phenomenon we all love to hate - IV crush. Price decoherence during earnings collapses the future expected payoff function of a ticker, leading large portions of the option chain to be effectively worthless (IV crush). It has interesting implications, especially in the case of hedged option sellers, our dear Market Makers. This is because given the expectation that they maintain delta-gamma neutral, and now many of the options they have written are now worthless and have 0 delta, what do they now have to do?
They have to unwind.

Apple earnings condor, also expected moves in GOOGL AMZN FB

Apple earnings condor, also expected moves in GOOGL AMZN FB
Obviously a massive day for earnings. The VIX is near 40, and that means expected moves for all stocks have expanded. 7 day expected moves for Apple, Amazon, Microsoft, Alphabet and Facebook are now about 25% more than they were at this time last week, now having to incorporate the election and broader market vol. However... because it's Thursday we get a pretty good sense of the event moves themselves using tomorrow's expiration. Here's how the expected moves for tomorrow's close look for the big 4 reporting tonight:
Amazon / 4.9%
chart
Alphabet / 4.0%
chart
Facebook / 5.3%
chart
Apple / 4.2%
chart

Here's how that expected move translates into the condor in AAPL for tomorrow's expiry. It's weird seeing numbers so small for AAPL post split, is the 10 wide condor too tight? $5 moves don't seem very big but it is a different stock now at 114, the risk-reward is decent for something so binary and getting it as close to 1 to 1 is ideal (if possible).

https://i.redd.it/gh9g4pxo22w51.gif
I think directionally Apple (or any of these really) have set-ups for really decent debit spreads, not for tomorrow, but looking out to Nov 20th. More at optionseye including the Debit Spread chart
Let me know what you all are looking at in the comments.

Free Forex Trading Signals Specifically for Binary Options

Providing Free Forex Trading Signals Specifically for Binary Option Traders
Hello Guys,
I have started providing free forex trading signals specifically for Binary Options Traders since today.
My hit rate is over 65%
These trades will be superbly profitable if the payout is over 100%. Some brokers do offer payouts over 100%
The next question that would come to anyone’s mind who reads this is, why are you giving free signals away if they are so profitable? Well, to be honest, I have a problem. The system I have made for giving me signals is superb, but I just cannot control myself and end up over trading. I over trade and end up blowing my account every single time. This system would be superb for someone who can control their emotions and not over trade. So today I have had enough, and I have decided to offer free trading signals.
So what’s in it for me? The idea is to offer free trading signals to build a large following and then I will move on to a limited number of signals for free and all the signals for paid users. That’s how I plan to make money.
Well, now you must be wondering that I have ranted enough so where’s the proof?
I am attaching the link to my twitter profile where I have posted 5 trades along with the entry and proof that they hit targets. Please note that the expiry of 4 minutes works out best for binary options on my trading signals.
Let me know what you guys think. If you truly feel it’s legit then please spread the word.
Thank YouTwitter Posts

I made Gullveig - a distributed infra and service monitoring platform

TL;DR; I have too much time on my hands, apparently.
I know there are a lot of infra monitoring systems out there, but to be perfectly honest, I was not entirely happy with any of them, for a number of reasons - moral age (Nagios is old enough to drive), user interface (Nagios, you again?), resource use (Netdata - OOME much?), deployment options, simplicity, so on, so forth. One of the main reasons though - I really do hate to sleep at night.
A few months ago I set out to create a monitoring system of my own, with somewhat modern interface, as simple and lightweight as possible, and as simple to deploy as possible.
Built in Python, no external dependencies (even database, technically!), minimal and with fairly well designed user interface. System requirements? A potato could probably run every part of this no problem.

Architecture

There are three main components - reporting server, web UI server and reporting agents. Agents send reports about service health, metrics and "metadata" to reporting server. Reporting server saves all that in sqlite3 database. Web UI server reads the database directly and presents the data in a web UI.
Reporting server also does alerting - when agents report some service failure, resource usage issues etc.
Agents also report raw metadata to the server - it can be quite literally anything you like. For example, there is a default module for facter - it will detect presence of facter CLI, fetch all the output and send it to reporting server. From there it is available in the web UI.

DIY more THINGS111!

There are a few basic builtin modules to monitor basic health indicators.
What is probably more important - you can create your own modules in basically any language/platform that can expose JSON in the reporting format expected by the agent.
Want to monitor HTTP resources? Ports? Whatever? As long as you can somehow programmatically get that info, you absolutely can feed it to Gullveig. Repo has an example on how to do this.

Is my stuff working?

Server will automatically check "status" items reported by agents and email you aggregated alerts once something breaks.
If an agents is away for longer than T amount of time - server will automatically mark all services on that server as unknown, and send you an email.
Who watches the watcher?
It is entirely possible for reporting server to die/become unreachable for some reason. If agent is not able to talk to server for T amount of time, it will send you a polite email asking you to kindly fix your stuff.
Once the server is back up, it will be clever enough to not spam you with all services appearing offline because of reporting expiry - it will instead wait for 10 minutes for agents to reconnect and state their current status.

Security

Mandatory TLS for everything, server verification using a kind of certificate pinning, agent authentication using pre-shared keys. Web users - JWT, crypt, the works.

Stability

It works for me. It might or might not work for you. I currently have about a dozen or so agents running with a separate VM reporting server, web ui and agent to monitor itself - all working just fine in a VM with a single core and 256MB RAM.

Where to next?

Right now, there is only a basic set of resource reporting modules. I have quite a few more reporting on all kinds of things (powerdns, postfix, dovecot, fail2ban, etc) - but they are all kind of whack and will need to be rewritten before they can be published.
I would also want to create a "micro-agent" at some point - probably native binary (most likely in C or C++) that is super-lightweight and could be deployed as part of Docker application images, and would report only specific state of those images. Current agent can do that too, but it is not exactly designed to do that.
Yeah.
Source, installation guide etc available on GitHub
Mandatory hard to understand screenshot of the web UI.

Setting up a domain controller using SAMBA 4 on Ubuntu 20.04 with both IPv4 and IPv6 support

(Note: this borrows heavily from https://github.com/thctlo/samba4/blob/mastefull-howto-Ubuntu18.04-samba-AD_DC.txt)
Prerequisites:
  1. Create your Ubuntu 20.04 server system. The details vary depending on what type of host it is. You’ll need to give it a static IP address and as such set up routing. Here’s my /etc/netplan/10-lxc.yaml file in case you’re using LXC:
    network: version: 2 ethernets: eth0: dhcp4: false dhcp6: false addresses: [10.0.0.2/16] gateway4: 10.0.0.1 nameservers: search: - example.com addresses: - 8.8.8.8 
    DHCP6 will need to be set to true if you set your router to provide DHCP6 for IPv6 addresses otherwise it can be set to false and your host will use router advertisements to configure itself. (IPv6 is wonderfully easy!)
    Set the timezone. If using an installer without a GUI you'll need to do this manually, try this:
    timedatectl set-timezone America/New_York 
    1.1 If using LXC, make sure your container is privileged. From the host, type something like:
    lxc stop dc1 sudo lxc config edit dc1 
    Add the following under, and indented to show it's a child of, 'config:'
    raw.lxc: |- lxc.cap.drop = lxc.cap.drop = sys_module mac_admin mac_override security.privileged: "true" 
    It's a YAML file so make sure the indenting is followed as above. These are necessary to make domain provisioning and NTP work.
    Restart and presumably go back in using these commands:
    lxc start dc1 lxc shell dc1 
  2. Set the name – set the shortname using hostnamectl
    hostnamectl set-hostname dc1 
    and edit /etc/hosts so that the first line looks something like this:
    127.0.1.1 dc1.example.com dc1 
  3. Set up a user with sudo permissions to administer the machine. You don’t want to be logged in as root most of the time, and most of the time you don’t even need to use ‘sudo’ for this.
  4. Install openssh-server
    apt-get install openssh-server 
    If you want, you can continue the rest of this remotely from the login you created.
  5. Install SAMBA
    apt install samba winbind libnss-winbind libpam-winbind ntp bind9 binutils ldb-tools krb5-user 
    At this stage you will probably be asked for your Kerberos settings. IMPORTANT: TYPE THE KERBEROS DOMAIN (EXAMPLE.ORG) IN UPPERCASE. Any other questions you should be able to guess the answers for or they may be obvious anyway.
    systemctl disable nmbd smbd winbind systemctl stop nmbd smbd winbind systemctl unmask samba-ad-dc systemctl enable samba-ad-dc 
  6. Set up NTP
    install -d /valib/samba/ntp_signd -m 750 -o root -g ntp cat << EOF >> /etc/ntp.conf # ###### Needed for Samba 4 ###### # extra info, in the restrict -4 or -6 added mssntp. # Location of the samba ntp_signed directory ntpsigndsocket /valib/samba/ntp_signd # EOF sed -i 's/restrict -4 default kod notrap nomodify nopeer noquery limited/restrict -4 default kod notrap nomodify nopeer noquery limited mssntp/g' /etc/ntp.conf sed -i 's/restrict -6 default kod notrap nomodify nopeer noquery limited/restrict -6 default kod notrap nomodify nopeer noquery limited mssntp/g' /etc/ntp.conf systemctl restart ntp systemctl status ntp ntpq -p 
    Some of the above may show error messages under LXC, if so verify you did 1.1 above. If you still get messages, don't panic.
  7. Tweak Kerberos
    All we really need is the domain part for Kerberos, so:
    cd /etc sudo mv krb5.conf krb5.conf.ORG sudo head -n2 krb5.conf.ORG | tee krb5.conf 
    You may also want to edit the krb5.conf file and add these lines to the end to maximize compatibility with other Kerberos implementations:
    default_tgs_enctypes = aes256-cts-hmac-sha1-96 aes128-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5 default_tkt_enctypes = aes256-cts-hmac-sha1-96 aes128-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5 permitted_enctypes = aes256-cts-hmac-sha1-96 aes128-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5 
  8. Set up Samba
    Clear the cobwebs
    rm /valib/samba/*.tdb rm /vacache/samba/*.tdb rm /vacache/samba/browse.dat mv /etc/samba/smb.conf /etc/samba/smb.conf.ORIG 
  9. Create the domain
    If you're using LXC, and you didn't set it up as a privileged container (see 1.1), this is where that will go wrong. So recheck you did 1.1 properly. if you get an error message.
    samba-tool domain provision --use-rfc2307 --realm=EXAMPLE.COM --domain=EXAMPLE --dns-backend=BIND9_DLZ 
    On my system at least this generated a lot of garbage debugging type output but it did end up creating the domain. It will give you a virtually unusable Administrator account password, don't worry we're going to change it. But there's a couple of things we'll do before that.
  10. Set up BIND
    Edit /etc/bind/named.conf.options, to look something like this:
    options { forwarders { 8.8.8.8; }; dnssec-validation auto; listen-on-v6 { any; } notify no; empty-zones-enable: no; tkey-gssapi-keytab "/valib/samba/bind-dns/dns.keytab"; allow-transfer {10.0.0.2;}; } 
    Edit /etc/bind/named.conf.local, and add the line:
    include "/valib/samba/bind-dns/named.conf"; 
    Edit /valib/samba/bind-dns/named.conf, and uncomment out the last entry (yes, I know you're running a more recent version of BIND, that DLL works with it, trust me.)
    Restart BIND
    systemctl restart named 
    Confirm it works - use dig (install it using apt-get install bind9-dnsutils if it wasn't installed already)
    dig @10.0.0.2 www.google.com 
    Finally point this VM to its own DNS server. Edit /etc/netplan/ and change 8.8.8.8 there to 10.0.0.2 and reboot.
  11. Make the administrator account usable
    You probably want to set a password on the latter you'll remember. To do this, use this command:
    sudo samba-tool user setpassword Administrator 
    That's a helpful command to know anyway - anyone with root access to the DC can set passwords here too. If you get a complexity error, you can disable that check using this command do it again:
    sudo samba-tool domain passwordsettings set --complexity=off 
    You can test this all works using:
    kinit Administrator 
    If your password is accepted, not only did it all work, but you're now logged in and can stop using sudo with most SAMBA commands. If you add -k yes to the end of any samba-tool command it will accept you as authorized.
  12. Add a reverse DNS zone and set up DHCP.
    samba-tool dns zonecreate dc1.example.com 0.10.in-addr.arpa -k yes 
    For DHCP I'm going to offer three choices of how to set up DHCP in this environment: use your router's implementation, put one here, and put one here that does DNS updates.
    12.1 Your router
    If you're going to use your router's, you're all set. If you need to set up IP addresses for specific devices, set up the router to give them out (or just disable DHCP on your device itself and set the IP manually, outside of the range your DHCP server issues them), and, if you're not adding them to the domain, add DNS entries like this:
    samba-tool dns add dc1.example.com example.com mypc A 10.0.0.3 -k yes samba-tool dns add dc1.example.com 0.10.in-addr.arpa 3.0 PTR mypc.example.com -k yes 
    Devices that are added to the domain will have their DNS entries managed by SAMBA itself, you don't have to worry about them. If you add a static IP for a host and add DNS for it, you'll need to delete the DNS entries if you then decide to add it to your Active Directory domain.
    12.2 Local ISC DHCP Server
    The second option, running ISC DHCP, is mostly just as easy, it has some advantages that you can log activity and easily see, for example, what each device identified itself as by checking the logs. Again, just use samba-tool as in 12.1 to update IP addresses for static devices that haven't been joined to the network.
    Install isc-dhcp-server using:
    sudo apt-get install isc-dhcp-server 
    Then edit your /etc/dhcp/dhcpd.conf to look something like this:
    authoritative; ddns-update-style none; option subnet-mask 255.255.0.0; option broadcast-address 10.0.255.255; option time-offset 0; option routers 10.0.0.1; option domain-name "example.com"; option domain-name-servers 10.0.0.2; option netbios-name-servers 10.0.0.2; option ntp-servers 10.0.0.2; subnet 10.0.0.0 netmask 255.255.0.0 { range 10.0.1.1 10.0.127.255; default-lease-time -1; max-lease-time -1; } host mypc { hardware ethernet 40:50:60:70:80:90; fixed-address 10.0.0.3; option host-name "mypc"; } 
    "mypc" is an example of a static address, you can add as many host entries as you want.
    Finally, restart DHCP
    systemctl restart isc-dhcp-server 
    12.3 Local ISC Server with DNS updates
    This is what every lazy system administrator wants, and to be fair it can be helpful as long as you have full control over your own network. I cover some of the issues in my preview article. But it's dangerous - essentially you're giving any device that has access to your network authorization to add host records to your DNS server that point at it - at least, as long as it's for the DHCP IPv4 address they've been given. So a malicious entity could, for example, override "login.example.com" and point it at their server, which might be a problem if people go to http://login.example.com whenever they need to enter passwords to access secured content on your system. If nothing else it'd be easy to do a DoS attack. For anything other than a home network or a small office, you shouldn't do this. At all. But if it's your own network, and you administer it, and you monitor what gets plugged into it, then it can save some headaches.
    Given that usage profile, I'm going to make it slightly more insecure than Samba recommends, because Samba's recommended solution... doesn't work. The people who put it together are OK with it not working because in their view it doesn't break anything they themselves need, but it does break IPv6 and certain roaming scenarios, and it does result in error messages that you're going to forget the meaning of and implications of if you don't add something to your domain for a while.
    So here's the solution:
    Do everything in 12.2, but add the following lines to the end of /etc/dhcp/dhcpd.conf:
    on commit { set noname = concat("dhcp-", binary-to-ascii(10, 8, "-", leased-address)); set ClientIP = binary-to-ascii(10, 8, ".", leased-address); set ClientDHCID = concat ( suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,1,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,2,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,3,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,4,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,5,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,6,1))),2) ); set ClientName = pick-first-value(option host-name, config-option-host-name, client-name, noname); log(concat("Commit: IP: ", ClientIP, " DHCID: ", ClientDHCID, " Name: ", ClientName)); execute("/uslocal/bin/dhcp-dyndns.sh", "add", ClientIP, ClientDHCID, ClientName); } on release { set ClientIP = binary-to-ascii(10, 8, ".", leased-address); set ClientDHCID = concat ( suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,1,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,2,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,3,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,4,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,5,1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,6,1))),2) ); log(concat("Release: IP: ", ClientIP)); execute("/uslocal/bin/dhcp-dyndns.sh", "delete", ClientIP, ClientDHCID); } on expiry { set ClientIP = binary-to-ascii(10, 8, ".", leased-address); log(concat("Expired: IP: ", ClientIP)); execute("/uslocal/bin/dhcp-dyndns.sh", "delete", ClientIP, "", "0"); } 
    Now go to Samba's Wiki and copy their script to /uslocal/bin/dhcp-dyndns.sh, and make it executable:
    sudo cp dhcp-dyndns.sh /uslocal/bin/ sudo chmod a+x /uslocal/bin/dhcp-dyndns.sh 
    Set up the dhcpduser:
    samba-tool user create dhcpduser --description="Unprivileged user for TSIG-GSSAPI DNS updates via ISC DHCP server" --random-password -k yes samba-tool user setexpiry dhcpduser --noexpiry -k yes samba-tool group addmembers DnsAdmins dhcpduser -k yes sudo samba-tool domain exportkeytab [email protected] /etc/dhcpduser.keytab sudo chown dhcpd.root /etc/dhcpduser.keytab sudo chmod 400 /etc/dhcpduser.keytab 
    Allow domain hosts (computers added to the domain) to manage their own DNS entries (but alas this command also means they can manage DNS in general):
    samba-tool dsacl set -k yes -H ldap://dc1.example.com --objectdn=CN=MicrosoftDNS,DC=DomainDnsZones,DC=example,DC=com "--sddl=(A;CI;RPWPCRCCDCLCLORCWOWDSDDTSW;;;DC)" 
    If you don't want to do the last bit, your options are limited. My advice is ask yourself why you don't like the idea, because your reasons almost certainly can be expanded to the entire concept of allowing DHCP to add DNS entries based upon self identified hosts. Consider instead doing 11.1 or 11.2.
And that's it. You can test everything's working by adding new sites to the domain. For Windows clients, Microsoft has the documentation. For Ubuntu, well, that's my next article.

Configuring strategy tester for binary options?

Hi! I am hoping someone could lend some advice re how to configure the strategy tester to work with binary options style trading.
In case you're not familiar with binary options, a few notes:
- There is no stop loss, take profit
- There are no spreads/commissions
- I must set an expiry time in minutes or candles
- Simply, if I go "long" (called a CALL) and the expiry price > strike price, that's a win (and < would be a loss); if I go "short" (called a PUT) AND the expiry price < strike price, that's a win (and > would be a loss). Also I could "Push", meaning the strike price = the expiry price. These should be disregarded from the calculations as there is no loss or gain of $.
- As such, I just need a W/L/P (P being 'Push', meaning strike price = expiry price)
Thanks! Welcome any advice. 😀

Binary Options Review; Best Binary Options Brokers
We have compared the best regulated binary options brokers and platforms in May 2020 and created this top list. Every binary options company here has been personally reviewed by us to help you find the best binary options platform for both beginners and experts. The broker comparison list below shows which binary trading sites came out on top based on different criteria.
You can put different trading signals into consideration such as using payout (maximum returns), minimum deposit, bonus offers, or if the operator is regulated or not. You can also read full reviews of each broker, helping you make the best choice. This review is to ensure traders don't lose money in their trading account.
How to Compare Brokers and Platforms
In order to trade binary options, you need to engage the services of a binary options broker that accepts clients from your country e.g. check US trade requirements if you are in the United States. Here at bitcoinbinaryoptionsreview.com, we have provided all the best comparison factors that will help you select which trading broker to open an account with. We have also looked at our most popular or frequently asked questions, and have noted that these are important factors when traders are comparing different brokers:
  1. What is the Minimum Deposit? (These range from $5 or $10 up to $250)
  2. Are they regulated or licensed, and with which regulator?
  3. Can I open a Demo Account?
  4. Is there a signals service, and is it free?
  5. Can I trade on my mobile phone and is there a mobile app?
  6. Is there a Bonus available for new trader accounts? What are the Terms and
  7. conditions?
  8. Who has the best binary trading platform? Do you need high detail charts with technical analysis indicators?
  9. Which broker has the best asset lists? Do they offer forex, cryptocurrency, commodities, indices, and stocks – and how many of each?
  10. Which broker has the largest range of expiry times (30 seconds, 60 seconds, end of the day, long term, etc?)
  11. How much is the minimum trade size or amount?
  12. What types of options are available? (Touch, Ladder, Boundary, Pairs, etc)
  13. Additional Tools – Like Early closure or Metatrader 4 (Mt4) plugin or integration
  14. Do they operate a Robot or offer automated trading software?
  15. What is Customer Service like? Do they offer telephone, email and live chat customer support – and in which countries? Do they list direct contact details?
  16. Who has the best payouts or maximum returns? Check the markets you will trade.
The Regulated Binary Brokers
Regulation and licensing is a key factor when judging the best broker. Unregulated brokers are not always scams, or untrustworthy, but it does mean a trader must do more ‘due diligence’ before trading with them. A regulated broker is the safest option.
Regulators - Leading regulatory bodies include:
  • CySec – The Cyprus Securities and Exchange Commission (Cyprus and the EU)
  • FCA – Financial Conduct Authority (UK)
  • CFTC – Commodity Futures Trading Commission (US)
  • FSB – Financial Services Board (South Africa)
  • ASIC – Australia Securities and Investment Commission
There are other regulators in addition to the above, and in some cases, brokers will be regulated by more than one organization. This is becoming more common in Europe where binary options are coming under increased scrutiny. Reputable, premier brands will have regulation of some sort.
Regulation is there to protect traders, to ensure their money is correctly held and to give them a path to take in the event of a dispute. It should therefore be an important consideration when choosing a trading partner.
Bonuses - Both sign up bonuses and demo accounts are used to attract new clients. Bonuses are often a deposit match, a one-off payment, or risk-free trade. Whatever the form of a bonus, there are terms and conditions that need to be read.
It is worth taking the time to understand those terms before signing up or clicking accept on a bonus offer. If the terms are not to your liking then the bonus loses any attraction and that broker may not be the best choice. Some bonus terms tie in your initial deposit too. It is worth reading T&Cs before agreeing to any bonus, and worth noting that many brokers will give you the option to ‘opt-out’ of taking a bonus.
Using a bonus effectively is harder than it sounds. If considering taking up one of these offers, think about whether, and how, it might affect your trading. One common issue is that turnover requirements within the terms, often cause traders to ‘over-trade’. If the bonus does not suit you, turn it down.
How to Find the Right Broker
But how do you find a good broker? Well, that’s where BitcoinBinaryOptionsReview.com comes in. We assess and evaluate binary options brokers so that traders know exactly what to expect when signing up with them. Our financial experts have more than 20 years of experience in the financial business and have reviewed dozens of brokers.

Ambrosia and Registration

Now that Ambrosia is gone, new registrations are no longer possible, and due to their expiring codes, using legitimate license keys has become difficult. We may hope to see a few of their games revived in the future but at present, only the original releases are available. Perhaps this case study on Ambrosia's registration algorithms will be useful to some.

The Old System

In their earliest days, ASW didn't require registration, but they eventually began locking core features away behind codes. All of their classic titles use the original algorithm by Andrew Welch.
Given a licensee name, number of copies, and game name, the code generator runs through two loops. The first loop iterates over each letter of the capitalized licensee name, adding the ASCII representation of that letter with the number of copies and then rotating the resulting bits. The second loop repeats that operation, only using the game's name instead of the license holder's name.
Beginning with Mars Rising, later games added a step to these loops: XOR the current code with the common hex string $DEADBEEF. However, the rest of the algorithm remained essentially unchanged.
The resulting 32 bits are converted into a text registration code by adding the ASCII offset of $41 to each hex digit. This maps the 32-bit string into 8 characters, but due to the limit of a hex digit to only encode 16 values, codes only contain letters from the first 16 of the alphabet.
The following chart shows an example using a well-known hacked code for Slithereens.
 Iteration 1 ('A' in ANONYMOUS) Name: Anonymous Code = $0 + $41 Number: 100 (hex: $64) -> << 6 ... -> Code = $FD53 FFA0 Game: Slithereens + $64 ^ $DEAD BEEF >> 1 Add $41 to each digit: Registration -> $41 + $F = $50 = P -> Reverse string -> ------------ $41 + $D = $4E = N | AKPPDFNP | ... ------------ 
Here is a Python implementation of the v1 system: aswreg_v1.py
Once you have the bitstring module installed via sudo pip install bitstring, you can test the output yourself with python aswreg_v1.py "Anonymous" 100 "Slithereens".

The New System

As Ambrosia's Matt Slot explains, the old system continued to allow a lot of piracy, so in the early 2000's they decided to switch to a more challenging registration system. This new method was based on polynomial hashing and included a timestamp so that codes could be expired and renewed. Ambrosia now had better control over code distribution, but they assumed their renewal server would never be shut down...
They also took more aggressive steps to reduce key sharing. The registration app checks against a list of blacklisted codes, and if found to be using one, the number of licenses is internally perturbed so that subsequent calculations fail. To combat tampering, your own information can get locally blacklisted in a similar manner if too many failed attempts occur, at least until the license file is deleted. Furthermore, the app attempts to verify the system time via a remote time server to minimize registration by changing the computer's clock.
You can disable the internet connection, set the clock back, and enter codes. There's also a renewal bot for EV: Nova. But let us look at the algorithm more closely.

64-bit Codes

The first noticeable difference is that registration codes in v2 are now 12 digits, containing both letters and numbers. This is due to a move from a 32-bit internal code to a 64-bit one. Rather than add an ASCII offset to hex digits, every letter or number in a new registration code has a direct mapping to a chunk of 5 bits. Using 5 bits per digit supports up to 32 values, or almost all letters of the alphabet and digits up to 9 (O, I, 0, and 1 were excluded given their visual similarities).
The resulting 64 bits (really only 60 because the upper 4 are unused: 12 digits * 5 bits each = 60) are a combination of two other hashes XOR'd together. This is a notable change from v1 because it only used the registration code to verify against the hashing algorithm. Only the licensee name, number of copies, and game name were really used. In v2, the registration code is itself a hash which contains important information like a code's timestamp.

Two Hashes

To extract such information from the registration code, we must reverse the XOR operation and split out the two hashes which were combined. Fortunately, XOR is reversible, and we can compute one of the hashes. The first hash, which I'll call the userkey, is actually quite similar to v1's algorithm. It loops through the licensee name, adding the ASCII value, number of copies, and shifting bits. This is repeated with the game name. An important change is including multiplication by a factor based on the string size.
The second hash, which I'll call the basekey, is the secret sauce of v2; it's what you pay Ambrosia to generate when registering a product. It is not computed by the registration app, but there are several properties by which it must be validated.
The chart below visualizes the relationships among the various hashes, using the well-known "Barbara Kloeppel" code for EV: Nova.
 TEXTCODE: ------------------ | L4B5-9HJ5-P3NB | ------------------ HASH1 (userkey): | calculated from licensee name, | copies, and game name BINCODE: ---------------------- 5 bits per character, /-> | 0x0902f8932acce305 | plus factors & rotation / ---------------------- ---------------------- / | 0x0008ecc1c2ee5e00 | <-- XOR ---------------------- \ \ ---------------------- \-> | 0x090a1452e822bd05 | ---------------------- HASH2 (basekey): generated by Ambrosia, extracted via XOR 

The Basekey

The basekey is where we must handle timestamps and several validation checks. Consider the binary representation of the sample 0x090a1452e822bd05:
binary basekey (above) and indices for reference (below): 0000 1001 0000 1010 0001 0100 0101 0010 1110 1000 0010 0010 1011 1101 0000 0101 b0 b3 b7 b11 b15 b19 b23 b27 b31 b35 b39 b43 b47 b51 b55 b59 b63 

Timestamps

Timestamp are encoded as a single byte comprised of bits indexed at b56,51,42,37,28,23,14,9 from the basekey. In this example, the timestamp is 01100010 or 0x62 or 98.
The timestamp represents the number of fortnights that have passed since Christmas Day, 2000 Eastern time, modulo 256 to fit in one byte. For example, 98 fortnights places the code at approximately October 2004.
Stored as a single byte, there are 256 unique timestamps. This is 512 weeks or about 10 years. Yes, this means that a code's validity rotates approximately once every decade.
After the code's timestamp is read, it is subtracted from the current timestamp (generated from the system clock or network time server if available). The difference must be less than 2, so codes are valid for 4 weeks or about a month at a time.
Of note, Pillars of Garendall has a bug in which the modulo is not taken correctly, so the timestamp corresponding to 0xFF is valid without expiry.

Validity Check

The last three bits, b60-63, contain the sum of all other 3-bit chunks in the basekey, modulo 7. Without the correct number in these bits, the result will be considered invalid.
To this point, we have covered sufficient material to renew licenses. The timestamp can be changed, the last three bits updated, the result XOR'd with the userkey, and finally, the code converted from binary to text.

Factors for Basekey Generation

I was next curious about code generation. For the purposes of this write-up, I have not fully reverse engineered the basekey, only duplicated the aspects which are used for validation. This yields functional keys, just not genuine ones. If the authors of the EV: Nova renewal bot have fully reversed the algorithm, perhaps they will one day share the steps to genuine basekey creation.
One aspect validated by the registration app is that the licensee name, number, and game name can be modified to yield a set of base factors. These are then multiplied by some number and written into the basekey. We do not need the whole algorithm; we simply must check that the corresponding regions in the basekey are multiples of the appropriate factors.
The regions of note in the basekey are f1 = b5-9,47-51,33-37,19-23, f2 = b43-47,29-33,15-19,57-61, and f3 = b24-28,10-14,52-56,38-42. The top 5 bits and f3 are never actually checked, so they can be ignored.
Considering f1 and f2, the values in the sample basekey are 0x25DA and 0x1500, respectively. The base factors are 0x26 and 0x1C, which are multiples by 0xFF and 0xC0, respectively.
Rather than analyze the code in detail, I wrote a small script to translate over the disassembled PPC to Python wholesale. It is sufficient for generating keys to EV: Nova, using the perfectly-valid multiple of 1x, but I have found it fails for other v2 products.

Scripts

Here is a Python implementation for v2: aswreg_v2.py and aswreg_v2core.py
With bitstring installed, you can renew codes like python aswreg_v2.py renew "L4B5-9HJ5-P3NB" "Barbara Kloeppel" 1 "EV Nova" (just sample syntax, blacklisted codes will still fail in the app). There's also a function to check a code's timestamp with date or create a new license with generate.
As earlier cautioned, generating basekeys relies on code copied from disassembled PPC and will likely not work outside EV: Nova. In my tests with other v2 products, all essential parts of the algorithm remain the same, even the regions of the basekey which are checked as multiples of the factors. What differs is the actual calculation of base factors. Recall that these keys were created by Ambrosia outside the local registration system, so the only options are to copy the necessary chunks of code to make passable factors for each product or to fully reverse engineer the basekey algorithm. I've no doubt the factors are an easy computation once you know the algorithm, but code generation becomes less critical when renewal is an option for other games. I leave it to the authors of the Zeus renewal bot if they know how to find these factors more generally.
To renew codes for other games, keep in mind the name must be correct. For instance, Pillars of Garendall is called "Garendall" internally. You can find a game's name by typing a gibberish license in the registration app and seeing what file is created in Preferences. It should be of the form License.
Finally, a couple disclaimers: I have only tested with a handful of keys, so my interpretations and implementations may not be completely correct. YMMV. Furthermore, these code snippets are posted as an interesting case study about how a defunct company once chose to combat software piracy, not to promote piracy. Had Ambrosia remained operational, I'm sure we would have seen a v3 registration system or a move to online-based play as so many other games are doing today, but I hope this has been helpful for those who still wish to revisit their favorite Ambrosia classics.

New DAPP for TRON, trustless binary options

We are halfway through development for a new trustless dapp on the TRON blockchain. The dapp supports binary options trading for a selection of markets with up to 85% payout for winning trades. We use a trustless on-chain custom TRON oracle for connecting to the price API from Kaiko. We also have more crypto based social betting and a few automated trading bots which connect to polonidex for algorithmic trend trading (TRX/JST, TRX/USDT)
The native currency is USDT-TRON and trade expiries range from 10 seconds to 1 hour thanks to the TRON 4.0 upgrade cutting block times down to a few seconds. Currently developing the UI and later creating a non-web3.0 version so you can trade without a dapp browser like TRONlink. This uses Burner Wallet which is in-browser to sign txs on the platforms smart contract wallet/in-app balance.
Let us know what you think and if you have any questions! If you know about binary options and the bad reputation they have, this solves all the fraud and price manipulation thanks to the blockchain. A real killer app in my opinion. We are all very proud to unveil it when it’s complete and will be releasing thousands of dollars of free bet tokens via Airdrop (with a minimum wager requirement of course) so everyone can get involved and see what it’s all about.

What Your Customers Really Think About Your Binary Options Trading?

If you are taking into account most binary options traders, you see for advice that will auspices taking place taking place you make as much of a profit as attainable, but the source of that advice may or may not be beneficial to you. This is because in many cases, the advice you'taking into account reference to monster unchangeable is benefiting somebody else even more. The biggest error made by most traders is believing that all of the advice unlimited by the broker they are full of cartoon when is intended to gain the trader.

How Brokers Make Their Money

Koinpro: Double Up Contract

Koinpro may be a new multi exchange but the developers and overall team pulling the strings on the platform are a savvy lot and experienced and technical know-how to handle the crypto market. With a wide variety of contracts and the ability to trade CFDs using Bitcoin, Koinpro is rapidly becoming a very popular and much-needed futures exchange.One of the main highlights of its features is the Double Up Double Up is more of a feature than a strategy, although you could refer to it as either a feature or a strategy. Until recently, it was alien to the Binary Options industry. Even, at this point, it is only available on a select number of enterprising brokers. ‘Double Up’ is exactly what the name suggests, doubling up your current position. The tool allows a trader to double the investment with the potential resultant effect of doubling the profits from a position at expiration of the contract. The Double Up tool, can therefore be seen as a tool that permits extensibility of your current trade like the “Extend/Rollover” and “Close Now” tools offered by brokers. How does Double Up Work in Binary Options? In general, to use the tool, you should be holding an in-the-money option, with decent time left before expiry, and then you can click on the double up feature (which is often a clickable tab selection on the Broker’s trading platform). By clicking on the feature, you double the potential liability and profit of your current position. Therefore, if you are in the clear when the contract expires, you will have double your initial profits, while the opposite is the case if the position ends out of the money. Nature of Double Up in Binary Options The feature is only available on the platforms of select brokers An option must be ‘in the money’ before the tool can be used Double Up can only be used at a certain point (usually within 5 and 10 minutes) prior to the contract’s expiration A Double Up position is opened at the market rate as at the time the tool is used. Hence, you could make double wins, double losses, or have contrasting results for the original contract and the newer double up contract. Like several innovative features in the financial markets, the Double Up tool may be a blessing or a curse depending on when and how it is used. This is because, while it is marketed as a profit-boosting tool, it can also be a loss-compounding tool.

Tips to Find the Best Binary Options Brokers

With the potential of earning big money, binary options trading has removed in a big way all around the globe. From a number of binary options brokers in 2008, we have about hundreds of these available currently. You will be entrusting your cash to a broker to keep on the trade. Hence, it is very important that you identify the best binary options brokers from the other small and unreliable ones.
The trading of Binary Options first commenced in 2008 at the Chicago Board of Exchange. Such as the name suggests, Binary Options, are derivative contracts with only two possible outcomes at the expiry of the contract i.e. you receive cash/ asset if the contract is'in the amount of money'or nothing otherwise. For instance, suppose you buy a phone option of ABC Ltd.' s share at a strike price of $30 and a binary payoff of $300 binary options brokers. If the stock price is above $30, your contract is'in the amount of money '. By'in the amount of money'contract, we mean that you are in a gain situation as you can buy the stock for the strike price of $30 and sell it at an increased price (the current price) and produce a profit. In this scenario, in a binary option contract, you receive a fixed binary payoff of $300. In most other scenario, you receive nothing and lose the purchase price of the contract. The underlying asset can be stocks, indices, commodities and currencies. Making consistent profits out of trading in binary options depends upon the accuracy with which you may predict asset movements over the word of the contract.
Following are some important strategies for narrowing down your search to the best binary options brokers:
• Choose a controlled broker: A regulated broker is the one which has obtained a license and is governed by the concerned regulatory authority. Picking a regulated binary options broker will benefit you in many ways such as, payment protection in case of the broker's insolvency, proper usage of funds and authenticity of the contracts.
• Access: There are some brokers who prohibit US investors from trading in binary option contracts. If you should be a US investor, you would want to check this first before proceeding to evaluate the broker on other parameters.
• Track Record: Pick a broker with a minumum of one year of reputable dealings. Avoid deciding on new brokers. The more experienced the broker, the higher will be its credibility as it has had the oppertunity to survive in this industry.
• Reputation: Before selecting any broker, ensure that you check the user reviews/ complaints which will give a fair idea of the trustworthiness of the broker. Find the broker who has good reviews and fewer complaints.
• User Interface: Since your entire transactions will be online, become familiar with the interface of the broker's website. User friendly and navigate interface will simplify things and assist you to take investment decisions easily.
• Number of Options: You can find a number of option variants including 60 seconds options by which the option expires after very one minute or One Touch binary option in that you simply need certainly to predict whether the asset price will at least one time cross a pre-determined price during the life span of the option. Brokers supplying a higher number of option variants are beneficial as it opens up more earning opportunities.
• High Payouts: Higher payout means lower commission to the brokers and obviously higher share of profits to you. Most brokers generally offer 80-85% payout in case the option is'in the amount of money '. Some brokers offer 10-15% payout even when the option is out from the money. Choose brokers with favorable payouts.
• Banking options: Since derivative contracts are about'timing'it is essential that the broker offers you fast and a range of deposit and withdrawal options.
• Customer Service: Fast and prompt customer support is just a big advantage for a newcomer trader. Test the broker's customer care with certain pre-account opening queries. Also, a demonstration account made available from a broker reflects its emphasis on superior customer experience.
• Terms and Conditions: More frequently than not, unfavorable terms such as higher withdrawal limit are hidden in the fine print of the terms and conditions. Read them in more detail before commencing trading with the broker.
It's important that you spend time in choosing your broker. The above checklist will help you choose the best binary options brokers in the market currently.

One of the fastest expanding kinds of online supplies trading today is binary alternatives.

How to really, truly calculate expected move?

Hi everybody. Hopefully this post doesn't sound too rant-y but I'm pretty frustrated by the amount of info out there that I'm not able to pick up on. There just seems to be a million ways to do calculated expected move. Here's what I've gathered so far.
There seems to be two general methods:
First Method: IV-Based
where P = price, IV = annualized implied volatility, DTE = days to expiration [0]
This means that there is a 68% probability that the stock in question will be between -1 and +1 sigma at the date of expiration, a 95% probability between -2 and +2, and a 99% probability between -3 and +3.
Sometimes 250-252 is used instead of 365, which seems to be the case when DTE refers to market days until expiration. Is that correct?
There are a number of ways to calculate IV. I would appreciate it if somebody could elaborate on which might be best and the differences between them:
  1. ThinkOrSwim uses the Bjerksund-Stensland Model [1] - I assume this is the "annualized" implied volatility aforementioned, because it is an IV value assigned to the stock as a whole ... what does that mean? I thought IV values were only calculated for a specific option contract??
    1. As an aside, ToS in particular confuses me because none of the IVs seem to correlate - Exhibit A
  2. I thought I might look into how VIX was priced off of SPY [2], as an analog, and use it as a basis for finding IV for any other stock as a whole. I don't know where they got their formula from
  3. Backsolve for IV using Black-Scholes [3]. This would only gives one value for IV, which I think only applies to that specific option contract and not to the stock as a whole??
  4. Some websites say to use the IV given that is closest to the desired time period [4] - of course I have no idea how the IV is calculated in the first place (Bjerksund-Stensland again? Black-Scholes?) What's the difference between using the IV of a weekly or a yearly option?
  5. Brenner and Subrahmanyam [5] - understood that this seems to be just an approximation. Should I be looking at formulas from 1988, however?
A very big question of mine is why there is an implied volatility for the stock as a whole and an implied volatility for every other options contract. I can kind of understand it both ways - why should a later-expiry contract have the same IV as an earlier-expiry contract? On the other hand, why should they be different? Why isn't there just one IV for the stock as a whole?

Second Method: Straddle-Based
My understanding is that this is more used for binary events like earnings, but in general I've found two methods:
I have no idea where [5] comes from and I can sort of understand 6 but not really.

In the end, I'm just trying to be as accurate as possible. Is there a best, preferred method to calculating the expected move of a stock in a given timeframe? Is there a best, preferred method to calculating IV (I'm inclined to go with ToS's model simply because they're large and trusted). Is there some Python library out there that already does this? For a retail trader like me, does it even matter??
Any help is appreciated. Thanks!

Weekly Dev Update 20/01/2020

Hey Y’all,
This week consisted of significant progress towards the Session release.
Loki Core
Lokinet
If you’re on our Discord you can catch Jeff, the lead developer of LLARP, live streaming as he codes at https://www.twitch.tv/uguu25519. He typically streams on Tuesday mornings, 9am - 12pm Eastern (US) time.
What went on last week with Lokinet:
This was an intense week for the Lokinet team; we identified some significant problems with the network resulting from the number of routers that came online on mainnet with the Nimble Nerthus hardfork. We initially pushed out a 0.6.3 release to try to address them, but that failed to work for separate reasons — this update ended up filling router queues with lokinet router lookups, causing even more messages to be dropped. So we went back to the drawing board and thought of several changes for a 0.6.4 release that we hope will improve network performance. We also developed a plan to address some more fundamental issues on the full-size network. This plan will be introduced in a 0.7 release, as it requires more drastic changes.
PR Activity:
----------------------------
Loki Messenger
Internal testing has now begun for the Session application, and we will be merging a number of new features into the Session rebrand codebase over the coming weeks, including private group chats, proxy requests and Sealed Sender functionality.
Loki Messenger iOS
Loki Messenger Android
Loki Messenger Desktop
Loki Wallets
New releases were published for all wallets which allow syncing past the hardfork and allow the user to send Blink transactions.

Cromton Tech Recovery Company

Out of the hundreds of binary options brokers in the world, there is only a handful that we currently recommend. These recommendations are based on my experience with the websites, the companies that operate them, and the features and quality each broker offers. Trust is always the number one essential criterion .
Those hundreds of brokers that do not make our recommended list have a variety of problems. Some of them simply do not offer enough in terms of features, while others are incompetently operated. Many however are actually flat-out untrustworthy. They are run by malicious individuals out to rob you. They are scammers, plain and simple. There are a lot of ways that binary options brokers scam customers.
Sell you useless systems and alert services. This is not really a scam you take action on if the systems were provided as a “free” benefit at a certain account tier, and it is questionable whether you could ever report them for it even if you did purchase them. Why? Because in the small print they invariably mention that the system does not guarantee results.
Manipulate expiry times and prices. This is one of the most common binary options scams and Forex scams. You are in a certain trade, and it is set to expire in a few minutes. At the time that the trade is meant to expire, you are in the money. But then for some unimaginable reason, the clock keeps running. A few seconds later, it stops, but the trade is a loser. The broker will claim it is a site error and point toward terms and conditions stating they are not responsible, but it is almost certainly malicious.
Refuse to pay out your money. This is another very common scam. You try to get your money out of your account and get a huge runaround. Either you find yourself wading through excessively complicated terms which are impossible to meet, you keep having to send in paperwork even though you already submitted everything, or the broker just ignores your withdrawal request and possibly disappears after absconding with your money.
What do you do if you think your binary options broker is scamming you?
Well, first off, you have to make sure they are scamming you. It is always a good idea to try to resolve the issue before you assume your broker is maliciously operating. If you cannot get the problem solved, though, you will have to take action against the company.
You can take the case further to a recovery company for them to assist you in recovering your funds from the fraudulent broker and the best company to achieve that for you is Cromton tech.
Cromtontech.org is a recovery company that assist victims of scams and bogus investment platforms to recover their private key and funds back in no time.

Managing High Availability in PostgreSQL – Part III: Patroni

In our previous blog posts, we discussed the capabilities and functioning of PostgreSQL Automatic Failover (PAF) by Cluster Labs and Replication Manager (repmgr) by 2ndQuadrant. In the final post of this series, we will review the last solution, Patroni by Zalando, and compare all three at the end so you can determine which high availability framework is best for your PostgreSQL hosting deployment.

Patroni for PostgreSQL

Patroni originated as a fork of Governor, a project from Compose. It is an open-source tool suite, written in Python, for managing high availability of PostgreSQL clusters. Instead of building its own consistency protocol, Patroni smartly leverages the consistency model provided by a Distributed Configuration Store (DCS). It also supports other DCS solutions like Zookeeper, etcd, Consul and Kubernetes.
Patroni ensures the end-to-end setup of PostgreSQL HA clusters, including streaming replication. It supports various ways for creating a standby node, and works like a template that can be customized to your needs.
This feature-rich tool exposes its functionality via REST APIs and also via a command line utility called patronictl. It supports integration with HAProxy by using its health check APIs to handle load balancing.
Patroni also supports event notification with the help of callbacks, which are scripts triggered by certain actions. It enables users to perform any maintenance actions by providing pause/resume functionality. The Watchdog support feature makes the framework even more robust.

How it Works

Initially, PostgreSQL and Patroni binaries needs to be installed. Once this is done, you will also need to setup a HA DCS configuration. All the necessary configurations to bootstrap the cluster needs to be specified in the yaml configuration file and Patroni will use this file for initialization. On the first node, Patroni initializes the database, obtains the leader lock from DCS, and ensures the node is being run as the master.
The next step is adding standby nodes, for which Patroni provides multiple options. By default, Patroni uses pg_basebackup to create the standby node, and also supports custom methods like WAL-E, pgBackRest, Barman and others for the standby node creation. Patroni makes it very simple to add a standby node, and handles all the bootstrapping tasks and setting up of your streaming replication.
Once your cluster setup is complete, Patroni will actively monitor the cluster and ensure it’s in a healthy state. The master node renews the leader lock every ttl second(s) (default: 30 seconds). When the master node fails to renew the leader lock, Patroni triggers an election, and the node which will obtain the leader lock will be elected as the new master.

How Does it Handle the Split Brain Scenario?

In a distributed system, consensus plays an important role in determining consistency, and Patroni uses DCS to attain consensus. Only the node that holds the leader lock can be the master and the leader lock is obtained via DCS. If the master node doesn’t hold the leader lock, then it will be demoted immediately by Patroni to run as a standby. This way, at any point in time, there can only be one master running in the system.

Are There Any Setup Requirements?

Patroni Pros

Patroni Cons

High Availability Test Scenarios

We conducted a few tests on PostgreSQL HA management using Patroni. All of these tests were performed while the application was running and inserting data to the PostgreSQL database. The application was written using PostgreSQL Java JDBC Driver leveraging the connection failover capability.

Standby Server Tests

Test Scenario Observation
Kill the PostgreSQL process Patroni brought the PostgreSQL process back to running state. There was no disruption of the writer application.
Stop the PostgreSQL process Patroni brought the PostgreSQL process back to running state. There was no disruption of the writer application.
Reboot the server Patroni needs to be started after reboot, unless configured to not start on reboot. Once Patroni was started, it started the PostgreSQL process and setup the standby configuration. There was no disruption of the writer application.
Stop the Patroni process It did not stop the PostgreSQL process. patronictl list did not display this server. There was no disruption of the writer application. So, essentially, you need to monitor the health of the Patroni process – otherwise it will lead to issues down the line.

MastePrimary Server Tests

Test Scenario Observation
Kill the PostgreSQL process Patroni brought the PostgreSQL process back to running state. Patroni running on that node had primary lock and so the election was not triggered. There was downtime in the writer application.
Stop the PostgreSQL process and bring it back immediately after health check expiry Patroni brought the PostgreSQL process back to running state. Patroni running on that node had primary lock and so the election was not triggered. There was downtime in the writer application.
Reboot the server Failover happened and one of the standby servers was elected as the new master after obtaining the lock. When Patroni was started on the old master, it brought back the old master up and performed pg_rewind and started following the new master.T There was downtime in the writer application.
Stop/Kill the Patroni process One of the standby servers acquired the DCS lock and became the master by promoting itself. The old master was still running and it led to multi-master scenario. The application was still writing to the old master. Once Patroni was started on the old master, it rewound the old master (use_pg_rewind was set to true) to the new master timeline and lsn and started following the new master. As you can see above, it is very important to monitor the health of the Patroni process on the master. Failure to do so can lead to a multi-master scenario and potential data loss.

Network Isolation Tests

Test Scenario Observation
Network-isolate the master server from other servers DCS communication was blocked for master node. PostgreSQL was demoted on the master server. A new master was elected in the majority partition. There was a downtime in the writer application.
Network-isolate the standby server from other servers DCS communication was blocked for the standby node. The PostgreSQL service was running, however, the node was not considered for elections. There was no disruption in the writer application.

What’s the Best PostgreSQL HA Framework?

Patroni is a valuable tool for PostgreSQL database administrators (DBAs), as it performs end-to-end setup and monitoring of a PostgreSQL cluster. The flexibility of choosing DCS and standby creation is an advantage to the end user, as they can choose the method they are comfortable with.
REST APIs, HaProxy integration, Watchdog support, callbacks and its feature-rich management makes Patroni the best solution for PostgreSQL HA management.

PostgreSQL HA Framework Testing: PAF vs. repmgr vs. Patroni

Included below is a comprehensive table detailing the results of all the tests we have performed on all three frameworks – PostgreSQL Automatic Failover (PAF), Replication Manager (repmgr) and Patroni.

Standby Server Tests

Test Scenario PostgreSQL Automatic Failover (PAF) Replication Manager (repmgr) Patroni
Kill the PostgreSQL process Pacemaker brought the PostgreSQL process back to running state. There was no disruption of the writer application. Standby server was marked as failed. Manual intervention was required to start the PostgreSQL process again. There was no disruption of the writer application. Patroni brought the PostgreSQL process back to running state. There was no disruption of the writer application.
Stop the PostgreSQL process Pacemaker brought the PostgreSQL process back to running state. There was no disruption of the writer application. Standby server was marked as failed. Manual intervention was required to start the PostgreSQL process again. There was no disruption of the writer application. Patroni brought the PostgreSQL process back to running state. There was no disruption of the writer application.
Reboot the server Standby server was marked offline initially. Once the server came up after reboot, PostgreSQL was started by Pacemaker and the server was marked as online. If fencing was enabled then node wouldn’t have been added automatically to cluster. There was no disruption of the writer application. Standby server was marked as failed. Once the server came up after reboot, PostgreSQL was started manually and server was marked as running. There was no disruption of the writer application. Patroni needs to be started after reboot, unless configured to not start on reboot. Once Patroni was started, it started the PostgreSQL process and setup the standby configuration. There was no disruption of the writer application.
Stop the framework agent process Agent: pacemaker. The PostgreSQL process was stopped and was marked offline. There was no disruption of the writer application. Agent: repmgrd. The standby server will not be part of automated failover situation. PostgreSQL service was found to be running. There was no disruption of the writer application. Agent: patroni. It did not stop the PostgreSQL process. patronictl list did not display this server. There was no disruption of the writer application.

MastePrimary Server Tests

Test Scenario PostgreSQL Automatic Failover (PAF) Replication Manager (repmgr) Patroni
Kill the PostgreSQL process Pacemaker brought the PostgreSQL process back to running state. Primary got recovered within the threshold time and hence election was not triggered. There was downtime in the writer application. repmgrd started health check for primary server connection on all standby servers for a fixed interval. When all retries failed, an election was triggered on all the standby servers. As a result of the election, the standby which had the latest received LSN got promoted. The standby servers which lost the election will wait for the notification from the new master node and will follow it once they receive the notification.Manual intervention was required to start the postgreSQL process again. There was downtime in the writer application. Patroni brought the PostgreSQL process back to running state. Patroni running on that node had primary lock and hence election was not triggered. There was downtime in the writer application.
Stop the PostgreSQL process and bring it back immediately after health check expiry Pacemaker brought the PostgreSQL process back to running state. Primary got recovered within the threshold time and hence election was not triggered. There was downtime in the writer application. repmgrd started health check for primary server connections on all standby servers for a fixed interval. When all the retries failed, an election was triggered on all the standby nodes. However, the newly elected master didn’t notify the existing standby servers since the old master was back. Cluster was left in an indeterminate state and manual intervention was required. There was downtime in the writer application. Patroni brought the PostgreSQL process back to running state. Patroni running on that node had primary lock and hence election was not triggered. There was downtime in the writer application.
Reboot the server Election was triggered by Pacemaker after the threshold time for which master was not available. The most eligible standby server was promoted as the new master. Once the old master came up after reboot, it was added back to the cluster as a standby. If fencing was enabled, then node wouldn’t have been added automatically to cluster. There was downtime in the writer application. repmgrd started election when master connection health check failed on all standby servers. The eligible standby was promoted. When this server came back, it didn’t join the cluster and was marked failed. repmgr node rejoin command was run to add the server back to the cluster. There was downtime in the writer application. Failover happened and one of the standby servers was elected as the new master after obtaining the lock. When Patroni was started on the old master, it brought back the old master up and performed pg_rewind and started following the new master. There was downtime in the writer application.
Stop the framework agent process Agent: pacemaker. The PostgreSQL process was stopped and it was marked offline. Election was triggered and new master was elected. There was downtime in writer application. Agent: repmgrd. The primary server will not be part of the automated failover situation. PostgreSQL service was found to be running. There was no disruption in writer application. Agent: patroni One of the standby servers acquired the DCS lock and became the master by promoting itself. The old master was still running and it led to multi-master scenario. The application was still writing to the old master. Once Patroni was started on the old master, it rewound the old master (use_pg_rewind was set to true) to the new master timeline and lsn and started following the new master.
Network Isolation Tests

Test Scenario PostgreSQL Automatic Failover (PAF) Replication Manager (repmgr) Patroni
Network isolate the master server from other servers (split brain scenario Corosync traffic was blocked on the master server. PostgreSQL service was turned off and master server was marked offline due to quorum policy. A new master was elected in the majority partition. There was a downtime in the writer application. All servers have the same value for location in repmgr configuration: repmgrd started election when master connection health check failed on all standby servers. The eligible standby was promoted, but the PostgreSQL process was still running on the old master node. There were two nodes running as master. Manual intervention was required after the network isolation was corrected. The standby servers have the same value for locationbut the primary had a different value for locationin repmgr configuration: repmgrd started election when master connection health check failed on all standby servers. But, there was no new master elected since the standby servers had location different from that of the primary. repmgrd went into degrade monitoring mode. PostgreSQL was running on all the nodes and there was only one master in the cluster. DCS communication was blocked for master node. PostgreSQL was demoted on the master server. A new master was elected in the majority partition. There was a downtime in the writer application.
Network-isolate the standby server from other servers Corosync traffic was blocked on the standby server. The server was marked offline and PostgreSQL service was turned off due to quorum policy. There was no disruption in the writer application. repmgrd went into degrade monitoring mode. The PostgreSQL process was still running on the standby node. Manual intervention was required after the network isolation was corrected. DCS communication was blocked for the standby node. The PostgreSQL service was running, however, the node was not considered for elections. There was no disruption in the writer application.
