Folks,

It's been some 10 years since JBookTrader public development was suspended because it was licensed commercially. Many of you have probably lost interest or even forgot what JBookTrader was. However, for those of you who still remember it, I am happy to announce that JBookTrader is now back.

Over these last 10 years, development of JBookTrader was still going on in the private mode, with many improvements and fixes. 

Now, I am releasing JBookTrader back into public domain:
https://github.com/nonlinear5/JBookTrader

I am planning to run this very version of JBookTrader live, for my own live IB account. So, effectively, I am sharing my trading system with you. However, I am holding back my privately-developed strategies and market data. I am giving you the platform, and it's up to you to develop your own strategies on that platform.

Thanks, and I look forward to your contributions to this project.

Eugene Kononov,
JBookTrader founder.

Hi Eugene!

Nice hearing again from you.  I didn't forget and I'm still developing trading bots.  I didn't know you had it licensed.  Any more details you can share?  Is it still commercialized?  What significant changes were made?

The world has changed a lot since then and unfortunately there is a risk that your account got compromised and the whole come back thing isn't made by you but by an attacker who sneaked a backdoor in the code.  Gonna need more inspection and security reviews compiling and running JBT again.

Hi Florent, good to hear from you. No, my account has not been compromised, and it's really me, Eugene Kononov. Regarding the commercial license, it's expired now, so that's why JBookTrader is back into the public domain.

Good to hear from you, Eugene. Been thinking to put some things in the public space myself as well. And fun to see the responses here. If I didn't know better I'd suggest a meetup at some point...

A few questions, with a theme perhaps:
1. Does the commercial license expiring mean we get the benefit of the development you (or others) did on jbt while it was under license? Or are we starting at "last known good"?
2. I spent years (decades?) in java, but now I never use it nor really know anyone who does. Is Java still your choice for the platform?
3. JBT was very cool at the time, but is quite old now. Are you thinking to completely overhaul the architecture?
4. Several more "obvious" questions but maybe just: are you planning to integrate AI or ML techniques into the platform?

All in all, I will very likely contribute whichever way you go. But want to understand the new/current vision.

This is a notable day then.  Great news. My JBT story.    Tinkered with JBT and adapted it to trade record data for  option strategies ( spreads ) thinking maybe there was a 0DTE angle to exploit.  Also I refactored it to a multi service/multi project  architecture having a desktop client for backtesting and generating data.  web front end for reports, and trading microservice for execution.  tested it and performed a few trades but then kind of stopped working on it.
