It took some modification/debugging to make JBT work with the new version of TWS API, but now JBT looks good. I see some folks forked the repo, so update your forks.
To put JBT to the test, I ran it for a day with a paper account, and it flawlessly executed 4600+ trades. The corresponding testing strategies were designed just to generate a large volume of trades, and that's why you see a large net loss.
I am planning to go live, with real account, sometime this week. I'll be using the same exact code base as available in GitHub, but with custom-designed, hand-picked, historically tested strategies using S&P micro futures.
