Yeah, I ended up taking https://github.com/gofinance/ib and rewrote my own wrapper. This took a long time but has been stable since. I'm basically only doing buy lmt, sell lmt, cancel, and updates orders though. So, the logic is pretty simple. Catching all the return messages and structuring them correctly took tons of debugging, trail, and error. Basically, mapping the messages into the correct orders for state tracking.
