Hey semp so I use IBKR pro and their TWS platform. It is pretty good, stable but the UI could be better. Pretty shit for options though apart from placing the trades and combos. There are plenty of vids and articles how to use it so check them out. I would advise to go paper trading option first so you can play around with it and get use to it. I see you use CQG so in regards to learning curve TWS would be easier than CQG to learn from scratch.
