In a word, 'yes', you can live trade with TWS.
TWS/IB also provides a 'demo' account and you can sign up for a 'paper' account, both helpful in developing and testing a strategy.
I see the forums here are real dead like, dont see daily posts and discussion
I have installed and connected to TWS and charts pulled up, and created a new trading system and added indicator, and don't
know how to proceed next. read help file, and dont say about building trading system by drag and drop as I know nothing about programming
what forum category should I post this
