Hi All- I've been day trading my accounts profitably for a few years using TD Ameritrade and Scottrade platforms. I'm tired of the crappy executions and high commissions, which I figure have probably cost me thousands over time. I have decided to move to a more professional platform, what would you recommend I use? I will most likely have a few hundred grand in cash, will trade only equities and ETF's, margin is not hugely important, I want to have good charting and execution. IB seems to get alot of mentions on here, is that a good place to start?
