I posted in other forums, and found the right place here, finally. Thinking about upgrading to either one. Pro's and Con's ? Who's better for daytrading stocks and options. I usually close positions intraday and trade channeling stocks. Don't hold position long term. Have been using Fidelity's Active Trader Pro which does a fair job but not beyond. I used it because its free but maybe its time to upgrade. Please give me your opinion on these 2 platforms or suggest another trading platform. I am fairly capable as a rule's programmer so I think I can handle some of the intricate options of a trading system. Thank you in advance.
