I have been trading online for many years and have used many brokers. I will tell you to stick with the bigger names. Don't use a small time broker. I made that mistake with Choicetrade. I never used Scott, but have used both Ameritrade and Etrade. I like them both. But Etrade all around, imo, is the best. They give you Etrade Pro for free if you are an active trader. Go here and take a look at Pro - click "take a tour": https://us.etrade.com/trade/etrade-pro
