What products are you intending to trade? I primarily trade ES emini's, have a ToS account and intend to move it. Recently demo's the BestDirect platform w/ PFGBest, it was the closest to live trading I've experienced. By that I mean one does not get an instant fill when a limit or stop price trades, but it simulates actual fills, unlike paper money w/ ToS, or other simulators I've used.
