I had a trial (with paper trading) with ToS a while ago, before the Schwab acquisition. I didn't find their platform particularly compelling, so I went back to using StreetSmartEdge by Schwab. Can you explain why you find ToS better?
I like StreetSmartEdge better but I would say ThinkOrSwim is much better on mobile especially for options. Real time quotes go a long way and the options are displayed in a condensed fashion.
