This.  Robinhood is by far the best day trading platform.  Ive tried all of then in my endless cycle to get around my numerous pdt flags and i prefer robinhood vastly more.  I use td for the charts though.  Anything but td and rh arent worth the time.

TD has a decent mobile app interface? I'll have to look into that. I would love 3 and 5 minute candles, and MACD. I'm decent at eyeballing it, but it would still help.
