I use my phone in the day to trade. I use etrade to watch and otcbb to check L2 trades and then that free L2 for depth. Only the etrade is live. You can check past days trades on etrade pro under time and sales I believe, then key in the dates. I have been too busy at work lately to trade too often.
I notice the 14's have beefed up, we'll see, maybe that will be the battle ground rather than 12.
