I use Etrade, and you need to trade so many times a quarter to qualify for their 360 platform, that is where I get the level 2.
I wish I would have traded on the Think or Swim platform for my first couple of years with that paper money before I jumped into the game. LOL
If you want to chat or ask questions, The Trader's Perspective site is a good place, it is new and only a few posters, but good people trying to help one another. IMHO
