im pretty happy with suretraders DAS trader pro.. im paying for a papertrade accout thru https://www.warriortrading.com/paper-trading-with-das-trader-and-warrior-trading/

I like equityfeed for charting and streaming news, but it can be pricy. I also use TD ameritrade's level II. read my blog for background info http://trading-elixir.tumblr.com hope this helps

try em all (free trials preferred, if any). You'll find the one you're comfortable with. I personally like ThinkorSwim from TD Ameritrade

you can open a TD Ameritrade account and not fund it and get Think or Swim for free.
