Hello, I am looking for a retail brokerage to trade cheap stocks. Because the trade size is usually pretty big the commission schedule should be per trade only and not per share like IB or Tradestation. I already have experience with Speed Trader and Fidelity. Speed Traderâs problem is the Penson which updates Buying Power only once a day before market opens. Thus, if you keep a position of a cheap unmarginable stock overnight, after closing the position you can not use those funds to trade the same day. Fidelity has really bad executions on Stop orders. Their Limit orders executions are ok. In term of Cheap Stocks execution which broker would you recommend Etrade, TDAmeritrade, CharelsShwab, or may be any other broker who has per trade commissions. Thank you
