Hi I primarily trade futures and right now my account is with TOS. TOS is good for option traders but mostly useless for futures traders. For example they do not offer a market depth feed and offer very few contracts to trade. I hear Mirus has low commission, good execution, good software, good feed, many exchanges to trade, $500 daytrading margins, and its free to request checks. Sounds pretty good I am thinking they should be my new broker unless someone here can convince me otherwise.
