I like QQQ and OEX where liquidity is good. I also like some of the larger more liquid stock options, but I always use best execution. My executions are usually instant (i.e just as fast as a stock trade), and where the option is quoted on all 4 exchanges I often find that there is no spread. True, when there is no spread the exchanges screw with their systems (and me) but thats why I stick more with the indices where I like to scalp in and out.
As for the stocks, if I buy 100 Yahoo then $1 commission is all that comes off my balance, (no ecn fees). I can choose to send my order to Archipelago, Island, Inca, Selectnet, Brass or Redi.
so don't think that they are selling the order flow.
