Quote from hedgeking:
if you take liquidity on nasdaq stocks all day long you'd have to be at .001 or less prop to beat ib's all in. if you trade goog or rimm and do all markets ib's losing money as the sec fee is about .005 per share alone. if you mostly do nyse ib's .005 rate is not good
Quote from qll:
sec fee is 0.005 per share?
i know discount brokers like scottrade or ameritrade, will only charge $10 or less. i know they may cheat on market or active orders, but if you provide liquidity by using passive limit orders, your orders will be shown to the level2 book pretty quickly, so there is nothing to lose from our end, then you mean ameritrade, IB, scott are all losing money to provide us a service?
