Are executions on QQQ (AMEX) as fast as using a direct-access on Nasdaq Stocks like INTEL? I mean, when trading Nasdaq, a market order is executed IMMEDIATELY! (less than a second)! What about QQQ? How long it takes? What's different between NASDAQ and AMEX, in terms of trading? Since I have never traded QQQ before, I decided to ask you guys who have already traded QQQ. Thanx for your time. Good Luck trading!!! Raphael
