I checked different broker price comparison at www.daytradingstocks.com
I am now convinced that IB commission is friendly. Rate it A+++
If one trades cheaper stocks in larger volume, like WCOM or LU or NT, may be other discount broker like scottrade has better comparative advantage. But if one trade blue chips like MSFT or IBM in a lot of 1500 shares or less , Interactive broker is a better choice.
Still it would be better for customers if IB sets upper limit on commission charge.
