I found quote from IB this morning is funny. It obviously lag behind scottrade's and very jumpy. And, the volume is ridiculous, too. Anybody has the same problem?
IB booktrader has had that problem for many months , probably always had it. As soon as the market is busy, the bid and ask become reversed and most entered trades aren't taken.
My update on IB data problem. later I tried tws 883 on my another computer. the quote was fine. Then I upgraded the version (884) with the problem to 885. The problem was gone. Just in time to catch RIMM's second leg down around noon. So guys who had the same problem can check the version you are using. If it is 884, you may consider upgrading to 885
