I have started watching time and sales in an effort to improve my entries but kept seeing things that did not make sense. Orders larger than the cumulative level not moving price at all. Finally someone told me today that IB aggragrates trades. If this is the case why even bother with time and sales? I have been with IB for over a year and this is the first I have heard of this so thought I would bring it up for other IB users who are trying to watch time and sales. If this has been brought up before please link me to the thread as I could not find it on search. I am pretty happy with IB but this seems like something that should be fixed.
