I noticed that when trades come in at high frequencies the sales are reversed. For example I would see 2,87,1,1,3 in TOS and IQ feed would show 3,1,1,87,2. This only happens when a lot of fills take place at one given moment. I am using Ninja Trader to connect to both the IB and IQ feeds and base-lining against TOS. How can I verify which is correct? I don't notice this in the IB feed either. I attached an example and I have version 4.7.2.0 dated in 2010. Edited by rcardare on Jun 8, 2011 at 10:11 PM

I don't believe this is a NT issue or an IQFeed issue.
I verified the ordering of the trades in that screenshot versus our internal storage (which rules out a NT problem) and also against another vendor (which gives evidence to this not being an IQFeed issue).
