Noticed what seems like odd behavior in TWS time and sales windows: two windows for the same instrument show different information. The windows are for 1 minute and 5 minute charts for March YM. I'll try and attach a screen shot. The shot was taken right when I noticed the difference on Feb. 17. Apparently it's not uncommon--I just looked at T & S windows from Friday and found discrepancies in the first 2 time periods that I looked at, in trading acct. as well as sim. I messaged IB about this but haven't heard back. It's unsettling to see the different data, and it would be nice to know what's going on.
