@gmst: Have you reached a conclusion: Is the data from IB wrong, or are you displaying it wrong? How are you displaying it?
I simply clicked on T&S window in IB and tried different options like displaying only trades or trades + bid ask size etc. I don't think selecting any of these different options can lead to re-ordering of trades that are printed in T&S.
So, I think my display is not wrong.
