I have seen something that really scared me. I work with IB and for the migration I am working with two computers. One with NT7 and the other one with NT8 installed. Both use the same datafeed from two different account from IB. The data is supposed to be the same for both because both accounts have exactly the same subscription.
Even so, the loaded volume data is completely different.
I attach two screenshots for the data of SPY for you to compare. Why the volume data is different?
