I believe their data is exactly what they claim it to be, OK for some methods/styles of trading unusable for others.
OKaaaaay ........ Maybe this is one of those methods/styles.
Trying to read a DOM or T&S tape and attempting to trade that data with IB's (or anyone's) aggregated data is IMO, similar to trying to catch a fart with a butterfly net. If your interest lies in trades/data made at this granular level of price, volume and time ,,,, I suggest you get the proper tools you need.
This is from the T&S Data posted on the CME Group website, (the one that counts)!
