You can't use IB for T & S, to my knowledge, they don't show all ticks, the provide snapshot data so if you want to see T &S make sure your data provider provides accurate tick data and time stamps to the exchange.
I use IB for trading and TS for the charts and RADAR. the IB Time and sales gives you an idea from what I have seen but not all trades. If you look at the time and sales of say TS or eSignal you see them. Also, RJO is IB (you may be getting emails from RJO for your IB trading) Best of trading to you
Snapshot-based market data feed will drop quotes and aggregate trade prints. So if someone traded say 9 contracts 50ms before you did, IB would print 20 in T&S.
