yes, there are missin' prints but only for what concerns bid/ask not last sale...overall ib t&s is pretty much reliable. false spikes are on charts not on the tape, and size is not lumped together; even if more than 1 trade goes trough at the same time [second], every transaction is printed seperately.
Could someone advice the software with easy to use API or embedded programming language ? something like tradestation? (for eqity scalping needs, so it should be fast platform) thanx Alex
