Found the TransActAT platform to be the cleanest, fastest and most stable in all my years of trading- and its free. all u guyys pay your $750 for TT- TransAct as good if not better
I use InfinityAT, which is essentially the same as TransactAT. The DOM interface is as simple as it can be, and the executions are incredible, and very fast.
The commissions are based on amount of volume you will be generating. But even a piker like me with less than 10 round trips per day could get the rates equivalent to IB's
