Hi there. Currently i'm looking to upgrade my trading environment. I'm with Ninjatrader now (platform and brokerage), but looking to switch back to TT again. When i last was using TT i was with AMP. But i wasn't very happy with the service. I'm increasing my trade amount substantially, so i'm looking for a trustworthy party. And commissions are also very important, since i'm a scalper. I always heard it was best to use a FCM, since IB's are just the middleman.
