So NinjaTrader has taken over Mirus Futures.... I personally have never used Mirus, but from what I hear they seem to have a very good reputation.

Brokerage fees don't look to bad either

For people with a lifetime licence for NinjaTrader, roundturn rate for the following: 6A-$4.30, M6A(micro AUD)-$1.44, CL-$4.00, ES-$3.38, GC-$4.00, FDAX-$3.03
