I want to switch from IB to any firm who offers reliable platform with good pricing for emini sp,nq, ym, zb, and zn. I have looked at strategy runner ( manual order entry only) and j trader demos with few futures firms but did'nt like em. I am wondering about ffasttrade. Commision wise they are cheaper than IB and several other firms, but I have not seen their platform (pro version) and I don't have any idea about reliability (specially at the time of news and announcements). I would appreciate comments of any user of this platform. What is their margin requirements.
