Hello all! We are from a long-standing FX fund management background, dating back to 1998. We have found over the years that it most certainly matters where you trade to reduce slippage on large volumes. In this case the large tier-one banks are usually better. But here is my question. In the futures market, does it matter at all which broker you use? The difference with FX is that there is an actual formal exchange for the futures instruments. Does it matter if you go to either IB or NewEdge? Surely they (should) both fill your order at the same level / slippage / even in large volume? My focus here is specifically fills on large volumes, I am not interested in soft issues like client service, etc. Any advice will be greatly appreciated.
