Quote from RedRat:
I like VelocityFutures via FIX protocol. Commissions are 3.75/round for e-mini futures. Compare that with Mirus around 4.50/round.
Are you getting data through FIX? Is there any performance concern?
My understanding is that FIX is a text/tag based protocol which I'm a little concerned would be somewhat inefficient for providing data.
If you use it for data, could you comment? Thanks!
At least for now
