Noticed that a couple of retail brokers that do 80bpm. As opposed to 80 bpd at higher levels like icap via primebrokers.
This indicates to me they (retail) could do more - lots of trades with low liquidity risks. Think they are via Integral or tradingtech maybe.
I wonder about citifx. They have a wholesale arm, but I wonder if their retail mt4 portal taps into that. I wonder who is doing the largest and using mt4 too. (fxcm excluded of course).
