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).
