Quote from cstfx:
I think someone here posted a ping test and it was something like 15ms us server and 250 ms hk server. Granted, we are talking a fraction of a second, and for most people that's not an issue, but there are some arb'd traders that ned that time. i think you notice it more if you are trying to trade the L2 quotes and such. If adding liquidity, it SHOULDN"T be that bad.
Correct me if I'm wrong since I'm not an arbitrage trader. They shouldn't choose IB anyway because IB requires too much margin (even overnight margin for daytrading some liquid futures :eek: ). They should pick a firm which provide competitive margin for this kind of trading style.
