I know a lot of traders who trade FX spot with spread ranging 3-5 pips. When I trade FX let's say EUR/USD -I use Eurofutures where spread is 1 pip. Futures following the spot tick by tick most of the time so basically they serve as the proxy for the spot or the other way around (less the time value spread) I really dont understand why people would trade the spot and give away 2-4 pips? Is that the leverage/margin reqs? May be liquidity but I have no problems flipping 8-10 contracts.
