I prefer the currencies futures as they have options to hedge my trades. Can always expect one tick plus spread in futures unless you use limits. I do have an accounts in forex for reports that will make currencies move, sometimes one or the other have slight hesitation right after report to get trade off, but the exotic spreads, pips just too wide for my style of trading, and slippage on stops I can only guess could be large at wrong times. If you looking for 100 pip or greater move, then 10 pip spread won't hurt too often. I do day trade some litely covered commodities and moves can be incredible like in Coffee, Cotton and OJ, but when you have to get out, there is a price to pay as volume dries up.
