Depends on what your trading style is and how much money you're talking about, but if you're asking then chances are that you don't need anything crazy. www.oanda.com I hear is pretty good. www.interactivebrokers.com is great if you just want one stop shopping with your other markets. You don't get it 24 hours though. (It's the one I use to hedge the currency exposure of my US stocks... I live in Canada) Good luck, DTK
