MushinSeeker, I think it depends on a few things. The choice should be made on what your needs/wants in a broker are for your specific trading, IMO. If you want/need to start small in FX trading, Oanda has an advantage of allowing you to use any trade size you want, no minimum trade size. They don't charge commissions but it is in the spread, that is how I see it. IB's advantage has nothing to do with spread/comm to me. I don't think your end decision should really be made on who has the tightest spread/comm between your FX brokers, it seems like a big marketing ploy. If this is what your looking for, I can only assume you are attempting to scalp FX which I would say... go to the casino... more fun.
