A lot of the favored brokers here use No-Dealing-Desk technology. No person is making individual decisions on your trades, they are all sifted/sorted/matched by computer...usually in under a second.

There's a cadre of voices on this forum which say that people who complain about their broker stabbing them in the back are really just looking for someone to blame. I tend to agree with them. I always get the impression that most of these people have bank rolls that are rather small and thus their respective position sizes are also small and thus there's really no reason for a broker to try and skim a bit more from these small positions by manipulating things. It would be better business (and less stressful) to just let people do what they want and collect the spread.

So look for reputable brokers, and you should be find. Names like Pepperstone, FinFX, Alpari, Oanda, MB, Dukascopy, MIG Bank, FXDD, AAAFX, and IBFX all seem to fall into this category. I'd start by researching those brokers. Unless you're in the US and want higher leverage and no FIFO or hedging restrictions...then FinFX is the only game in town.
