There are many forex tips on the net, but the best, most succint gems of distilled forex trading wisdom are here.
Tip #14 Beware of the forex broker
The forex market is littered with what remains of day traders and genius 'systems,' and to survive in the long-run, forex traders have to realize that they are playing a game where the cards are clearly stacked against them. Slow order filling, stop hunting, slippage, trading against clients (i.e. not offsetting your trades), weird spikes that don’t show on other platforms, and a few more are all in the bag of dirty tricks of the unscrupulous forex broker. Don’t get us wrong – you can make money trading forex, but you must be aware of the practices of your best forex broker.
