There are lots of resources which can teach you how to trade on forex, however not all of them are really effective. Here you should pay attention to the reputation of the resource and understand whether its courses are deserved to be noticed by your or not. There are also lots of brokers who provide traders with access to educational courses. As a rule brokers are directed to the education, because it's a direct consequences of their further work. If they would treat traders bad, then they wouldn't receive money. So, I would advice you to pay attention to brokers' educational courses actually.
