Anybody who has been around the forex market for over a couple of minutes knows that you always need to test forex systems before you go live with them. Even if the system comes with guarantees, even if you got it from a top trader who makes millions with it, you have got to know that it will work for you. They imagine there is one perfect system out there that fits everyone and could make us all into millionaires if only we knew how it’s possible to get a hold of it. But that idea is a complete fantasy. It could involve some talent like interpreting a complicated mix of indicators that some people will handle with no trouble while others cannot get their heads around it no matter how hard they try. It could be to do with risk : the system could involve going to an amount of risk which would be way outside some peoples’s comfort sectors, leading them to either subvert the system or mess up due to the level of stress. So you should test and you can do this in more than one way. The best option is to perform at least two sorts of testing which you can do at the same time.
