the Simplest Way to Test Your System

Any source of foreign exchange trading information will tell you that you will need to test a currency exchange system prior to going live but how precisely are you able to do that? The reality is that you should do it in more than one way. Historical charts are supplied free on many FOREX trading information websites. It is vital to apply the rules of your system in a practical way when back testing. So for instance, if you’re using an EMA crossover system, you could spot a crossover on a past chart that was followed by a 200 pip rise. Do you write down that you would have made 200 pips from that trade?
No, it is probably unrealistic. Most systems need you to do that. In that time the price might have modified.
Then you have to think about where your stop loss would’ve been and whether there were any fluctuations that would have caused your stop loss.
Ultimately, consider where you would have closed the trade. If your system aims for a hundred pips profit per trade, you would have closed at this point and missed out on the rest of the price movement.
