How to test a Metatrader robot (Expert Advisor)
Once I either finish a robot, or buy a robot, I like to spend some time testing it in Metatrader against some historical data. Usually I will start out with about a 3 year period. If the robot passes that test, then I will try it out on short and longer time frames to see what happens.
The strategy tester in Metatrader 4 is actually pretty good and runs pretty fast after you download the data from the historical data section.
