A system won't work by itself...it needs a trader to take advantage of it when it's in the "best interest" of the trader to take the given profits.
Not all signals in any given system are created equal. Some are valid, some are fake...some are strong to get many pips, others will give some but may not reach the target before becoming a loss...how will you know the difference?
Just about any system will work, but if you work it like a robot, it won't do as well as if you work it with an edge/knowledge. You get that edge/knowledge by "doing all that work".
Just like driving...sure the car works but do you know how to drive? Did you learn to read the street signs, know what the instruments/switches on the dashboard mean/do...cause if you don't you'll surely get into an accident!
