I'm assuming you made this post to differentiate from System and Method...and I agree 100%. The odds of getting a mechanical system that actually works is very low. But, I believe the traditional methods can make money, in the hands of a skilled trader. Sorry, if I didn't make that distinction clear. And if that's what mg_mg meant, that no "mechanical systems" work, then he's right, too. I'm sure that there may be a "System" out there that does make money, but the odds of you getting your hands on it and it being a system that suits your personality would probably be like winning the lottery...fat chance.
