Quote from Thunderdog:
Not necessarily. People cannot really test TA per se because TA is not a trading method. They can only test methods incorporating elements of TA. I think that the problem is two-fold. First, most, but not all, of TA is BS. Second, the stuff that gets tested is the lame generic crap that no one in their right mind would trade anyway. And guess what? If the testers came across a method that actually performed well, do you really believe that they would publish both the method and its results?
