If you're learning how to read market charts, learn the kind that most people use, like support and resistance. There's no need to adjust any special parameters for technical indicators; the default settings are fine.

Because, to put it bluntly, it's just a matter of public psychology. When most people think it's a good time to buy, the price will naturally go up.

But if you learn those flashy techniques, I admit that you might succeed a few times out of ten, but from the perspective of public psychology, only a small number of people will choose to buy there, which means you're effectively without support.
