um, maybe you missing the point? the point is the basis for it is probabilities. without that you would have no edge, just guess work. you may not be applying any maths or stats to it, but that is simply because someone else already has. for simple illustration, what is a moving average? it is a mathematical calculation! so to say no mathematics involved is misleading. but this a bit about semantics i admit, still it is counter productive to deny the existence of mathematics in it. more important is to acknowledge that success lies not in understanding the mathematics but in managing your money, risk, and so on. unless i am missing your point?
