Okay, I am sure we all here have learmed about everything and anything regarding price action, head shoulder, 1-2-3, double shirt, flag, etc etc.. But I read a book that revealed a chart on coin toss and daily temp chart, it appears exactly like commodity charts, which looks like many comparable patterns. My qusetion is, I am sure temp isn't man-made, and it has been deemed that it is not predictable at all. what about commodities?
