No, I'm not staring at a duck, when I'm looking at a chart (on print, on screen, be it realtime or not), I'm always trying to see a pattern. Looking for anything that indicates price doesn't move random. Sometimes I see some things, other times I'm unable to explain why it swings up or down, gaps up, drops down, moves sideways, etc... But as you pointed out, it's not my task to explain all this I just need to find a way to profit out of it. So no, they don't seem ENTIRELY random, but they don't seem to behave in a way that can be predicted neither. Ok, you'll probably argue t's all about probabilities, but suppose I see a signal, backtest it and it turns out 7 out of 10 (or 70 out of 100 for that matter) actually move up further after that signal. That's no way of saying it will work again, next week, month or year things could be totally different.
