As u said, someone buys at reversals and breakouts. But who buys or sells in the middle of support and resistance (I mean between reversals). Still there is order flow where there is no proper support and resistance , breakouts and breakdowns and chart patterns
True, I've also been puzzled by the order flow, especially when a market such as Crude has been hurtling down for weeks, still there are people who buy. At each price point a set of people think it is a low (and is going to rise), and another set thinks its a high (and is going to fall).
Besides the wide variety of trading systems that give rise to such decisions, other reasons may be ignorance, emotions, market makers, and who knows what other secrets are there? Or is it the planets who influence people to behave in different ways?
As for myself, at the beginning of my trading career, the trades I made then look downright senseless to me now. So greed, inexperience, stupidity, arrogance, all come into play...
