What does fooling have to do with anything? If a trade doesn't do what one expects it to do, why hang on? Hope?
You asked if he was a supply and demand trader. Aside from the question of whether or not he's a trader, why else would he make the investments he does?
I assume you meant why am I trying to convince everyone? And I'm not. I responded to Light's assertion that trading methods (or approaches or systems or whatever) don't last. You took it from there. We can drop this anytime, lols and all.
