Not paying attention to backside. Greed (could have exited at 12-12.5 but thought it was going to 15). No cutting losses. Got cocky. Had a very high win rate last couple days. Ignored multiple rules (be less aggressive on backside). I told myself I'd most likely sell in the 4s later today. I was right, it was weak and i ignored all my rules and patterns anyways. I cannot get cocky again. I was up over 10% today and was not happy with it.
