The Cost of "Just One More"

Been trading long enough to know better, but last month reminded me sharply about the trap of overtrading. Had a decent week, two good setups on $EURUSD that worked out, then a smaller win on $XAUUSD. Everything was green, feeling confident, perhaps a bit too confident. Instead of stepping away, which is what my playbook explicitly states after three consecutive wins or a certain profit target, I started looking for more.

Found a messy looking setup on a low-cap crypto, something I usually avoid. Told myself it was small size, just for fun. It went south, fast. Then, instead of cutting it clean, I tried to average down. Another mistake. Before I knew it, a week's worth of solid gains had been significantly eroded by chasing an unnecessary trade, followed by the even more classic error of trying to fix a bad trade with another bad trade. The initial profit target exit strategy is there for a reason: to preserve capital and ego. Skipping it always costs. It's not about the individual loss, but the systematic breakdown of discipline. Lesson, again, learned.
