Flipping through the trading records, I suddenly realize that my account curve is just like a life chart—full of ups and downs. The actions I thought were the smartest now seem to be the most outrageous decisions. Chasing highs and selling lows, frequently switching coins, ignoring risks... one mistake after another, stubbornly turning the K-line of my principal into a roller coaster. Sometimes I realize that the real trading mistake isn't in market prediction, but in what I was thinking at that moment. Every time I review those trading records, I can't help but want to criticize my past self.
