I just spent half an hour reviewing a losing trade that I felt pretty frustrated about. Honestly, it’s not that I was wrong about the direction; I was just too impatient. At that time, I saw the fee rate reaching an extreme, and the group was arguing whether to reverse or continue squeezing the bubble. I got impulsive and chased in, only to find that the depth was as thin as paper. The market price hit and I was immediately caught with a high slippage "bagholder."

Looking back, there are three pitfalls: First, only watching the K-line without paying attention to the order book; when the order wall was pulled, I was still rushing in. Second, my order placement rhythm was chaotic; splitting into two or three smaller orders could have reduced my losses significantly. Third, I didn’t set a tight slippage limit, thinking "it shouldn’t be much different"... and that was the most deadly mistake. In future emotional turning points like this, I’d rather earn less and place limit orders to wait. If it doesn’t fill, so be it—life is more important than face.
