The previous trade was like dancing on the edge of a knife. The close position line was stuck at just above 3097 points, and the market data peaked at 3099—just two points away from liquidation.

My heart almost stopped, but fortunately the price fell back. Seeing that my account had a floating profit of over a hundred dollars, I almost reflexively closed my position.

But after calming down, I began to ponder a question: why is it that when making a profit, I always think about taking the money and running, but when I incur a loss, I can endure it until the end of time? Does this operation logic of "taking small profits quickly and holding on to large losses" actually become the root cause of most people ultimately losing money?

Perhaps it's time to reevaluate your trading system - how should the standards for take profit and stop loss be set? It cannot be based solely on feelings and luck.
