What is the most painful thing in the trading process? It is the feeling of powerlessness when you feel you are right but still lose money, the self-blame of greed and fear that ruins profits, the regret of missing opportunities, and the self-doubt of continuous losses. You must first learn to "lose stably" before you can achieve "stable profits". When you are unwilling to stop loss, ask yourself, if the market does not turn around this time, how long can your account last? Do you have enough funds to hold on? Do you still have a chance to stay in this market after holding on to the end? Why does the trading system fail in your hands? Because the implicit conditions in the system are ignored, the human factors are magnified during the execution process, the position management is not matched, and there is survivor bias. "Enlightenment in trading" is a statement that deceives retail investors. The real enlightenment is a change in cognition, and the false enlightenment is a marketing of "creating gods". Traders must have the ability to explore the essence of things. The end of trading is "closing the account". If you can't establish a stable trading logic, leaving is the best choice for these traders. The end of trading is never determined by tools, but by the cognition of traders.
