Trading skills are important, but they are not as crucial as many believe. After establishing a system, there are many who cannot execute it. Therefore, fixed varieties, fixed cycles, and fixed methods, along with continuous and uninterrupted trading, are key! Trading is a game of 'seeking victory in defeat', where a few small failures can lead to a big victory. This model cannot be eliminated. Models of only winning or only losing do not exist. By deeply understanding seeking victory in defeat, one's mindset becomes calm; when to enter, one enters, and when to exit, one exits, without fear or hesitation. Both profits and losses must be reasonable; losses must be worth it to achieve reasonable victories. Stop-loss is a strategic loss, a cost incurred to potentially encounter a wave of significant market movements, and it is unavoidable. For many, stop-loss is a consumptive loss, where stopping ten times only leads to one or two significant market movements, and it is not guaranteed that they can hold on to it.
