Scenario 2: If the purchased price is in the middle range, you can temporarily wait and see based on the situation at that time, in order to unwind and leave the market or reduce losses when the position is high.
Scenario 3: If the purchased price is at a low level, there is no need to rush to stop the loss. After the purchased price stabilizes, one should dare to cover the position at a low level in important support positions, dilute costs, and rescue the high locked position together in the subsequent rebound market.
