Remember the ancient rule of the market: the losing position should be terminated as soon as possible, and the profitable position should be held for as long as possible. Another important rule is not to let losses occur in positions that have already been profitable. In the face of sudden market reversals, it is better not to close positions that have not been profitable, nor to let positions that have already been profitable turn into losses.
--切勿有急于翻身的交易心态--
In the face of losses, it is important not to rush to open new positions in the opposite direction in order to turn around, as this often only worsens the situation. Only in situations where you believe the original predictions and decisions are completely wrong can you quickly close the losing position and open a new reverse position. Don't play guessing games with market changes. It's better to miss trading opportunities than to incur losses.
