☝️In the top area, if the trading volume increases, it is not advisable to rush to sell, as this indicates that there may still be upward potential for the price; conversely, if the trading volume decreases at the top, this may indicate a weakening of upward momentum, and one should quickly exit at this time.

✌️In the bottom area, if the trading volume suddenly increases, it is not recommended to buy immediately, as this may be a temporary pause in the downward process that requires further observation; if the trading volume continues to increase, it indicates that funds are continuously flowing in, and at this time, one can consider entering to buy.
