1. If the price rises quickly but falls slowly, it means that the main funds are quietly accumulating chips and preparing for the next wave of pull-ups.

2. If the price falls quickly but rises slowly, it means that the main funds are gradually selling, and the market may enter a downward phase.

3. Don't rush to sell when the top volume increases, and run quickly when there is no volume at the top. If the top volume is large, it means that there may be room for further increases, but if the volume shrinks, it means that the momentum is insufficient and it is time to withdraw.

4. Don't rush to buy when the bottom volume increases, and consider it again when the volume continues to increase. The bottom volume is sometimes a signal of a downward relay, and you can't blindly enter the market, but if the volume continues to increase, it means that funds are entering the market, and you can consider layout.
