1. Observe the change of volume: when the volume rises with the price, it is a buy signal. When the volume increases and the price falls, it is a signal to sell, but when the volume decreases, it is a signal to wait and see or expect a reversal, regardless of the price.

2. The amount of open contracts can also provide information: if the open contracts increase when the price rises, it is a buying signal, especially if the trading volume increases at the same time. On the other hand, if the open contract increases when the price falls and the transaction volume is large, the selling information is provided.

3. Pay attention to "extremes meet, people make mistakes": In the futures investment market, many investors are constantly enriching themselves. They may improve their philosophical knowledge, or their basic knowledge of finance, or their practical experience.
