2. However, in futures, the trading volume is not always much larger than the position, and the situation is different for different varieties and different maturities. Futures are different from stocks. Although the variety is single, they are all contracts that are uniformly formulated and stipulated to be delivered at a low point at a certain time in the future. The transactions of such contracts are all presented in daily transactions.

3. For example, when a futures contract is agreed to be traded after three months, when it is used as the main contract, the intraday trading volume tends to rise sharply, but the position has not changed much, and it often appears that the trading volume increases or even exceeds the position. But the later? The closer a futures contract comes to an end, it will no longer be the main contract, or a more forward futures contract. Because the number of transactions in the day is low, but the position exists, indicating that the volume of transactions in the day is less than the position.
