It is not the main force to change the moon, but the delivery of the original contract. The new listing contract is connected with the K-line chart of the original contract.

Since newly listed contracts are usually delivered one year after the delivery (delisting) of the original contracts, when people think that futures prices will fall after one year, there will be a huge gap.

In fact, the original contract and the subsequent contract are two unrelated contracts.

The main changes in the month are gradual and have little impact on the price.
