Extended data:
A futures contract is an agreement in which the buyer agrees to receive assets at a specific price after a specified time, and the seller agrees to deliver assets at a specific price after a specified time. The price that both parties agree to use in future transactions is called futures price. The designated R period in which both parties must conduct transactions in the future is called the settlement date or delivery date. The assets that both parties agree to exchange are called "targets". If an investor obtains a position in the market by buying a futures contract (that is, agreeing to buy it at a future date), it is called a long position or a futures long position. On the contrary, if the position obtained by investors is to sell futures contracts (that is, to assume the contractual responsibility for future sales), it is called short positions or short futures.
The difference between futures and stocks is that the life cycle of futures contracts is limited and will not be delivered until after the last trading day of the contracts. The so-called main contract refers to the contract with the largest position. Under normal circumstances, the contract with the largest position has the largest turnover. Because it is the most active contract in the market and the easiest contract to clinch, speculators are basically participating in this contract.
The main contract of commodity futures is only produced in three contracts: 65438+ 10/May/September. For example, 140 1, 1405, 1409 will be used as the main contract in turn over time. Stock index futures is the main contract of the month.
How to judge which is the main futures contract?
Look at the delivery time.
Contracts that have been listed for more than 1 month and are more than one month away from the contract delivery time can be operated. In other words, don't operate the new contract, and don't operate the contract close to delivery. Even if it involves, it is best to clear the warehouse before clearing it.

Every contract will have a relatively constant position when it runs to the mature stage. Compared with the turnover of all futures contracts of a certain variety, the largest is the main contract.
