1. The life cycle of a futures contract is limited, and it will be delivered after the last trading day of the contract. 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.

2. Most futures contracts have a delivery period (some are indefinite, such as LME March copper, which will be explained later), and the longest contract period usually does not exceed one year. In order to facilitate research, many market quotation systems have set up "continuous contracts".

Such as Shanghai Copper Company Limited, Shanghai Copper Company Limited, Shanghai Copper Company Limited, Shanghai Copper Company Limited, etc. The continuous contract here does not refer to a specific contract, but a change. For example, XX Co., Ltd. is the contract of the current delivery month, XX Co., Ltd. is the first trading contract after the current delivery, XX Co., Ltd. is the third trading contract after the current delivery, and so on.
