Because the main contract is the most active contract in the market and the easiest contract to clinch, this contract is basically attended by speculators. Generally speaking, the contract with the largest position is also the contract with the largest turnover.

Master contract and non-master contract exist at the same time. As the expiration date approaches, the positions and turnover of a main contract will gradually decrease until the contract ends on the delivery date. At the same time, the trading volume and positions of forward contracts will increase with the passage of time and gradually become the main contracts.

Extended data

The K-line trend of the main contract is clear. Some friends who just operate the spot will do it as soon as they grab a contract. Sometimes, they will find that the K-line of some contracts is grotesque, jumping more than ten points a minute, and the pending orders will not be closed for a long time. These contracts are actually non-main contracts, which are generally close to delivery and have no operational value.

The main contract will change. When the current main contract is about to expire, move the funds to next month to understand the position of this month's contract and trade a new contract.
