There is no total crude oil position in a single contract. Crude oil futures contracts are time-limited. Before the expiration of the contract, the warehouse receipt held by the dealer should be closed as required, otherwise it will easily lead to forced liquidation. The time limit for traders to hold fixed contracts is not long, especially when there are many main contracts for traders to trade. The total position of all contracts of a futures product can be seen on the game master trading software, and it is a contract. For example, the main contract position today is 654.38+ 10,000 lots, which is 654.38+ 10,000 lots. Then add other non-main contract positions, which is123,000 lots, so this operation is reflected in the game owner.
