The main company is actually the latest main contract at present, so if you buy it, you actually buy the current main company. For example, it is now 2 109, the main pig, and your buyer even buys 2 109. If the main pig is replaced by another contract, he will buy a new main pig then.

First, the meaning of futures continuity
Futures continuous contracts represent futures contracts in the current delivery month (or the latest delivery month). With the continuous delivery and update of the month, the continuous contract will also be updated. For example, after the rebar contract was delivered in April, the continuous contract became the data in May.
Take the rebar futures contract as an example to explain in detail:
The picture shows the rebar contract list of Bo Yi Yun Shanghai Futures Exchange.
The delivery month of rebar is1-65438+February, and the delivery contract in May is normally rebar 1905 contract, so we can see that the continuous data of rebar is consistent with rebar 1905 contract.
Then, suppose we set the time to June 1 2065438, and when the Shanghai copper 1905 contract is delivered, the rebar continuously shows the market fluctuation of the Shanghai copper 19 10 contract.
Second, the meaning of futures company 34.
Futures Company III: The contract of the third delivery month after the current delivery month (or the latest delivery month).
Futures Company IV: Company III refers to the fourth delivery month contract after the current delivery month (or the latest delivery month) contract.
Third, why should there be continuous futures, continuous futures and continuous futures?
Because according to the law of market changes for a long time, traders find that the futures contracts one month and three or four months later closest to the current delivery month are the closest (most representative) to the spot expected price and the most active. Therefore, this contract price is constantly studied (throughout the year), so market data such as "XX continuous", "XX continuous three, even four" are set.
