This dataset collects pre-market information for futures products, covering major contracts, continuous contracts and other associated details. The open interest-based dominant contract is defined as the contract with the maximum average open interest over the prior three trading days, and it will not be subject to repeated changes within one month. Similarly, the trading volume-based dominant contract is the contract with the highest average trading volume over the previous three trading days, with no repeated adjustments within one month. The markers for dominant and continuous contracts are updated after the market closing on day T-1.
