The difference between futures and stocks is that the life cycle of futures contracts is limited and will not be delivered until after the last trading day of the contracts. 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.

For example, on August 28th, 2020, Apple Futures will include Apple 20 10, Apple 201,Apple 20 12, Apple 2 10 1, and Apple 20/kloc-. The first two digits of the futures contract name indicate the year, and the last two digits indicate the month. In addition, the main contract of a futures variety is not static and will change with the passage of time.
