The position of stock index futures generally refers to the contract held by traders after the day's trading. He may have bought the contract or sold it. In addition, during the trading period, traders open positions to buy or sell stock index futures contracts, which can also be called holding stock index futures positions during the period when they have not temporarily closed their positions.

As mentioned above, as long as traders open positions to buy or sell, they can be called positions. Selling and holding stock index futures contracts is only a case of holding positions.
