Futures position difference is the abbreviation of position difference, which refers to the difference between the position of the current day and the closing price of the previous day. If the futures position difference is positive, it means that the position has increased on that day, and if it is negative, it means that the position has decreased. Position difference is the change of position.

In futures trading, whether buying or selling, all new positions are called opening positions. A trader holds a position in his hand after opening a position, which is called a position. The increase in positions represents the inflow of funds into the futures market, and vice versa. The open interest contract of futures refers to the total open interest contract of a contract held by investors, which is the amount of a commodity futures contract that has not been hedged and delivered in kind after buying or selling.
