Before the expiration of physical delivery or cash delivery, investors can voluntarily decide to buy and sell futures contracts according to market conditions and personal wishes. However, investors (bulls or bears) hold futures contracts without performing reverse operations (selling or buying) in the same delivery month and quantity, which is called "holding positions". In the futures operation of gold and other commodities, whether buying or selling, all new positions are called opening positions. After the operator opens a position, he holds a position in his hand, which is called a position.
For the algorithm of opening positions, it is calculated in China. The increase in positions represents the inflow of funds into the futures market, and vice versa. The impact on the price should be analyzed together with the volume.
