That's not what clearing the list means. Due to risk considerations, institutions generally hold long and short orders at the same time, but the number is different. A bullish market is flat, a bearish market is flat, and vice versa. When calculating the customs clearance form, deduct the variance form. For example, if a main force holds 65,438+00,000 hands empty, and more than 8,000 hands empty, then it is calculated as 2000 hands empty. This is mainly used in the outer disk. Because of the existence of hedging, the inner disk is generally cleared, and there are few net positions.
