Announce the positions on the exchange every day, and the top 20 positions are distributed. You can go to a futures company or four exchanges to look for it. Your screenshot is the volume of transactions, and the amount of positions are two concepts. Open positions are transactions that have not been opened, and are calculated bilaterally in China. For example, there are 1 individuals holding 100 lots of stock index bulls, and there are several people holding 100 lots of stock index bears on their opponents' plates, and they have not closed their positions, so the position is 200 lots. If no one has been trading in the market and the volume is zero, closing a position and holding a position are different concepts.
