Only buying and selling can clinch a deal, and the same bulls always correspond to the same shorts. The buyers and sellers of open contracts are equal, and domestic positions are calculated according to the total number of buyers and sellers. If both the buyer and the seller are new positions, two contracts will be added; If one party opens the position and the other party closes the position, the position remains unchanged; If the buyers and sellers close their positions, the positions will be reduced by 2 contracts. When the next opening quantity is equal to the closing quantity, the positions held will remain unchanged.
