Only buying and selling can clinch a deal, and the same bulls always correspond to the same shorts. Who else sold him the long position? For example, there are only two of us in this market. I buy 10 lot. You sell 10 lots, and I can only close the deal if your price is right. After the transaction, I held more than 10 lots. Your position is 10. The total market position is 20 lots. If the third person comes to the market, he sells 65,438+00 lots. If we don't have an order, he won't make a deal. If you only buy 10 and trade with him, your 10 hand will be changed to his, and the market will still hold 20 hands.

Open position, also known as short position or open position, refers to the quantity of a commodity futures contract that has not been hedged and delivered in kind after buying or selling.

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 buyers and sellers are new positions, 2 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.
