Suppose A wants to buy 10 soybean contracts, and B wants to sell 10 soybean contracts, then the two transactions will be completed.

If both positions are opened at the same time, and the sales contracts are of the same variety and quantity, it is called double opening. Double opening means that both positions are opened at the same time, so the position is increased.

If there is a lot of selling, that is, B wants to sell 12 lots, but A only buys 10 lots, so there is also a C who wants to buy 2 lots to close the position. In the same way, it is a short opening.
