For example, the settlement price of a soybean contract yesterday was 4000 yuan per ton. In call auction today, there are more than 65,438+000 hands out of 4065,438+000 hands, and 65,438+000 hands out of 4000 hands. It's impossible to make a deal. If someone also hangs 65,438+00 lots at 4065,438+00, then today's opening price is. Of course, if it is 4020, someone will open 200 more hands. 4020 no one hangs the liquidation order, and the opening price is still 40 10. If someone hangs a liquidation order at 4020, the opening bid auction will be at 4020.

Call auction orders must be opened and closed at the opening price. Then the number of lots is screened on the basis of price, and the number of lots is the first.
