Sometimes, if a security has not been traded for several days, the stock exchange will put forward a guiding price according to the price trend of the securities entrusted by customers as the opening price after trading. At present, the opening prices of stocks in China, Shanghai and Shenzhen stock exchanges are generated by the computer hosts of the exchanges in the way of call auction.

The principle of generating opening price
The opening price of the futures market is generated by call auction, and the principle of call auction's opening price is different from the closing price principle in normal trading, so in some cases, it is impossible to make a deal if the declared buying price is higher than the opening price or the declared selling price is lower than the opening price.
The opening price is call auction, and its principle is that the consignment price of a stock in the consignment note sent by buyers and sellers to Shenzhen and Shanghai between 9: 00 and 9: 25 is the same, but it is worth noting that this "consistent share price" refers to the "consistent share price" that can match the largest amount in a single transaction, and the consistent consignment price of buyers and sellers is not necessarily the highest price.
The "call auction" generated between 9: 00 and 9: 25 does not implement the principle of "time priority" implemented by "continuous bidding" when the entrusted prices are consistent after 9: 30.
