The so-called call auction is to input the stock price according to the closing price of the previous day and the forecast of the stock market on the same day before the opening of the day, input all orders placed by the computer host within call auction time, and calculate the price of the maximum trading volume according to the principle of price priority and time priority. This price is called the clinch a deal price in call auction, and this process is called call auction.
After 9: 25, you can see the transaction price and quantity of each stock in call auction. Sometimes a stock can't be traded because the price given by the buyer is lower than the price given by the seller, so the trading price column of this stock is empty after 9: 25. Of course, there are also companies that stop trading for a period of time because they want to release news or hold a general meeting of shareholders, so the transaction price column of the company's stock in call auction is also empty.
Because call auction clinched a deal at the price of the largest turnover, so for ordinary investors, in call auction time, as long as the price of the stock entering the market is higher than the actual transaction price, you can clinch a deal. Of course, if you buy at the daily limit or sell at the daily limit, priority will be guaranteed. Therefore, if retail investors want to have the priority to buy shares in call auction, they can usually bid higher to get the trading priority, because the trading price in call auction is lower. In addition, the number of stocks bought by retail investors will not be very large, which generally will not affect the call auction price of stocks.
