Retail investors can bid by phone, as long as the match is successful. In call auction, if the declared prices are the same, then whoever declares early will clinch a deal first, and the number of declared lots is not the principle of bidding. Some investors mistakenly believe that "bookmakers can make a deal first when they declare a large number of hands, and small and medium-sized retail investors can't make a deal when they declare a small number of hands" is unfounded.

Extended data:

Call auction in the stock market refers to a bidding method in which the exchange collectively sets the price after accepting the trading declaration instructions of investors for a period of time. In the A-share market, the transaction price in call auction is the price at which the market turnover is within the effective price range.

Call auction is the principle of price first and time first. When the price of the order is the same as that in call auction, the Committee will complete the transaction. If the payment price of the investment order is higher than that of call auction, the transaction will also end. On the other hand, if the investment order is lower than that of call auction, the transaction will be concluded.

Call auction can see the enthusiasm of investors before the stock or market opens. If the enthusiasm is higher, call auction will pay more and the price will be higher. On the other hand, if the heat is low, call auction will sell more orders and the price will be lower. When the normal volume is higher than the volume of 1.6 18 times, it means the volume of call auction.

Under normal circumstances, if a stock is in an upward trend, the previous transaction is still in an upward trend, and the amount paid for the transaction is relatively large, and the amount paid by call auction on that day is still very large. Then there is a great possibility that this stock will open higher and rise later. On the other hand, if a stock is in a downward trend, the previous transaction is in a downward trend and a large number of orders are sold at the close. On that day, call auction's sales volume was still very large, so this stock is likely to open lower and then fall.

Generally speaking, call auction is a bidding method, which has an impact on the subsequent stock or disk trend. But there is no perfect investment method and interpretation method in the investment market. All need to be combined with other market indicators, market environment and individual stocks for reference.
