The red and green columns above indicate the number of unmatched transactions, in which red indicates the unfinished purchase orders in call auction and green indicates the unfinished sales orders; The red and green columns below represent the volume of virtual matching, in which red represents the active buying volume of matching and green represents the active selling volume of the transaction.
The system uses red and green columns to identify the number of participants in call auction. The red column represents the consignment quantity, and the green column represents the consignment quantity. The length of this column represents the consignment quantity. A long column indicates a large number, and a short column indicates a small number.
Call auction is between 9: 15-9:25 every trading day. Investors can predict the stock price trend of the day according to yesterday's closing price, and then place an order. Among them, 9: 15-9:20 can be entrusted and revoked; 9:20-9:25 can only be entrusted and cannot be revoked; From 9: 25 to 9: 30, you can't hold orders or cancel orders, and the entrusted orders are temporarily stored in the host computer.
Therefore, call auction only accepts the entrustment, which does not mean the real transaction, so the red and green columns will change at any time. The red and green columns in call auction can only reflect the bidding status before the opening, so they can't reflect the trend of the day.
The situation in call auction is related to the opening of the day and the operation of the stock price. Call auction is divided into three parts, one is the price change in call auction; The second is the number of matches; The third is mismatch. The price in call auction is at the top of the bidding chart, and the market has a strong willingness to buy. The price will be directly sealed, and the opening price will be a word board. Weak willingness to buy will be lower than yesterday's closing price, and it will go down all the way until the opening price is determined. Of course, the market is not optimistic about the day's market, and the bidding is also high and low, opening lower than yesterday's closing price. Sometimes the main force will use call auction to play tricks, first make an offer and then suddenly withdraw the order, so the price will go down. Therefore, it is necessary to consider the intention of the main force through call auction, combined with the commission sales of call auction to judge.
Consignment quantity is divided into matched consignment quantity and unmatched consignment quantity. Mismatched consignment is an upside-down red-green column in the middle of the call auction diagram. The inverted red column is the number of unmatched delegates, and the green column is the number of unmatched delegates. The more upside-down red columns, the stronger the market's willingness to buy. On the contrary, it shows that the market is willing to sell. The corresponding consignment quantity is in the lower part of the call auction chart. The more red bars, the longer the bars, and the more optimistic the market is about the market. On the contrary, the market is not optimistic about the market that day.
