For example, the turnover of a stock today is10 billion, which may be 500 million for the buyer, 500 million for the seller, 800 million for the buyer, 300 million for the buyer and 700 million for the seller. There is no need to stipulate that the buyer must be 500 million and the seller must be 500 million. Stock turnover is the sum of buying and selling. The volume of stock refers to the total number of stock transactions, in which the number of transactions should be distinguished. For example, there are 1 000 transactions a day, each with 500 shares, so the total number of transactions is 1 000 transactions, with 500,000 shares.

1. Stock turnover refers to the total amount of transactions between buyers and sellers. This sentence does not mean 50% each. This is a combination of each buyer and seller. Stock, we need systematic study to do a good job in every stock, no matter what market.

2. Why is the sum of buying and selling not equal to the trading volume? At present, the disclosure of transactions in Shanghai and Shenzhen stock exchanges refers to the disclosure of the top three highest buying prices and the top three lowest selling prices. This is real-time transaction disclosure. After the transaction, it is included in the transaction volume, and if it is not, it is not included in the transaction volume. So the sum of buying and selling has nothing to do with the volume. How do you judge which transactions are completed by buying or selling? Here is a way: in the current stock computer analysis system, there are "external quotation" and "internal quotation" disclosures, which are included in the "external quotation" and "internal quotation" of trading with sellers. The buyer's transaction. In this way, we can distinguish which transactions are completed by the buyer and which transactions are completed by the seller.

3. Outer disk and inner disk often appear in technical analysis systems. Entrust the seller's transaction into the "external asking price" and entrust the buyer's transaction into the "internal asking price". "Outer disk" and "inner disk" add up to volume. Because the commission of the seller's transaction is included in the external quotation, if the external quotation is large, it means that most of the selling price has been received, which means that the buying trend is strong; If the internal quotation is too large, it means that most of the purchase price is willing to sell, which means that the seller has more power. If the internal and external quotations are roughly similar, the trading capacity is equal.

4. For example, the quotation of a stock is disclosed as follows: the purchase price of Party A is 25.07 yuan, the number of consignments is 27, the selling price of Party B is 25. 1 yuan, and the number of consignments is 562. Because the buying price and selling price can't match at this time, the stock is waiting for a deal, and the sale is in a stalemate. At this time, if the on-site buying is active and the buying price of 25. 17 yuan is suddenly quoted, then the stock is traded at the price of 25. 17 yuan, which is the "external quotation". Or, at this time, if the selling pressure in the market is heavy, the stock price drops to 25. 10 yuan, and a list of 25.07 yuan is suddenly quoted, then the stock is traded at 25.07 yuan, and the list with buying transactions will be classified as "internal market".
