How to inquire about the inflow and outflow of futures varieties?
The simplest method is to subtract the number of hands in the inner disk from the number of hands in the outer disk and multiply it by the average transaction price of the day to get the net flow of funds for the day. If the outer disk is larger than the inner disk, it is a net inflow of funds, and vice versa.

Entrust the transaction into the "outer disk" at the selling price; Entrust the transaction into the "inner disk" at the purchase price.

The external market is also called active buying, that is, the accumulated trading volume at the selling price; Internal selling is also called active selling, that is, the cumulative trading volume at the purchase price. The outer disk reflects the willingness to buy actively, and the inner disk reflects the willingness to sell actively.

Inner disk: buy one, buy two, buy three price transactions, and add the statistics of the number of buy transactions to the inner disk.

Outer disk: a transaction that is concluded at the price of selling one, selling two and selling three. Statistics on the number of sales transactions are added to the external disk.

The two data of inner disk and outer disk can be used to judge the strength of buying and selling rights. If the number of external disks is greater than the number of internal disks, the buyer is stronger; If the number of inner disks is greater than the number of outer disks, the strength of the seller will be stronger.

Extended data:

Dealers can cheat by using the number of outer and inner disks. The following situation was found:

1. After a long period of decline, the stock price is at a lower price, and the turnover is extremely shrinking. Since then, the volume of transactions has been moderate and heavy, and the external market has increased on that day, which is greater than the internal market, and the stock price will probably rise.

2. After a long time, the stock price rises, the stock price is at a high price, and the transaction volume is huge. If the number of internal disks is larger than the number of external disks, the stock price may fall.

3. In the process of stock price decline, it is often found that the external disk is large and the internal disk is small. This situation does not mean that the stock price will definitely rise. Because sometimes the dealer will use a few orders to hit the stock price to a lower position.

4. In the process of stock price rising. At this point, investors think that the stock price will fall, and they sell the stock at the purchase price one after another, and the banker can hold the order step by step accordingly.
