Formula name: ZJQDL；;

Formula description: capital driving force;

Super B: = L2 _ Amo (0,2)/10000.0;

Big B: = L2 _ Amo (1, 2)/10000.0;

B: = L2 _ Amo (2,2)/10000.0;

Small b: = L2 _ Amo (3,2)/10000.0;

Super s: = L2 _ amo (0,3)/10000.0;

Big S: = L2 _ Amo (1, 3)/10000.0;

S: = L2 _ Amo (2,3)/10000.0;

Small s: = L2 _ amo (3,3)/10000.0;

Net inflow: (super B+ big B+ medium B+ small B)- (super S+ big S+ medium S+ small S);

Bulk net inflow: (Super B+ Big B)- (Super S+ Big S).

The full name of the index is "net inflow and outflow index of main funds". The logic of the index is that the capital of the main force is much larger than that of the retail investors. Therefore, the average volume and average volume of the main orders are naturally larger than those of retail investors.

Net inflow of main funds = main inflow-main outflow.

Master Doc = Super Doc+Large Doc.

The standard definition of oversize order is more than 2000 lots, or the single quantity is more than 654.38+00000.

Standard definition of bulk order: 600-2,000 lots, or a single amount of 300- 1 10,000.

Investors can predict the trend of individual stocks according to the changes of some technical indicators. For example, at the same time, investors can predict the trend of individual stocks according to the size of trading volume and the inflow and outflow of main funds, among which the inflow and outflow of main funds is a more common method. When the main capital inflow is greater than the main capital outflow, the main capital inflow is positive, that is, the main capital net inflow; When the main capital inflow is less than the main capital outflow, the main capital inflow is negative, that is, the net outflow of main capital. That is, the net inflow of main funds means that the main force buys more and sells less to jointly promote the stock price rise, which is a buying signal. That is, the net outflow of main funds means that the main force buys less and sells more, which leads to the stock price falling, which is a selling signal. However, the net inflow of main funds is positive, which generally means that the main force is suppressing stock prices, washing dishes and taking the opportunity to raise funds at a low level. After raising funds, the stock price may rise, and investors can do more. However, the actual net inflow of funds is very small, which generally means that the main force is in the dark. Investors should be cautious and can choose to wait and see. Investors can use the main capital inflow and outflow to analyze individual stocks together with other technical indicators for comprehensive consideration.
