(A) the use of DDX
The red and green bars of DDX indicate the percentage (estimated value) of the net amount of big orders bought that day, the red bars indicate the amount of big orders bought, and the green bars indicate the amount of big orders sold. DDX 1 is the proportion of the smooth cumulative value of the net large orders bought on the 60th day (parameter p 1), and DDX2 and DDX3 are the 5th day (parameter p2) and 65438+.
Usage:
(1) If the red and green bars are red on that day, it means that large orders were bought in large quantities on that day; On the other hand, if the red and green bars are green on that day, it means that large orders are sold in large quantities.
(2) The third line continued to rise, the main force actively bought, and the stock price continued to rise. (3) The continuous downward trend of Line 3 indicates that the main force continues to sell.
(4) DDX can be sorted from large to small in the dynamic display card, and short-term strong stocks can be selected. The following actual case analysis:
(Case 1: Zhongcheng Shares) When the share price turns from weak to strong.
DDX is an indicator to track major large order transactions. When the net purchase of large orders exceeds the net sale of large orders, there will be obvious red columns, and vice versa. Although DDX and price fluctuation are not perfect positive correlation, stocks with obvious inflow of large single funds generally have a higher probability of rising, and stocks with obvious sales of large single funds have a higher probability of falling in the afternoon. When the trend of continuous green columns ends, red columns appear (in recent trading days, the more red columns or continuous red columns can explain the problem), which is often the time when short-selling funds are obviously weakened and many main funds begin to enter the market, and it is also the turning point for stock prices to turn from weak to strong.
This is the case with the following China stocks. 65438+1October 20-26, after the net sale of large single funds and the stock price fell for six consecutive trading days, the net inflow of large single funds began to appear on the 27th, and the red column was obviously enlarged on the 28th, and the DDX three-line gold fork went up, showing a long position, and the stock price was obviously strong in the short term.
