Random indicator KDJ is a point formed by calculating the highest price, lowest price and closing price, and connecting the obtained K value, D value and J value with countless such points to form a complete KDJ indicator that can reflect the price fluctuation trend. It is a technical tool that mainly uses the real amplitude of price fluctuation to reflect the strength of price trend and the phenomenon of overbought and oversold, and sends out buying and selling signals before the price rises or falls. In the design process, the relationship between the highest price, the lowest price and the closing price is mainly studied, and some advantages of the concept of momentum, power index and moving average are also integrated, so the market can be judged quickly, quickly and intuitively.

KDJ (stochastic indicator 9-3-3):

D & gt80 overbought, D.

J-index method for judging the bottom: when J continuously drops to a value below 0, that is, a negative number, an important bottom will appear in cooperation with the important moving average. Generally, it is better to be above-10. Another important factor is that you must leave the 5-day moving average above 10%. Only in this way can you basically guarantee that there is room for the stock to rebound.

J-indicator judgment method: when the J-indicator continuously rises to the value above 100, it will run in the opposite direction at any time. But in a bull market, it is relatively simple to judge the bottom of the J index, and it takes a lot of time to judge the head. If it continues to rise, there will inevitably be a callback above 100, and the judgment is based on the fact that the stock price is more than 5% away from the 5-day moving average10.

Steady profit without loss method: use weekly KDJ index to find stocks and intervene; As a newly listed new stock, it is relatively simple to judge. As long as the KD indicator is found to form a secondary upward golden cross on the weekly line, the strength is generally not small.

Defect: the indicator will show signs of passivation after continuous rise or fall, that is, the indicator will continue to rise and fall at a relatively high level.
