It is KDJ, it is the stock K line and the three lines in the bottom chart of trading volume

The KDJ indicator is also called the stochastic indicator, which is a quite novel and practical technical analysis indicator. , it was first used in the analysis of the futures market, and later was widely used in the short- and medium-term trend analysis of the stock market. It is the most commonly used technical analysis tool in the futures and stock markets.

1. The K and D values ??are always between 0 and 100. When D is greater than 70, the market is overbought. When D is less than 30, the market is oversold.

2. When K is greater than D, it shows that the trend is upward. Therefore, when the K line breaks through the D line, it is a buying signal. When the D value is greater than the K value, the trend is downward, and when the K line falls below the D line, it is a sell signal.

3. The KD indicator can not only reflect the degree of overbought and oversold in the market, but can also send out buying and selling signals through cross breakthroughs.

4. The KD indicator is not suitable for stocks with small circulation and inactive trading, but the KD indicator has extremely high accuracy for large-cap stocks and popular large-cap stocks.

5. When the stochastic indicator deviates from the stock price, it is generally a signal of a trend change.

6. The rising or falling speed of K value and D value weakens, and the slope tends to be gentle, which is an early warning signal for short-term trend change.
