The kdj line is the three lines of k, d, and j of the stochastic indicator.

The Chinese name of the kdj indicator is the stochastic index, which originated from the futures market.

The application rules of kdj indicator: kdj indicator is three curves, and the value of j indicator is.

First, consider the value of kd. The value range of kd is 0~100, and the rest is the wandering area.

According to this division, if KD exceeds 80, you should consider selling. It is easy to cause losses if you operate entirely according to this method.

Second, consider the shape of the kd indicator curve. The conclusion is more reliable.

Third, consider the intersection of KD indicators. There are many other conditions attached.

Take k crossing d from bottom to top as an example: k crossing d above is a golden cross, which is a buy signal. The lower the better.

The second condition is the number of intersections with d. Sometimes in the low position, K and D have to cross back and forth several times. The minimum number of crossovers is 2, and the more, the better.

The third condition is the position of the intersection relative to the low point of the KD line, which is often said to be "much more reliable than crossing it when D is still falling."

Fourth, consider the deviation of the kd indicator. When kd is at a high or low level, if there is a deviation from the stock price trend, it is a signal to take action.

Fifth, the j indicator value exceeds 100. and below 0, both belong to the abnormal area of ??price. Greater than 100 means overbought, and less than 0 means oversold.
