KD index and KDJ index are the same. You can point out KDJ and KD at the same time in your own software, and you will know that KD is the same, but there is one more J. This J is the sum of KD data, which is generally ahead of KD.

The KDJ index, also known as stochastics, was first proposed by Dr. George Lane. This is a very novel and practical technical analysis index. It was first used in the analysis of futures market, and then widely used in the short-term trend analysis of stock market. It is the most commonly used technical analysis tool in futures and stock markets. Stochastic indicator KDJ is usually a statistical system used for stock analysis. According to the statistical principle, the immature random value RSV of the last calculation period is calculated by the highest price, lowest price and closing price of the last calculation period in a specific period (usually 9 days, 9 weeks, etc.). ) and the proportional relationship between them. Then, according to smma method, the K value, D value and J value are calculated, and the stock trend is judged by drawing.
