What's the difference between KD and KDJ in stock analysis?

What's the difference between 1.KD and KDJ in stock analysis?

KD is a random index and KDJ is a random index, both of which are very practical technical analysis indicators.

KDJ index has one more J line than KD index. This j is the sum of KD data, generally before KD. The KD values of the two lines are the same, and the J value =3* the K value of the day -2* the D value of the day.

Second, KD index

Stochastics (KD) is suitable for technical analysis of short and medium-term stocks.

Apply rules:

1, the values of k and d are always between 0 and 100. D value > 80, the market is overbought; D value 2, when k value >; D value, the trend is rising, so when the K line breaks through the D line, it is a buy signal; When the value of k is 3, and the intersection of K line and D line is between 70 and 30, the transaction is more reliable. If KD gold fork occurs below 20, it is the best buying point; If KD death crossover occurs above 80, it is the best selling point.

Third, KDJ indicators.

The Chinese name of KDJ index is stochastic index, which 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.
