1, k line, d line, j line. When the KDJ index is above 80, it is overbought, the stock price will fall at any time, and 50-80 is a strong market. The fluctuation during this period is normal.

Below 2.50 is the drowning market, indicating that the stock price does not rise, below 20 is oversold, and the stock price rebounds at any time. In addition, the third line of KDJ is above 80, and the high position has a downward dead fork, which is theoretically a selling signal, and the upward gold fork below 20 is a buying signal. Technical indicators are only for reference.

3. For stock speculators, it is necessary to combine the fundamentals of the market and stocks. The stochastic index considers the highest price and lowest price in the calculation period and the random amplitude in the stock price fluctuation, so it is considered that the stochastic index reflects the stock price fluctuation more truly and its prompt function is more obvious.

KDJ, also known as stochastics, represents the strength of the price trend and 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. K is a fast indicator and d is a slow indicator. When the K-line breaks through the D-line upward, it means that it is an upward trend, which means that it can be bought, and when the K-line breaks through the D-line downward, it means that it can be sold.

The advantages of 1 and KDJ indicators are: the indicators are very sensitive, suitable for short-term operation and high accuracy under normal circumstances.

Disadvantages are: indicators are too sensitive, often sending out buy and sell signals prematurely, and indicators will be passivated in extremely strong markets and extremely weak markets, making investors at a loss, buying and selling prematurely, and causing operational errors.

2. Stochastic indicator KDJ is usually a statistical system used for stock analysis. According to the statistical principle, the immature random value RSV of the previous calculation period is calculated by the highest price, lowest price and closing price of the previous 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.
