1, the KDJ index parameter of daily K-line is selected from one of the following values, all of which have good use effects: (6,3,3), (18,3,3), (24,3,3). Investors can flexibly set the parameters of this indicator according to different stocks and different time periods.
2. The sensitivity to price fluctuation has been strengthened, and its change frequency is very high, which is suitable for short-term customers to find trading points. Generally speaking. Every crossing of the three lines of KDJ in the overbought and oversold area will probably become an important operation time.
3. The false signal generated by price fluctuation is eliminated to a greater extent, and it is a better choice to find the midline buying point or midline selling point of the price.
In addition, setting kdj index with (24, 3, 3) as the parameter can eliminate the false signal caused by price fluctuation to a greater extent, and it is also a better choice to find the midline buying point or midline selling point of the price. Therefore, (6, 3, 3), (18, 3, 3) and (24, 3, 3) as the kdj indicators of daily K-line will have a good effect, and traders can also set the parameters of an indicator more flexibly according to different stocks and different time periods.
The full name of KDJ is stochastic index, which was founded by Dr. george ryan in the United States. Its comprehensive momentum concept, strength index and the advantages of moving average are also a common technical analysis tool in European and American securities and futures markets. Stochastics's design thought and calculation formula originated from William's (W%R) theory, but it is more valuable than W%R index. W%R index is generally limited to judging the overbought and oversold phenomenon of stocks, while stochastics combines the idea of moving average to judge the buying and selling signals more accurately.
B, random indicators are generally used in the statistical system of stock analysis. According to the principle of statistics, the immature random value RSV of the last calculation period is calculated by the highest price, the lowest price and the closing price of the last calculation period in a specific period (usually 9 days, 9 weeks, etc.). ) and the proportional relationship between them, and then calculate the k value, d value and j value according to smma method, and judge the stock trend by drawing. KDJ (stochastic indicator): It is an extended tool of William indicator, which reflects the strength of price trend and the state of overbought and oversold by calculating the fluctuation between the highest price, the lowest price and the closing price in a certain period.
