Optimal parameter setting of skdj index
The best setting of KDJ index parameters is generally (6.3.3), that is, the change of D value and J value between three trading days in five trading days. In fact, the default setting of trading software is 9, which causes some problems. The passivation phenomenon is extremely serious, which is invalid. In ancient books, 9 is the pole, and the parameters indicate the change in this position. However, in actual trading, the normal two-week trading day is 10 trading day, which is one less, so it is understandable that the parameters are passivated and the errors are formed. On the contrary, if the parameter is changed to 5, this is exactly the change of the market in a week.

1 and KDJ index, which are called random in Chinese, are novel and practical technical analysis indicators. It is 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.

2. Stochastical skdj is usually a statistical system for stock analysis. According to the statistical principle, the immature random value RSV in the last calculation period is calculated from the highest price, lowest price and closing price of the last calculation period in a specific period (usually 9 days, 9 weeks, etc.). ) and its proportional relationship. Then, according to smma method, calculate K value, D value and J value, and judge the trend of the stock by drawing a chart.

3. The Chinese name of 3.KDJ Index, also known as stochastics, originated from the futures market and was initiated by George Lane. Random KDJ first appeared in the form of KD index, which was developed on the basis of William index. The KD index only judges the phenomenon of overbought and oversold, while the KDJ index combines the concept of moving average speed to form a relatively accurate trading signal basis. In practice, K-line, D-line and J-line together form KDJ index. In the design process, KDJ index mainly studies the relationship between the highest price, the lowest price and the closing price, and integrates some advantages of momentum concept, intensity index and moving average. Therefore, it can judge the market quickly, quickly and intuitively, and is widely used in the short-term trend analysis of the stock market. It is the most commonly used technical analysis tool in futures and stock markets.
