The calculation method of KDJ index: The calculation of KDJ is relatively complicated, first of all, the RSV value of the period (n days, n weeks, etc.) must be calculated, that is, the immature random index value, and then the K value, D value, J value, etc. Take the calculation of daily KDJ value as an example,
The calculation formula is: N-day RSV= (CN-LN) ÷ (Hn-Ln) ×100, where Cn is the closing price on the NTH day; Ln is the lowest price in n days; Hn is the highest price in n days. RSV values always fluctuate between 1-100.
Secondly, K value and D value are calculated: K value of the day =2\/3× K value of the previous day +1\/3× RSV of the day;
D value of the day =2\/3× D value of the previous day +1\/3× K value of the day; If there is no K value and D value of the previous day, it can be replaced by 50. Take KD line with 9-day period as an example. First, we must calculate the RSV value of the last 9 days, that is, the immature random value.
The calculation formula is: 9-day RSV= (C-L9) ÷ (H9-L9) ×100, where C is the closing price of the 9th day; L9 is the lowest price within 9 days; H9 is the highest in 9 days.
K value =2\/3× previous day K value +1\/3× current day RSV; D value =2\/3 x previous day K value +1\/3 x current day RSV
If there is no K value and D value of the previous day, it can be replaced by 50 respectively. It should be noted that the smoothing factors 1\/3 and 2\/3 in the formula can be artificially selected, but it has been fixed to 1\/3 and 2\/3 by convention. In most stock market analysis software, the smoothing factor is already set to 1\/3 and 2\/3 and does not need to be changed. In addition, KD is usually introduced with a J indicator.
The formula for calculating J indicator is: J= 3D-2k
In fact, the essence of J is to reflect the degree of divergence between K and D values, so as to find the head or bottom ahead of the KD value. The J-value range can exceed 100. J indicator is an auxiliary indicator, the earliest KDJ indicator has only two lines, that is, K line and D line, the indicator is also known as KD indicator, with the development of stock market analysis technology, KD indicator gradually evolved into KDJ indicator, thereby improving the ability of KDJ indicator to analyze the market.
In addition, in some important stock market analysis software, the K, D and J parameters of the KDJ pointer have been simplified into only one, that is, cycle number (such as day, week, month, etc.). Moreover, with the development of stock market software analysis technology, investors only need to master the basic principle and calculation method of the formation of KDJ, and there is no need to calculate the value of K, D and J. More important is the use of KDJ indicators to analyze, analyze the stock market.
Detailed use can refer to the relevant books, at the same time combined with a simulation plate exercise for a period of time, so that you can quickly and effectively master the knowledge, the current Niu stock treasure simulation stock is not bad, there are a number of indicators guidance, each indicator has a description of how to use, the use of certain help, hope to help you, I wish happy investment!
