Go-kart cycle (KDJ) is a commonly used technical analysis index, which is called "random fluctuation index". It is mainly used to study the price fluctuation of financial markets such as stocks, futures and foreign exchange, and to help investors judge the overbought or oversold state of the market in order to make trading decisions.
Go-kart staging consists of three curves: K line, D line and J line. Their calculation formulas and range of values are as follows:
1.k line: K= 100-(RSV/SV), where RSV is an immature random value and SV is a saturated random value.
2.D line: D=20-(3K-2D)/3, and D line is the average value of K line to smooth fluctuations.
3.J line: J=3K-2D, which is used to judge the market trend.
