Relative strength index. It is an overbought and oversold indicator, which is used to measure and analyze the rise and fall of futures or stocks. The RSI indicator analyzes the intention and intensity of market trading by comparing the average closing increase and the average income decrease in a period of time, thus analyzing the future market trend. There are three RSI indicators, in which RSI 1 represents the relative strength on the 6th, RSI2 represents the relative strength on the 2nd, and RSI3 represents the relative strength on the 24th. Generally speaking, RSI takes 50 as the center line, with more than 50 as a long market and less than 50 as a short market.

KDJ index reflects the comparison between buyers and sellers in the market with real price fluctuations, and only considers the latest highest price, lowest price and closing price in the calculation process. Its characteristic is that it can judge the market quickly and intuitively.
