What is the RSI indicator?

RSI is short for Relative Strength Index.
It is mainly used to evaluate overbought or oversold conditions of a stock market. It is a momentum indicator used in technical analysis.
We can learn the overbought and oversold conditions of a token by evaluating recent price change range.

This technical indicator is mainly used to calculate the rising and falling of price by considering several unstable elements of asset price (the number of days of price change, and the magnitude of price change). So many investors use RSI to predict entry and exit points.
