What is a Relative Strength Index (RSI)?

Relative Strength Index (RSI) is a technical indicator that is represented as a number between 0 and 100.

It analyzes whether a security’s price movement is a result of it being overbought or oversold. RSI can also be used to identify assets that are primed for a trend reversal or correction in price. A security is generally considered oversold when the RSI is below 30, and overbought when the RSI is above 70.
