What Is Relative strength index (RSI)?

The Relative Strength Index (RSI) is a popular momentum indicator used in technical analysis to measure the strength of a security’s price action. It compares the magnitude of recent gains to recent losses, in order to determine overbought or oversold conditions, and potential buying or selling opportunities.

The RSI is calculated as a ratio of average gains to average losses, and is represented as a value between 0 and 100. Values above 70 are considered overbought and may indicate a potential sell opportunity, while values below 30 are considered oversold and may indicate a potential buy opportunity. The RSI can be used for various time frames and for multiple securities, including individual stocks, bonds, commodities, and currencies.
