What is rsi on a chart

The Relative Strength Index (RSI) is a technical indicator that measures the speed and magnitude of recent price changes in a security. It is displayed as an oscillator on a chart, ranging from 0 to 100. The RSI can help identify overbought or oversold conditions, as well as potential trend reversals or corrective pullbacks. Traditionally, an RSI reading of 70 or above indicates an overbought situation, while a reading of 30 or below indicates an oversold condition.
