Relative Strength Index (RSI) | ChartSchool | StockCharts

What Is the Relative Strength Index (RSI)? The RSI, a momentum oscillator developed by J. Welles Wilder, measures the speed and change of price movements. The RSI moves up and down (oscillates) between zero and 100. When the RSI is above 70, it generally indicates overbought conditions; when the RSI is below 30, it indicates oversold conditions.
