Relative Strength Index (RSI) Indicator

The relative strength index (RSI) is a momentum indicator used in technical analysis. RSI measures the speed and magnitude of a security's recent price changes to detect overbought or oversold conditions in the price of that security. The RSI is displayed as an oscillator (a line graph) on a scale of zero to 100.

RSI readings below 30 signal buy opportunities, indicating the asset is undervalued. Conversely, RSI readings above 70 signal sell opportunities, suggesting the asset is overvalued. A value of 50 signifies a balance between bullish and bearish positions or a neutral stance.
