What is RSI (Relative Strength Index)?
IndicatorsBeginner
RSI is a momentum oscillator that measures the speed and magnitude of price changes on a scale of 0-100. Above 70 suggests overbought conditions; below 30 suggests oversold. RSI divergence — where RSI moves opposite to price — is one of the strongest reversal signals in technical analysis.
