RSI (Relative Strength Index)

RSI (Relative Strength Index) is a momentum oscillator that measures the speed and magnitude of price changes on a scale of 0 to 100. Readings above 70 traditionally indicate overbought conditions, where an asset may be due for a pullback. Readings below 30 indicate oversold conditions, where a bounce may be imminent. The default period is 14, but traders adjust based on their timeframe and strategy.

RSI was developed by J. Welles Wilder and introduced in his 1978 book. The formula compares the magnitude of recent gains to recent losses over the lookback period, producing a normalized value between 0 and 100. Beyond the 70/30 overbought/oversold lines, traders also watch for RSI divergence (when price makes a new high or low but RSI does not confirm), centerline crossovers (RSI moving above or below 50 signals momentum shifts), and range shifts (RSI tending to stay in specific zones during trending vs. ranging markets).

For example, if EUR/USD is at 1.0950 and RSI is at 82 (overbought) while making lower highs on the indicator even as price makes higher highs, that is bearish divergence. A trader might enter a short at 1.0945 with a stop above recent swing high at 1.0980 (35 pips) and target at 1.0880 (65 pips), a 1:1.9 risk-reward. The RSI signal gives a quantifiable way to identify momentum exhaustion that pure price analysis might miss.
