Key Takeaways
- The RSI (Relative Strength Index) is a momentum oscillator measuring price movement speed on a 0–100 scale.
- Readings >70 signal overbought conditions (potential downtrend); <30 indicate oversold (potential uptrend).
- Divergences between price and RSI hint at trend reversals.
- Combine RSI with price action, market structure, and other indicators for robust signals.
- Adjust the RSI period (default: 14) for different trading styles—shorter for day trades, longer for swings.
What Is the RSI Indicator?
The Relative Strength Index (RSI), developed by J. Welles Wilder Jr., quantifies momentum by comparing recent gains to losses over a set period (typically 14). It helps traders spot overbought/oversold levels and potential reversals.
How It Works
- 70+: Overbought → Possible pullback.
- 30–: Oversold → Possible rebound.
- 30–70: Neutral momentum.
