What is the Relative Strength Index (RSI)?
The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of price movements in forex trading. Operating on a scale from 0 to 100, RSI helps traders identify:
- Overbought conditions (RSI > 70)
- Oversold conditions (RSI < 30)
Developed by J. Welles Wilder Jr., RSI calculates average price gains/losses over a 14-day period (default setting).
Key Features:
- Momentum Tracking: Gauges price change velocity.
- Reversal Signals: Flags potential market turns.
How RSI Enhances Your Forex Trading Strategy
1. Identify Market Extremes
- Overbought (RSI > 70) → Potential sell signal
- Oversold (RSI < 30) → Potential buy signal
2. Spot Divergence
- Bullish Divergence: Price makes lower lows, RSI makes higher lows → Upward reversal likely.
- Bearish Divergence: Price makes higher highs, RSI makes lower highs → Downward reversal likely.
3. Optimize Entry/Exit Points
RSI crossovers (e.g., RSI rising above 30 from oversold) refine timing.

Optimal RSI Settings
| Setting | Recommended Use |
|---------|-----------------|

Practical Tips for Using RSI
Combine with Other Indicators
- Pair RSI with Moving Averages or MACD to confirm trends.
Adjust Thresholds
- Use 80/20 for volatile markets to reduce noise.
Multi-Timeframe Analysis
- Compare RSI on hourly/daily charts for alignment.
Top RSI Trading Strategies
1. Overbought/Oversold Reversal
- Buy when RSI crosses above 30.
- Sell when RSI crosses below 70.
2. Divergence Trading
- Enter trades when price and RSI diverge (e.g., bullish divergence → long position).
3. Swing Rejection
- Watch for RSI to reject extremes (e.g., dips below 30 then rebounds quickly).
Real-World RSI Examples
