The Relative Strength Index (RSI) is a cornerstone technical indicator in forex trading, helping traders gauge price momentum and potential reversal points. This beginner-friendly guide breaks down a practical RSI strategy while optimizing it for modern trading conditions.
How RSI Works: Core Mechanics Explained
RSI oscillates between 0-100, with key thresholds:
- Overbought zone: 70+ (potential price drop)
- Oversold zone: ≤30 (potential price rise)
- Neutral zone: 40-60 (consolidation)
The standard 14-period calculation can be adjusted for different trading styles. Shorter periods (e.g., 7) increase sensitivity, while longer periods (e.g., 21) smooth out fluctuations.
