Gartley Pattern
A five-point harmonic pattern (XABCD) using specific Fibonacci retracements that marks high-probability reversal zones.
Formula
AB = 61.8% of XA; BC = 38.2%–88.6% of AB; CD = 78.6% of XA
The Gartley Pattern is a harmonic structure defined by precise Fibonacci relationships between five points: X, A, B, C, and D. The pattern was introduced by H.M. Gartley in 1935 and popularized by Scott Carney.
All harmonic patterns define a Potential Reversal Zone (PRZ) at point D where multiple Fibonacci levels cluster. A bullish Gartley triggers a long near the PRZ; bearish triggers a short.
- AB = 61.8% retracement of XA
- BC = 38.2%–88.6% retracement of AB
- CD = 78.6% retracement of XA (the key ratio)
