Technical Analysis

Harmonic Patterns

Definition

Chart patterns based on Fibonacci ratios (Gartley, Butterfly, Bat, Crab) that identify potential reversal zones with high precision.

Why Harmonic Patterns Matters to Traders

Technical analysis traders rely on Harmonic Patterns to read price action objectively. Knowing exactly what it signals — and what it does not — separates disciplined chart readers from gut-feel traders.

Example

A Gartley pattern completing at the 78.6% Fibonacci retracement level signals a potential reversal.
