Harmonic Trading, Volume One: Profiting from the Natural Order of the Financial Markets
by Scott M. Carney
Overview
Published in 2010 by FT Press, this is the first of two volumes by Scott Carney, founder of HarmonicTrader.com and originator of the Harmonic Trading methodology. The book systematizes a price pattern recognition approach based on specific Fibonacci ratio measurements, defining precise rules for identifying and trading harmonic patterns.
Fibonacci Foundation
Chapter 2 establishes the mathematical basis: Fibonacci numbers, the golden ratio (1.618), and derived ratios (0.382, 0.500, 0.618, 0.786, 0.886, 1.272, 1.618). These ratios define the proportional relationships within each harmonic pattern.
The Harmonic Patterns
- AB=CD Pattern: The foundational structure where two equivalent price legs create a symmetrical pattern with specific Fibonacci relationships.
- Bat Pattern: Defined by a 0.886 XA retracement at point D, with specific BC projection requirements.
- Gartley Pattern: The "ideal" version requires a 0.618 XA retracement at point B and completion at the 0.786 XA retracement.
- Crab Pattern: Features an extreme 1.618 XA extension at point D, making it the most extended harmonic pattern.
- Butterfly Pattern: Completes beyond the initial XA leg with specific ratio requirements at each turning point.
Potential Reversal Zone (PRZ)
Carney's key innovation is the PRZ concept: a price zone where multiple Fibonacci levels from different aspects of the pattern converge, creating a high-probability reversal area. Trade execution focuses on price action within the PRZ.
Trade Management
The Harmonic Trade Management System covers: initial stop loss placement relative to the PRZ, profit targets at specific Fibonacci levels of the completed pattern, trailing stop techniques, and pattern violation rules that signal when a trade thesis has failed.
