Decoding Harmonic Price Patterns
Harmonic trading is based on geometry and fractals. At its core, this approach incorporates the primary ratio and its derivatives (1.618, 0.618, etc.). Harmonic price patterns serve as indicators of potential trend retracements. These patterns reflect repeating cycles of investor psychology and often appear near significant support or resistance areas. They can also be combined with other technical analysis tools to confirm trade ideas.
👉 The best book for understanding harmonic patterns is “Harmonic Trading” by Scott M Carney.
🎲 Introduction to Harmonic Patterns
Harmonic patterns are geometry-based price formations identified on financial charts that suggest high-probability winning trades. They rely on precise Fibonacci ratios connecting distinct price swings, called legs. The key concept is that specific Fibonacci levels—such as 0.618, 1.618, and 0.786—help pinpoint potential reversal zones (PRZs), where the price is statistically more likely to change direction. Harmonic patterns generate signals of upcoming sharp reversals in currency rates, stocks, indices, and other instruments. These reversals typically occur within a price zone defined by two Fibonacci ratios:
-
The patterns tend to be more reliable on the M30 and higher timeframes.
-
Harmonic trading is considered a high-probability approach.
-
The overall win/loss ratio of harmonic trading strategies exceeds 70%.
🔄 Potential Reversal Zones (PRZs)
A Potential Reversal Zone (PRZ) is a price area on a chart where a market trend is statistically likely to reverse. PRZs are used by traders to pinpoint high-probability entry or exit points and to manage risk more effectively.

In my latest eBook, I introduced the ΔMP and Σ(ΔMP) technical analysis indicators. The purpose of ΔMP is to measure and visualize the historical momentum of any Forex pair or other financial-traded asset. The book can be found here.
