What Is Harmonic Trading?
Harmonic Trading combines Fibonacci ratios with geometric price patterns to spot precise trading opportunities. These methods rely on strict rules to identify potential reversal zones before price reaches critical turning points. No other technique offers this level of predictive structure for future price behavior.
Popular harmonic patterns like the Gartley, Bat, Butterfly, and Crab form the foundation of this approach. These tools provide traders with an objective framework for identifying reversal zones known as Potential Reversal Zones (PRZs)—areas where trend changes are highly likely.

-
Designed to work in real-time—perfect for intraday or swing traders.
Harmonic vs. Wolfe Wave – What’s the Difference?
While Harmonic patterns and Wolfe Waves both contain five legs and aim to forecast reversals, the rules for each are distinct:
-
Harmonic patterns use letters (X-A-B-C-D) and are heavily based on Fibonacci retracement ratios
-
Wolfe Waves use numbers (1–5) and follow a different geometric structure
-
For example, the Gartley requires point B to be a 61.8% retracement, while the Wolfe requires point 3 to dip below point 1, exceeding 100%
So while similar in visual form, each pattern type follows a unique set of rules.
