Master Harmonic Patterns

Click here to explore monthly indicator kits for every trading style

Harmonic patterns are precise. They require five exact swing points, Fibonacci ratios that align within a tight tolerance, and a specific XABCD structure that forms over time. Spotting one manually means constant chart watching and ratio checking. Miss the D point and the setup is gone. Master Harmonic Patterns handles all of it automatically.

It scans the chart in real time, identifies swing pivots, measures every Fibonacci leg, and draws the full XABCD structure the moment a valid pattern takes shape. Ten pattern types are covered, including Gartley, Butterfly, Bat, Alt Bat, Crab, Deep Crab, Shark, Cypher, 5-0, and ABCD, each in both bullish and bearish form.

What separates it from basic harmonic tools is the scoring engine. Each detected pattern is scored based on how closely its legs match the ideal Fibonacci ratios. When two patterns compete for the same price region, the one with the tighter ratio fit wins. You see the strongest structure on that area of the chart, not just the first one found.

The Potential Reversal Zone at point D is where the trade begins. When price reaches the PRZ, the indicator marks it clearly. Enable the reversal signal and a confirmed entry fires when price closes back through the PRZ with an ATR buffer behind it. One signal per pattern, no repeats.

Key Features

• 10 harmonic pattern types detected automatically. Gartley, Butterfly, Bat, Alt Bat, Crab, Deep Crab, Shark, Cypher, 5-0, and ABCD, in both bullish and bearish form. Every major harmonic structure covered in one indicator.

• Fibonacci ratio validation on every leg. The indicator measures AB/XA, BC/AB, CD/BC, and AD/XA against precise ratio targets. Tolerance is adjustable from 2 to 20 percent. Tighter tolerance means fewer patterns and stricter matches.

• Score-based pattern priority. Each pattern receives a score based on how cleanly its ratios align. When patterns overlap, the strongest one stays. You never get a weaker setup bumping a better one off the chart.

• PRZ with confirmed reversal signals. The Potential Reversal Zone is drawn at point D, where price is expected to turn. Enable reversal signals and the indicator fires once price closes back through the PRZ by a meaningful ATR margin. One signal, never repeats.

• 3 detection presets plus custom. Fast for intraday setups, Balanced for all timeframes, Swing for daily and weekly structures. Or set your own Look Left and Look Right values manually.

• XABCD labels and Fibonacci ratios on chart. See exactly which swing point is X, A, B, C, and D. Enable ratio labels and the actual Fibonacci values appear on each leg so you can verify the setup at a glance.

• Alerts on pattern formation and PRZ reversal. Get notified the moment a harmonic completes or a reversal confirms. No chart watching required.

How To Use It

Add the indicator to any chart and select a detection preset. Fast works well for scalping and intraday charts. Balanced suits most timeframes. Swing is designed for daily and weekly setups where patterns develop over many bars.

When a harmonic pattern appears, the XABCD structure is drawn and the PRZ is marked at point D. That is the area where price is expected to react. Enable the reversal signal and wait for confirmation. When price closes back through the PRZ with enough force, the signal fires. That is your entry trigger, not the pattern completing, but price proving the reversal is real.

Set alerts for pattern formation and reversal confirmation, then step away from the chart. The indicator keeps watching.
