AI Harmonic Pattern Scanner

Automatic detection of the classic harmonic patterns, with PRZ, stop and targets drawn for you.

How it works

A built-in swing algorithm finds turning points using a depth setting and a minimum swing size measured in ATR. Each time a new swing is confirmed, the scanner checks the five swings before it as X-A-B-C-D. It looks for Gartley, Bat, Butterfly, Crab and Cypher, plus AB=CD on the last four points. Each pattern uses standard Fibonacci ratio ranges with an adjustable tolerance.

A pattern is reported only when point D is final, which means price has already reversed from D by the minimum swing size. The pattern is drawn with filled triangles and labeled legs, together with its name and direction. You also get a potential reversal zone (PRZ) rectangle, a suggested Stop Loss beyond X or beyond the PRZ, and targets at 38.2% and 61.8% of the AD leg.

Key features

• Internal swing detection, no external ZigZag file
• Gartley, Bat, Butterfly, Crab, Cypher and AB=CD, each one can be turned on or off
• Adjustable ratio tolerance (10% by default)
• PRZ rectangle, Stop Loss and TP1/TP2 levels with prices
• Bullish and bearish colors, last N patterns kept on the chart
• Buffers for EA use: 0 bullish pattern, 1 bearish pattern (on the confirmation bar)
• Popup, push and sound alerts on new completed patterns

Recommended

Any symbol, M15 to D1. Use a higher depth on lower timeframes to filter out noise.

Inputs

Swing depth, deviation in ATR, ATR period, ratio tolerance, pattern switches, Stop Loss mode and buffer, PRZ length, number of patterns to keep, colors, triangle fill, max bars to calculate and alert options.

Note

Only completed patterns are shown. Once a pattern is confirmed on a closed bar, it does not repaint.
