Automated Harmonic Pattern Detection for Precision Reversal Trading
Identify high-probability reversal structures instantly with a fully automated harmonic pattern engine designed for NinjaTrader.
Built for traders who demand accuracy, structure, and automation-ready pattern recognition.

Key Features

• 8 Harmonic Patterns Detected: Bat, Alt Bat, Gartley, Crab, Deep Crab, Shark, Butterfly, Cypher.
• Automatic Pattern Recognition: Real-time detection based on precise Fibonacci relationships.
• Custom Pattern Configuration: Adjust retracement ranges or enforce exact ratios.
• Detection & Update Logic: Patterns dynamically update as price evolves.
• Pattern Labeling: XABCD structure displayed clearly on chart.
• Retracement Visualization: Shows actual Fibonacci percentages for validation.

Advanced Trading & Automation

• Automation-Ready Outputs: All pattern signals exposed for strategy building.
• Pattern Detection Signals: Bullish and bearish signals with update tracking.
• Pattern Type Identification: Numeric output for each detected pattern.
• Cancellation Signals: Automatically flags invalidated patterns.
• Swing Switch Detection: Confirms late reversals for additional strategy logic.
• Backtesting Compatible: Reliable structure for systematic evaluation.

How It Works

The indicator uses swing-based logic to construct XABCD patterns and validate them against configurable Fibonacci ratios. Detection occurs at Point D — the potential reversal zone — where trade opportunities are typically evaluated.

As highlighted in the manual, patterns are identified using zigzag swing structures and continuously updated as price evolves.

If price invalidates the structure, the pattern is either removed or marked as cancelled depending on your settings.

Trading Applications

• Reversal trading at completion of harmonic structures
• Confluence with support and resistance zones
• Fibonacci-based strategy development
• Pattern-based automated trading systems
• Swing structure confirmation and timing

What Makes This Different

• Fully automated detection and validation of complex patterns
• Real-time updates and redraw logic for accuracy
• Pattern cancellation tracking for risk management
• Detailed Fibonacci retracement visibility
• Designed specifically for automation workflows

Platform Compatibility

NinjaTrader 8
Compatible with Strategy Builder, BloodHound, and Blackbird

Important Notes

• Patterns may update or cancel as price evolves
• Always use additional confluence before entering trades
• Best used with support/resistance and market structure

Frequently Asked Questions

Do patterns repaint?
Patterns can update as price evolves, especially at Point D, but this reflects real-time market structure — not repainting.

Can I automate strategies using this?
Yes. All pattern detection, type, and cancellation signals are available for automation.

Why do patterns disappear?
Patterns are cancelled when price invalidates the structure based on Fibonacci rules.

Can I customize pattern rules?
Yes. You can define retracement ranges or enforce exact ratios for each pattern.
