Advanced Harmonic Pattern Detector v6

🔷 Advanced Harmonic Pattern Detector & Backtesting Suite (Pine Script v6)

The Advanced Harmonic Pattern Detector is a professional-grade technical analysis tool designed to automatically identify high-probability harmonic price patterns using industry-standard Fibonacci ratios. Built for traders who rely on precision, structure, and statistical validation, this indicator delivers real-time pattern detection, predictive reversal zones (PRZ), and integrated backtesting in a single, powerful package.

This tool is suitable for forex, crypto, indices, stocks, and futures, across all timeframes.

📐 Supported Harmonic Patterns

The indicator detects both bullish and bearish variations of the following harmonic formations:

✔ Gartley
✔ Bat
✔ Alternate Bat
✔ Butterfly
✔ Crab
✔ Deep Crab
✔ Shark
✔ AB=CD
✔ 3-Drive
✔ 5-0

Each pattern is validated using 2026 industry-standard Fibonacci ratio rules, ensuring accuracy and consistency with professional harmonic trading methodologies.

🧠 Smart Pattern Detection Engine

• Automatic swing-high and swing-low recognition
• Exact Fibonacci ratio validation for each pattern leg (XA, AB, BC, CD)
• Pattern-specific tolerance ranges to prevent over-filtering
• Correct handling of extension-based patterns (Butterfly, Crab, Shark)
• Non-repainting logic once patterns are confirmed

The detection engine is optimized to balance precision and frequency, helping traders avoid false signals while still capturing meaningful setups.

🎯 Predictive PRZ & Trade Planning

• Automatically plots Potential Reversal Zones (PRZ)
• Fibonacci confluence-based reversal areas
• Visual pattern labeling directly on the chart
• Clear bullish and bearish pattern differentiation

These features allow traders to anticipate reversals before price reacts, rather than chasing moves after they occur.

📊 Built-In Backtesting & Performance Metrics

The indicator includes a fully integrated strategy-style backtesting engine, allowing traders to evaluate historical performance without leaving the chart:

• Pattern-based trade simulation
• Configurable take-profit and stop-loss levels
• Risk-reward customization
• Win rate, total trades, and performance statistics
• Results displayed in an on-chart performance table

This enables traders to validate harmonic patterns statistically, not emotionally.

⚙️ Advanced Customization Options

• Enable or disable individual harmonic patterns
• Toggle bullish and bearish pattern detection independently
• Adjustable Fibonacci tolerance levels
• Custom take-profit and stop-loss ratios
• Works across all symbols and timeframes

Whether you are a discretionary trader or a systematic strategist, the indicator adapts to your trading style.

🚀 Who This Indicator Is For

• Harmonic pattern traders
• Price action traders
• Fibonacci-based strategists
• Forex, crypto, and index traders
• Traders seeking rule-based, backtested setups

This is not a repainting signal tool — it is a professional harmonic analysis and decision-support system.
