Huli (Reversal) Patterns

This indicator identifies and highlights specific candlestick patterns that commonly appear at potential reversal points in price action. The indicator scans for five distinct pattern types and visually marks them on your chart with customizable colors and optional signal shapes.
Pattern Detection:

Doji - Identifies candles with minimal body size relative to their range
Outside Bars - Detects engulfing patterns where the current bar completely contains the previous bar's range
Pin Bars - Recognizes candles with long wicks and small bodies at potential swing points
212 Pattern - Marks three-bar reversal formations with specific high/low relationships
222 Pattern - Identifies more complex three-bar reversal structures

Key Features:

Individual Pattern Controls - Enable/disable each pattern type independently
Volume Filtering - Optional volume increase requirement for each pattern (can be toggled on/off per pattern type)
Lookback Period - Adjustable lookback bars for each pattern to confirm swing highs/lows (default: 30 bars)
Visual Customization - Choose how patterns are highlighted:
Body only coloring
Body + wick coloring
Body + border coloring
Full candle coloring (body, wick, and border)
Signal Shapes - Optional arrows, triangles, diamonds, or dots to mark pattern occurrences
Custom Candle Colors - Apply custom colors to non-pattern candles for better visual organization
Pattern Priority System - When multiple patterns occur simultaneously, the indicator displays only the highest priority pattern (222 > 212 > Pin > Outside > Doji)

Configuration:

Each pattern type includes its own settings group where you can adjust colors, enable/disable volume requirements, and set lookback periods. The indicator allows for precise tuning to match your analysis preferences without cluttering the chart.

All patterns are evaluated using price structure and optionally volume, providing visual cues where multiple technical factors align. The indicator serves as a pattern recognition tool to assist in identifying areas of interest for further analysis.
