Auto Chart Patterns- Market Adapted

Auto Chart Patterns [Market Adapted] - Code Description
This Pine Script v5 indicator is a sophisticated automated chart pattern detection system that identifies geometric price patterns using zigzag analysis. Here's a comprehensive breakdown:

🎯 Purpose
Automatically detects and visualizes classic chart patterns (channels, wedges, triangles) on any timeframe by analyzing price pivot points.

🏗️ Core Architecture
Scanner Type (Custom Object)
JavaScript

type Scanner
bool enabled
string ticker
string timeframe
ScanProperties sProperties // Scanning configuration
DrawingProperties dProperties // Visual settings
array<Pattern> patterns // Detected patterns storage
array<Zigzag> zigzags // Zigzag pivots storage
Key Methods
getZigzagAndPattern()
Calculates zigzag pivots from price data
When new pivot detected → scans for patterns
Requires minimum 6 pivots in buffer
Uses multi-level zigzag analysis
Validates patterns against allowed configurations
scan()
Creates OHLC array from sources
Iterates through enabled zigzags (1-4)
Calls pattern detection for each zigzag configuration
🔄 Execution Flow
text

1. Initialize Scanner with all properties
2. On each bar (confirmed or real-time based on 'repaint'):
│
├─→ Build OHLC array
│
├─→ For each enabled Zigzag:
│ ├─→ Calculate pivots
│ ├─→ If new pivot detected:
│ │ ├─→ Scan for valid patterns
│ │ ├─→ Draw pattern if found
│ │ ├─→ Store in patterns array
│ │ ├─→ Trim old patterns (if > maxPatterns)
│ │ └─→ Trigger alert
│ └─→ Move to next zigzag level
│
└─→ Repeat on next bar
🎨 Display Features
Theme: Light/Dark mode
Pattern lines: Customizable width
Labels: Pattern name + pivot labels (with size options)
Zigzag: Optional display with custom color
Pattern limit: Auto-deletes oldest when exceeding max (default: 20)
⚡ Alerts
Triggers 'New Pattern Alert' when any valid pattern is detected.

💡 "Market Adapted" Features
Dual zigzag enabled by default (ZZ1 + ZZ2) for multi-timeframe sensitivity
Higher error threshold (30%) for volatile markets
Flexible pivot direction filtering per pattern type
Overlap avoidance to reduce noise
