3-1-3 Pattern

This Pine Script indicator analyzes and visualizes a specific candlestick pattern called the "3-1-3 Pattern" across multiple timeframes. Here's what it does:
Core Functionality
Pattern Detection: The script looks for a 7-bar candlestick pattern:

Bearish 3-1-3: 3 red candles + 1 green candle + 3 red candles
Bullish 3-1-3: 3 green candles + 1 red candle + 3 green candles

Visual Output
When a 3-1-3 pattern is detected, the script:

Creates a colored box around the middle bar (bar 3) of the pattern
Adds a small label showing the pattern type ("Bear 1H" or "Bull 4H", etc.)
Extends the box forward until the price breaks above the pattern's high or below its low

Pattern Management
The script actively manages the patterns by:

Tracking active patterns for each timeframe separately
Removing expired patterns when price breaks the pattern's high/low levels
Extending boxes to the current time to keep them visible

Practical Use
This indicator helps traders:

Spot reversal patterns across multiple timeframes simultaneously
See confluence when patterns align on different timeframes
Track pattern validity (boxes disappear when invalidated by price action)

Essentially, it's a multi-timeframe pattern recognition tool that automatically identifies and tracks these specific 7-bar reversal patterns on your chart.
