OB

Advanced Order Block & Liquidity Mapping Tool

This open-source script is designed to help traders identify market structure and key liquidity areas using a combination of fractal-based order block detection and dynamic/static liquidity mapping.

Features Overview:

- Detects bullish and bearish order blocks using 3-bar and 5-bar fractal patterns
- Automatic removal of invalidated order blocks when price bodies fully break above/below OB highs/lows
- Fair Value Gap (FVG) validation option to increase signal quality
- Time-based label system for session or bar analysis
- Highly customizable visuals: line styles, label positions, widths, colors, and time offsets

🛠️ Custom Enhancements:
This version introduces a key improvement: order blocks are automatically removed once they are considered invalid, specifically when the body of a future candle breaks through the high or low of the original OB — not just the wick. This enhances the clarity and reliability of the displayed levels by dynamically filtering out broken zones.

🧠 Based on Open Source Work:
This script includes adapted logic from the open-source Orderblocks script by Nephew_Sam_.
The original detection mechanism has been extended with new invalidation logic and improved visual rendering.

Recommended Usage:
Best suited for intraday or swing-trading strategies based on market structure and smart money concepts (SMC). Works well on 5m to 4h timeframes. Inputs are adjustable to suit varying volatility and session preferences.
