Order Flow System
Dec 6, 2025

The Fabio-Style Order Flow System indicator provides a comprehensive suite of order flow and market structure tools designed to visualize institutional activity and price inefficiencies.
Usage
The Usage section highlights the core components of the system and how they assist in identifying market opportunities:
- Order Flow & Delta: The tool calculates market imbalance using a smoothed delta. Background coloring shifts to reflect bullish or bearish dominance, while delta spikes indicate potential aggressive participation.
- Big Trade Detection: Identifies "Big Buy" and "Big Sell" prints when volume significantly exceeds the average. This helps in spotting institutional aggression at key levels.
- Low Volume Nodes (LVN): Automatically flags zones with minimal trading activity. Retests of these nodes are often high-probability reaction points.
- Volume Profile: Displays a lightweight, bucket-based intrabar profile. It highlights volume distribution over a user-defined lookback period to identify high and low-interest areas.
- Fair Value Gaps (FVG) & Order Blocks (OB): Detects three-bar imbalances (FVGs) and displacement-based Order Blocks. These are plotted as visual zones to identify potential support and resistance.
- Liquidity Grabs: Highlights wick-based sweeps of liquidity, useful for identifying "stop runs" or potential trend reversals.
- Strategy Dashboard: Provides a real-time summary of delta strength, active big trades, and the most recent directional impulse.
Details
This tool is constructed to unify several "Smart Money" concepts into a single interface. It utilizes ATR-based filtering for Order Block and impulse detection to ensure zones are based on significant market volatility rather than noise. The Volume Profile implementation is specifically optimized for performance, using bucket-based calculations to minimize the computational load on the platform while maintaining accuracy.
