Machine Learning-Inspired Supply & Demand Zones
Sep 2, 2025

The Machine Learning-Inspired Supply & Demand Zones indicator provides an automated framework for identifying high-probability institutional order flow areas by filtering market noise through algorithmic qualification tests. This tool helps traders isolate significant supply and demand zones based on price imbalance, volume participation, and structural validity.
Usage
The Usage section describes how the script can be used to identify potential market reversal or continuation points. Users can monitor two primary visual components:
- Supply Zones (Red Boxes): These represent areas of significant selling interest. Traders can look for shorting opportunities or profit-taking signals as price enters these zones.
- Demand Zones (Green Boxes): These represent areas of significant buying interest. Traders can look for long entries or pullbacks into these zones to find support.
The indicator dynamically manages zones based on market interaction. "Fresh" zones are displayed in vibrant colors, indicating they have not yet been re-tested and carry higher probability. Once a price interacts with a zone, it may be marked as "Tested" (dotted borders) or "Broken" (grayed out) depending on user settings. This allows for the identification of S/R flips, where a failed demand zone may act as future supply.
Details
The script qualifies zones using three core criteria inspired by institutional trading logic:
- Price Imbalance: The algorithm calculates the body size of the departure candle relative to the Average True Range (ATR). Only moves that are statistically significant relative to current volatility are considered.
- Volume Confirmation: It checks if the departure candle's volume exceeds a specific moving average of recent volume. This ensures the move is backed by "smart money" participation.
- Pivot Structure: Zones are only anchored to valid swing highs or lows, ensuring they originate from meaningful structural shifts rather than random price action.
The indicator utilizes arrays and user-defined types (UDTs) to manage up to a specific number of active zones simultaneously, ensuring chart performance remains optimized while providing historical context for broken zones.
Settings
Main Zone Settings
- Pivot Lookback Left: Number of bars to the left required to confirm a swing point.
- Pivot Lookback Right: Number of bars to the right required to confirm a swing point.
- Maximum Active Zones: Limits the number of supply and demand zones displayed on the chart to maintain clarity.
- Breakout Behavior: Determines if a zone is removed ("Delete Zone") or remains as a gray box ("Show as Broken (Flip)") once price closes through it.
Sensitivity Settings
- Zone Finding Logic: "Selective" requires both high volume and high imbalance; "Moderate" requires only one of the two.
- ATR Length: The period used to calculate volatility for imbalance detection.
- Imbalance Candle ATR Multiplier: Sets the threshold for how aggressive a price departure must be to qualify a zone.
- Volume Lookback Period: The window used to calculate average volume.
- Volume Multiplier: Sets the threshold for how much volume must exceed the average to qualify a zone.
Visual Settings
- Demand Zone Color: Customizes the color for bullish interest areas.
- Supply Zone Color: Customizes the color for bearish interest areas.
FAQ
How do I use the "Flip" feature for trading? When a zone is broken and the "Show as Broken (Flip)" setting is active, the zone turns gray. This indicates a potential change in market role, where an old demand zone may now act as resistance, providing a structure for "break and retest" strategies.
What is the difference between a Selective and Moderate logic? Selective logic is more restrictive, only drawing zones that exhibit both high volume and high price velocity. Moderate logic is more inclusive, allowing for zones that may have high volume but standard price movement, or vice versa.
