OWL Supply & Demand Detector v1.01
Simple & Complete User Guide
What is it? The OWL Supply & Demand Detector is a MetaTrader 5 indicator that automatically finds Supply zones (selling areas) and Demand zones (buying areas) on the chart. It also shows how strong each zone is, whether it has been tested, and includes a clean dashboard with useful information.
Main Features
- Automatically draws Supply and Demand zones
- Gives each zone a strength score from 1 to 5 stars (★★★★★)
- Shows if a zone is Fresh, Tested, or Mitigated
- Counts how many times a zone has been retested
- Displays a professional dark dashboard with key statistics
- Optional alerts when price enters a fresh zone
- Clean and easy-to-read visuals
How It Works (Simple Explanation)
- The indicator looks for a base candle (the turning point candle).
- Then it checks if strong candles moved away from that base (called impulse candles).
- If it finds enough impulse candles, it draws a rectangular zone.
- The zone gets a strength score based on how strong the move was.
- As price moves, the indicator updates whether the zone is still fresh, has been tested, or has been broken (mitigated).
Supply Zone = Good area to sell Demand Zone = Good area to buy

Best Tips:
