Price Zones/Supply & Demand

Price Zones – Supply & Demand is an advanced indicator that automatically identifies key Supply, Demand, and Equilibrium zones based on volume distribution across price levels within a fixed lookback window.

The main purpose of this indicator is to provide structural price context, helping traders detect areas where an imbalance between buyers and sellers has historically occurred, and where price is more likely to react.

🔍 How it works

Fixed lookback analysis
The indicator analyzes a predefined number of historical bars to avoid repainting and ensure consistent and reliable behavior.

Volume distribution by price levels
The total price range within the lookback is divided into multiple segments (“Resolution”), measuring how much volume has been traded at each level.

Key zone detection

Supply Zone: Upper price area where a significant percentage of selling volume is concentrated.

Demand Zone: Lower price area with high concentration of buying volume.

Equilibrium: The midpoint of the analyzed range, representing balance between supply and demand.
