Session Dominance Profile [Pointalgo]

1 719
Session Dominance Profile is a visual volume-distribution tool that shows which global trading session (Asia, London, or New York) dominates price activity across different price levels within a defined historical range.

The indicator builds a horizontal volume profile using candle close prices and volume, then classifies each price level by the session that contributed the highest volume.

How It Works :
  • The script analyzes a configurable lookback period
  • Price range is divided into multiple horizontal bins
  • Volume is accumulated per price level
  • Each bin is split into three session buckets:

  • Asia Session (Yellow)
  • London Session (Blue)
  • New York Session (Red)

  • The session with the highest volume at that price level determines the color


This results in a Session-based Dominance Profile, helping traders visually identify:
  1. Where major sessions were most active
  2. Session-specific acceptance or rejection zones
  3. Potential intraday and swing reaction areas


Practical Use Cases :
Identify price levels dominated by a specific session
Understand session rotation and participation
Combine with:
  • Market structure
  • Support & resistance
  • VWAP or moving averages

Useful for intraday, scalping, and swing trading
Inputs Explained:
  • Lookback – Number of historical bars used to build the profile
  • Resolution – Number of price bins (higher = more detail)
  • Fixed Width (Bars) – Maximum horizontal width of the profile
  • Offset (Bars) – Distance of the profile from the current bar
  • Profile Direction – Left-to-Right or Right-to-Left rendering

Session Time Reference:
All sessions are calculated using UTC time.
Important Notes:
  • This indicator is visual and analytical only
  • It does not generate buy or sell signals
  • No repainting: the profile is calculated on the last bar only
  • Designed for educational and research purposes
