ICT Sessions Ranges [SwissAlgo]

ICT Session Ranges - ICT Liquidity Zones & Market Structure

OVERVIEW
This indicator identifies and visualizes key intraday trading sessions and liquidity zones based on Inner Circle Trader (ICT) methodology (AM, NY Lunch Raid, PM Session, London Raid). It tracks 'higher high' and 'lower low' price levels during specific time periods that may represent areas where market participants have placed orders (liquidity).

PURPOSE
The indicator helps traders observe:

• Session-based price ranges during different market hours
  
• Opening range gaps between market close and next day's open
  
• Potential areas where liquidity may be concentrated and trigger price action
  

SESSIONS TRACKED
1. London Session (02:00-05:00 ET): Tracks price range during early London trading hours
2. AM Session (09:30-12:00 ET): Tracks price range during the morning New York session
3. NY Lunch Session (12:00-13:30 ET): Tracks price range during typical low-volume lunch period
4. PM Session (13:30-16:00 ET): Tracks price range during the afternoon New York session

CALCULATIONS

• Session High/Low: The highest high and lowest low recorded during each active session period
  
• Opening Range Gap: Calculated as the difference between the previous day's 16:00 close and the current day's 09:30 open
  
• Gap Mitigation: A gap is considered mitigated when the price reaches 50% of the gap range
  
• All times are based on America/New_York timezone (ET)

• Subtle background boxes highlight each session range
  
• Labels identify each session type
  
• Orange shaded boxes indicate unmitigated opening range gaps
  
• Dotted line at 50% gap level shows mitigation threshold
  

FEATURES

• Toggle visibility for each session independently
  
• Customizable colors for each session type
  
• Automatic removal of mitigated gaps
  
• All drawing objects use transparent backgrounds for chart clarity
  

ICT CONCEPTS
This tool relates to concepts discussed by Inner Circle Trader regarding liquidity pools, session-based analysis, and gap theory. The indicator assumes that session highs and lows may represent areas where liquidity is concentrated, and that opening range gaps may attract price until mitigated.

USAGE NOTES

• Best used on intraday timeframes (1-15 minute charts)
  
• All sessions are calculated based on actual price movement during specified time periods
  
• Historical session data is preserved as new sessions develop
  
• Gap detection only triggers at 09:30 ET market open
  

DISCLAIMER
This indicator is for educational and informational purposes only. It displays historical price levels and time-based calculations. Past performance of price levels is not indicative of future results. The identification of "liquidity zones" is a theoretical concept and does not guarantee that orders exist at these levels or that prices will react to them. Trading involves substantial risk of loss. Users should conduct their own analysis and risk assessment before making any trading decisions.
