Session Highlighter with Kill Zones [Exponential-X]

Session Highlighter with Kill Zones

Overview
This indicator provides comprehensive visualization of major forex trading sessions (Asian, London, and New York) with integrated kill zone detection and real-time session analytics. It helps traders identify optimal trading times by highlighting high-volatility periods and tracking session-specific price ranges.

What Makes This Original

While session indicators are common, this script uniquely combines several features that work together:

Kill Zone Integration: Highlights specific high-volatility windows within sessions (London: 02:00-05:00 EST, NY: 08:30-11:00 EST) when institutional activity typically peaks
Session Overlap Detection: Automatically detects and highlights when major sessions overlap (London-NY, Asian-London) with distinct visual cues
Real-Time Range Tracking: Calculates and displays percentage-based session ranges as they develop, not just historical data
Dynamic Statistics Dashboard: Live table showing current active session, session times, and comparative range percentages
Customizable Visual System: Flexible styling options including background shading, box overlays, and configurable line styles for session boundaries


How It Works

[u]Session Detection Logic[/u]
The script uses timezone-normalized session detection based on EST/EDT times. It converts the current bar's timestamp to New York time and determines which session(s) are active using minute-based calculations. This approach ensures accurate session detection regardless of your chart's timezone settings.

[u]Kill Zones[/u]
Kill zones represent periods within sessions when institutional traders are most active. The London kill zone (02:00-05:00 EST) captures pre-London open volatility, while the NY kill zone (08:30-11:00 EST) aligns with US economic data releases and market open activity.

[u]Range Calculations[/u]
Session highs, lows, and opens are tracked from the first bar of each session and updated in real-time. Range percentages are calculated as: [code]((High - Low) / Low) × 100[/code], providing a volatility measure that's comparable across different instruments and price levels.

[u]Visual System[/u]
Background shading: Color-coded zones for each session
Session boxes: Outline entire session ranges
H/L lines: Dynamic lines showing current session extremes
Open lines: Reference levels from session start
Overlap highlighting: Distinct colors when multiple sessions are active simultaneously


How to Use

Intraday Trading: Use kill zones to time entries during high-liquidity periods
Session Breakouts: Monitor for price breaks above/below session highs/lows
Range Trading: Trade between session boundaries during consolidation
Session Continuity: Observe how price behaves as sessions transition
Volatility Assessment: Compare current session ranges to typical values


Recommended Timeframes: Works on any timeframe, but most useful on 1m to 1H charts for intraday trading.
