Quantura - Session High/Low

Introduction
“Quantura – Session High/Low” is a professional-grade session mapping indicator that automatically identifies and visualizes the highs, lows, and ranges of key global trading sessions — London, New York, and Asia. It helps traders understand when and where liquidity tends to accumulate, allowing for better market structure analysis and session-based strategy alignment.

Originality & Value
This indicator unifies the three most influential global sessions into a single, adaptive visualization tool. Unlike typical session indicators, it dynamically updates live session highs and lows in real time while marking session boundaries and transitions. Its multi-session management system allows for immediate recognition of overlapping liquidity zones — a crucial feature for institutional and intraday traders.

The value and originality come from:

• Real-time tracking of session highs, lows, and developing ranges.
  
• Simultaneous visualization of multiple global sessions.
  
• Optional vertical range lines for clearer visual segmentation.
  
• Customizable session times, colors, and time zone offset for global accuracy.
  
• Automatically extending and updating lines as each session progresses.
  

Functionality & Core Logic

• Detects the start and end of each trading session (London, New York, Asia) using built-in time logic and user-defined UTC offsets.
  
• Initializes session-specific high and low variables at the start of each new session.
  
• Continuously updates session high/low levels as new candles form.
  
• Draws color-coded horizontal lines for each session’s high and low.
  
• Optionally adds vertical dotted lines to visually connect session range extremes.
  
• Locks each session’s range once it ends, preserving historical structure for review.
  

Parameters & Customization

• New York Session: Enable/disable, customize time (default 15:30–21:30), and set color.
  
• London Session: Enable/disable, customize time (default 09:00–16:30), and set color.
  
• Asia Session: Enable/disable, customize time (default 02:30–08:00), and set color.
  
• Vertical Line: Toggle dotted vertical lines connecting session high and low levels.
  
• UTC Offset: Adjust session timing to align with your chart’s local time zone.
  

Visualization & Display

• Each session is color-coded for quick identification (default: blue for London, red for New York, green for Asia).
  
• Horizontal lines track evolving session highs and lows in real time.
  
• Once a session closes, the lines remain fixed to mark historical range boundaries.
  
• Vertical dotted lines (optional) visually connect the session’s high and low for clarity.
  
• Supports full overlay display without interfering with other technical indicators.
  

Use Cases

1. Identify liquidity zones and range extremes formed during active trading sessions.
   
2. Observe session overlaps (London–New York) to anticipate volatility spikes.
   
3. Combine with volume or market structure tools for session-based confluence.
   
4. Track how price interacts with prior session highs/lows to detect potential reversals.
   
5. Analyze session-specific performance patterns for algorithmic or discretionary systems.
   

Limitations & Recommendations

• The indicator is designed for intraday analysis and may not provide meaningful output on daily or higher timeframes.
  
• Adjust session times and UTC offset based on your broker’s or exchange’s timezone.
  
• Does not provide trading signals — it visualizes session structure only.
  
• Combine with liquidity and volatility indicators for full contextual understanding.
  

Markets & Timeframes
Compatible with all asset classes — including crypto, forex, indices, and commodities — and optimized for intraday timeframes (1m–4h). Particularly useful for traders analyzing session overlaps and volatility transitions.
