Session Range Boxes by AP

OVERVIEW
This indicator is designed for traders who require clear, visual boundaries for different trading sessions. It tracks the highest high and lowest low of up to six custom-defined time windows, wrapping them in dynamic boxes that update in real-time.

FEATURES

• 6 Customizable Sessions: Fully adjustable time ranges and names (Asia, London, NY Open, etc.).
  
• Real-Time Tracking: Session boxes expand dynamically as price creates new highs or lows during the session.
  
• Visual Organization: Individual color and transparency controls for each session to keep your chart clean.
  
• Auto-Delete Logic: Automatically removes older session boxes to prevent chart clutter (user-definable "Keep Last N Sessions").
  
• Timezone Flexibility: Built-in timezone support (IANA/Olson format) to ensure sessions align perfectly with your chart regardless of your local time.

HOW TO USE

1. Define your Timezone: Set the global "Session Timezone" to your reference market (e.g., America/New_York)
   
2. Input Sessions: Enter the 24-hour time ranges for your desired trading windows (e.g., 0930-1100).
   
3. Customize your settings & colors
   
4. Enjoy :)

SETTINGS

• Global: Toggle borders and labels globally, and set the auto-cleanup frequency.
  
• Session-Specific: Individual toggles for time, background fill, border color, and naming.

NOTES

• Of course I could add more functionality, but my main goal was to keep the indicator as small and simple as possible, while providing functionality which it was built for.
  
  
• Since the functionality is limited, I will keep this indicator open-source so everybody can edit and customize it to his own liking.
