London First Hour High–Low (Last N Days)

This indicator marks the High and Low of the first hour of the London trading session (08:00–09:00 Europe/London time).
It is designed to help traders identify the key price range during the most active early London market period and use it for breakout or range-based strategies.

Features:
• Multi-day History – Plots the first-hour range for the past N sessions (default 15).
• Two Display Modes – Show only the top (High) line or display the full High–Low box.
• Extend-Right Control – Option to extend the marking for all sessions or only the latest session.
• Price Labels – Automatic price labels for the High and Low levels of each session.
• Customizable Styling – Adjustable colors, transparency, and line width.

How It Works:
1. The script uses the Europe/London timezone to detect the session start and end time.
2. It tracks the highest and lowest prices during the defined first hour.
3. At the session close, it plots a line or box to mark the range and optionally extends it to the right.
4. You can configure the number of past sessions to display.

Usage Example:
• Mark the London open range and look for breakouts above the High or breakdowns below the Low.
• Combine with volume, momentum, or volatility indicators for confirmation.

Inputs Overview:
• London Start / End – Define session time (HH:MM).
• Show only TOP line – Toggle between High line only or full High–Low box.
• Extend-right only latest session – Extend markings for the most recent session only.
• Keep last N sessions – Number of historical sessions to display.
