AI London Session Range Indicator

AI London Session Range Indicator automatically draws the London session's opening range as a box on your chart, giving breakout and session traders an instant, objective reference for the high-volatility window that sets the tone for the rest of the trading day.

The indicator tracks the exact high and low reached during the configured opening-range window after the London session start, plots it as a shaded box, and keeps it visible for the rest of the session so you can watch for breakouts, retests, or range-bound setups relative to it.

Key features:

• Automatic detection of the London session start and opening-range window
• Configurable session start time and opening-range duration in minutes
• Clean, customizable box color for easy visual reference
• Works on any symbol and timeframe - Forex, metals, indices, crypto
• Rebuilds automatically each trading day with no manual redrawing
• Lightweight, chart-only visual tool with no repainting
• No DLLs, no external dependencies - installs in seconds

Input parameters:

• Session Start Time - the broker-time start of the London session, e.g. 07:00 (default 07:00)
• Opening Range Minutes - length of the opening range window in minutes (default 60)
• Box Color - color of the drawn range box (default Dodger Blue)

A must-have visual reference for London breakout strategies, session-open traders, and anyone who wants to see the day's key volatility window mapped out automatically instead of drawing it by hand every morning.
