OPEN-SOURCE SCRIPT
Session Range Boxes

This script automatically draws rectangular boxes on your chart to visualize specific time-based trading sessions. It calculates periods based on a configurable start time (in UTC) and a fixed duration (defaulting to 3-hour intervals). For each session, it tracks the High, Low, Open, and Close prices:
Historical Boxes: Once a session ends, it locks the High/Low range into a static box. It keeps a limited history (default 50 boxes) to prevent clutter.
Live Box: It draws a dynamic, updating box for the current active session that expands as the price moves. This can be toggled on/off instantly.
OHLC Lines: It optionally plots lines for the session's opening and closing prices within the live box.
Primary Use Cases
Session Analysis: Traders use this to visually isolate price action during specific market hours (e.g., London Open, New York Open, or custom Asian sessions) to identify volatility ranges and support/resistance levels formed during those times.
Range Boundaries: The boxes clearly define the high and low of a specific time window, helping traders spot breakouts or rejections at session extremes.
Custom Timeframes: Since it allows custom start times and durations (in seconds), it works for non-standard sessions (e.g., a specific 4-hour block or a custom "pre-market" window) that standard indicators might miss.
Visual Clarity: By separating sessions into distinct colored blocks, it helps remove noise from overlapping timeframes and focuses attention on the current session's behavior.
