Trading Session High/Low Boxes

This indicator visualises key price levels by drawing boxes on the chart for:
Previous Trading Day – based on a customisable session (e.g., Asia open to New York close).
Previous 4‑Hour Block – the last completed 4‑hour period, using continuous global blocks (no gaps across days).
Current 4‑Hour Block – the ongoing 4‑hour period, updated live.
Each box spans the exact duration of the period and shows the highest high and lowest low reached during that time. Optional labels display the period name, high/low prices, and pip range.
