Session Range Boxes GR v2.1

This indicator draws intraday range boxes for the main Forex sessions based on Europe/Budapest time (CET/CEST).

Tracked sessions (Budapest time):

Asia: 01:00 – 08:00

Frankfurt (pre-London): 08:00 – 09:00

London: 09:00 – 18:00

New York: 14:30 – 23:00

For each session, the script:

Detects the session start and session end using the current chart timeframe and the Europe/Budapest time zone.

Tracks the high and low of price during the session.

Draws a colored box from session open to session close, covering the full price range between the session high and low.

Draws a white midline inside every box at the midpoint between the session high and low (and keeps it visible for all past sessions).

Optionally plots a small label (“Asia”, “Fra”, “London”, “NY”) above the first bar of each session.

Color scheme:

Asia: soft orange box

Frankfurt: light aqua box

London: darker blue box

New York: light lime box

Use this tool to:
