Market Sessions — Vertical

57
A clean visual guide to global market sessions.

This indicator plots vertical lines at the opening and closing times of the four major forex sessions:
London, New York, Tokyo, and Sydney.

Fully customizable — toggle each session on/off, choose separate colors for open/close, and enable/disable labels.
Supports both Local (auto-DST) and GMT (fixed) modes — switch between realistic market-clock times or the standardized UTC schedule used by most trading resources.
Helps you visually identify session overlaps (e.g., London–New York) where volatility typically increases.
Ideal for forex, indices, and commodities traders who trade around session opens.

Default session times (GMT mode):

Sydney 21:00 – 06:00 GMT

Tokyo 00:00 – 09:00 GMT

London 08:00 – 17:00 GMT

New York 13:00 – 22:00 GMT

Tip: Set Anchor times by → Local (auto-DST) if you want the lines to follow each region’s real-world daylight-saving adjustments automatically.

Clean, lightweight, and built for traders who want precise, minimal clutter — just the key time windows that move the market.
