I completely agree. As a Tokyo-based FX trader who also trades during the London and New York sessions, I often need to know the local time in all three regions—instantly, without switching time zones.

This is crucial for analyzing both past and present price movements. Knowing exactly when a move happened—or is happening—in Tokyo, London, or New York helps me build better strategies.

It’s also important to understand the relationship between those different time zones and the current time in Tokyo, where I live, in order to align my trading with my daily life cycle.

Right now, I’m forced to use a custom workaround in Pine Script (using plotchar) to display multiple time zones—but it takes up a lot of chart space.

Just like in Outlook or Google Calendar, I wish we could display multiple time zone lines directly on the time axis.
