Trading session clock

Which sessions are open now, in your timezone, including overlaps.

Works without an account Formula printed with the answer Assumptions listed No live price hardcoded

Date and time

Read as UTC. Session windows are fixed UTC hours, so the answer is the same wherever you are.

Nothing is stored or emailed. The maths runs on the figures you typed.

What this tells you

Liquidity and volatility are shaped by which centres are awake. The overlaps matter most.

Method

Session windows are defined in UTC and converted to your chosen timezone at render, so daylight saving is handled by the timezone database rather than a hardcoded offset. London/New York and Tokyo/London overlaps are called out explicitly.

Where the numbers come from

Contract sizes, pip conventions and session hours come from one published specification table, and the same class answers on the page and through the API. A conversion rate is only ever the figure you enter — the site does not fetch a price, because a hardcoded quote would be wrong for your broker and stale in seconds.

Do these hours match my broker?

They match the widely used server conventions printed on the page. Broker server clocks differ, so always check your platform before relying on a session boundary.
