The trading clock
Sydney, Tokyo, London, New York: when each session runs, and why the overlaps matter most.
§1A market that follows the sun
The week opens in Sydney on Sunday evening (UTC), passes to Tokyo, then London, then New York, and closes on Friday evening.
Each session has a character. Asia is often calmer, London is the busiest single centre, and New York brings the big US data releases.
§2Overlaps
When two centres are open together — especially London and New York, roughly 12:00–16:00 UTC — liquidity peaks, spreads tighten and the largest moves tend to happen.
The session dial on our home page shows which centres are open right now, in your time.
remember this:
- Forex runs Sunday 21:00 to Friday 21:00 UTC.
- London is the largest session; the London–New York overlap is the busiest window.
- Match your trading hours to the pairs you trade.
