How the market is structured
Sessions, hours and the best times to trade
3 min
Forex runs 24 hours a day, five days a week, from the Monday open in Asia to the Friday close in New York. But activity is far from uniform across those hours.
The three major sessions
- Sydney/Tokyo (Asian session) — quieter, with JPY and AUD pairs most active.
- London (European session) — the largest by volume; spreads tighten and moves get cleaner.
- New York (US session) — high activity, especially around US data releases.
The overlaps are the action
The most active window of all is the London–New York overlap (roughly 13:00–16:00 UTC), when both financial centres are open at once. Liquidity peaks and the biggest moves often happen here.
Days of the week
- Monday often starts slow as the market finds direction.
- Tuesday to Thursday tend to carry the cleanest trends and the most scheduled news.
- Friday can reverse or thin out in the afternoon as traders close positions for the weekend.
A practical takeaway
Trade the sessions that match the pairs you follow, and be aware that holidays and the weekend gap (the market reopens Sunday evening UTC and can open at a different price than Friday’s close) change the picture. Always cross-check the economic calendar — covered in the Analysis track — before a session.
