Forex Market Hours
Market Structure & Participants
Forex market hours span 24 hours a day, five days a week, as trading rolls continuously across the major global sessions.
What are forex market hours?
Forex market hours describe the fact that currency trading runs continuously, 24 hours a day, five days a week, rather than opening and closing on a single fixed schedule the way a stock exchange does. This is possible because forex isn’t tied to one central exchange or location — it’s a decentralized global network of banks, brokers, and institutions, and as one major financial center closes for the day, another is just opening elsewhere in the world.
That continuous handoff between regional trading sessions — Sydney, Tokyo, London, and New York — is what keeps the market open around the clock on business days.
The weekly cycle
The forex week typically opens with the Sydney/Tokyo session early Monday morning (local Asia-Pacific time) and runs uninterrupted through the London and New York sessions, closing after the New York session wraps up on Friday evening (US time). Over the weekend, the market is effectively closed to new trading — no session is open anywhere — though prices can still react to weekend news, which is one reason weekend price gaps occur when trading resumes Sunday evening.
Why market hours affect trading conditions
Not every hour of the trading week offers the same conditions:
- Session overlaps (especially London-New York) bring the deepest liquidity and typically the tightest spreads.
- Late New York / early Sydney hours can be noticeably quieter, with thinner liquidity and choppier price action.
- Holidays in major financial centers can temporarily reduce liquidity even during normally active hours.
Why it matters for traders
Understanding forex market hours helps traders choose when to be active. A day trader looking for strong volume and tight spreads generally targets the London or New York sessions (or their overlap), while someone trading longer-term positions may care less about exact timing but still wants to be aware of weekend gap risk before holding a position into Friday’s close. Either way, market hours are one of the most basic, practical facts to internalize before placing a first trade.
