Direct answer
Forex (foreign exchange) is not traded in one single worldwide market with the same opening and closing times everywhere. In practice, trading is most often unavailable or strongly reduced on weekends. Many brokers and trading platforms also treat certain public holidays as reduced-liquidity periods, where access may be limited or spreads/quotes may widen.
How forex “closed days” are determined
A useful way to interpret “closed” is to distinguish between (1) whether the market as a network of participants is active and (2) whether your specific trading venue (for example, a broker’s platform) accepts new trades.
Forex is traded globally across time zones, so coverage tends to run through most of the week. When people say “forex is closed on weekends,” they usually mean that major liquidity and dealer activity is much lower, and many platforms stop accepting new orders (or only allow limited operations) during part of the weekend period.
On holidays, activity may also be reduced because banks and liquidity providers are offline or operating on special schedules. This can mean that trading is still technically possible but with less stable pricing, or it can mean that some platforms stop accepting new trades for a time.
Example checks and how to verify
Because “closed” depends on the provider’s trading system, independent verification matters. Two common checks are:
- Check the market status or trading-hours display inside your broker’s platform for the instrument/currency pair you trade.
- Review the platform’s calendar for weekend and holiday hours (often listed as trading hours, market hours, or maintenance windows).
If your platform shows that new orders are not accepted, that is the most practical definition of “closed” for your use case. If it still allows quotes but with different behavior (wider spreads or slower execution), that is a different state than full closure.
Limitations and uncertainty
There is no single universal set of “closed days” for forex. Weekend closure timing can vary by broker and platform, and holiday schedules differ across countries and liquidity providers. Even when trading is not available, quotes may continue to update in some systems, so “no orders accepted” is a clearer operational test than “market feels quiet.”
