The forex market opens at different times depending on which trading session you're in

The forex market runs 24 hours a day across different time zones, but from a Canadian perspective, the market opens and closes at specific times in your local time. The North American session — which includes Canada — opens at 8:00 a.m. Eastern Time and closes at 5:00 p.m. Eastern Time. This is when the New York market is active and when most Canadian traders do their trading.

If you're in a province west of Ontario, you'll need to adjust for your local time zone. In Mountain Time, the market opens at 6:00 a.m. and closes at 3:00 p.m. In Pacific Time, it opens at 5:00 a.m. and closes at 2:00 p.m. These times stay the same year-round because the forex market does not observe daylight saving time in the same way stock markets do — the shift happens on different dates.

The forex market actually never closes completely. Before the North American session starts, the Asian session is already trading (roughly 5:00 p.m. to 2:00 a.m. Eastern Time the next day), and the European session runs from 2:00 a.m. to 11:00 a.m. Eastern Time. Many Canadian traders watch these sessions too, but the North American session is when spreads are tightest and volume is highest for most currency pairs.

Key Takeaways

  • The North American forex session opens at 8:00 a.m. Eastern Time and closes at 5:00 p.m. Eastern Time, which is when most Canadian traders are active.
  • Adjust these times for your province: 6:00 a.m. to 3:00 p.m. Mountain Time, or 5:00 a.m. to 2:00 p.m. Pacific Time.
  • The forex market trades 24 hours across Asian, European, and North American sessions, but liquidity and spreads vary by session.
  • Daylight saving time transitions happen on different dates for forex markets and stock markets, so check your broker's schedule during spring and fall.

Why opening time matters for Canadian traders

The time the market opens affects how much it costs you to trade. When the North American session opens at 8:00 a.m. Eastern, the European session is still active for a few hours. This overlap — called the London-New York overlap — is when spreads (the difference between buy and sell prices) are narrowest and volume is highest. If you trade during this window, you pay less per trade.

Outside the North American session, spreads widen and volume drops. If you trade the EUR/USD pair at 3:00 a.m. Eastern Time, you'll pay more per pip than if you trade it at 9:00 a.m. This matters whether you're a day trader making multiple trades or a swing trader holding positions overnight.

How daylight saving time affects forex market hours

Daylight saving time creates confusion because the forex market and North American stock markets shift on different dates. In 2024, for example, stock markets in the U.S. and Canada shifted on March 10 and November 3, but the forex market's effective opening times may shift on different dates depending on your broker's location and how they handle the transition.

The safest approach is to check your broker's trading hours directly during the weeks when clocks change. Most brokers publish updated hours on their website or in your trading platform. Don't assume the times stay the same — a broker based in the U.S. may shift hours on a different date than a Canadian broker.

Trading outside the North American session

Some Canadian traders watch the Asian session (5:00 p.m. to 2:00 a.m. Eastern) because it includes the Tokyo and Sydney markets, where the Japanese yen and Australian dollar are most active. The European session (2:00 a.m. to 11:00 a.m. Eastern) includes the London market, where the British pound and euro move most.

If you trade these pairs during their home sessions, you get tighter spreads and faster execution. However, this means trading outside normal business hours in Canada — early morning or late evening. Your broker must support round-the-clock trading, and you need to manage the fatigue that comes with off-hours trading.

What your broker's hours actually mean

Your broker's trading hours are not the same as the forex market's hours. A broker can close its platform to new trades even though the market is still open elsewhere. Some brokers close for a few hours overnight (usually between 5:00 p.m. and 6:00 p.m. Eastern) for system maintenance, even though forex trading continues in Asia.

Check your broker's specific hours in your account settings or their help section. If you want to trade 24 hours, confirm that your broker actually supports it. Some brokers advertise 24-hour trading but close certain currency pairs or restrict trading during low-volume hours.

Planning your trading schedule around market hours

If you work a regular job and can only trade before or after work, the North American session opening at 8:00 a.m. Eastern may not fit your schedule. You have three options: trade the hour or two before work (during the European session), trade after work (during the North American session close or early Asian session), or trade on weekends if your broker allows it.

Each option has trade-offs. Early morning trading means lower spreads but less time before work. After-work trading fits your schedule but may catch the market when it's slowing down. Weekend trading is possible with some brokers, but volume is much lower and spreads are wider.

Frequently Asked Questions

Can I trade forex before 8:00 a.m. Eastern Time?

Yes. The European and Asian sessions are already trading, and most brokers allow you to trade during these hours. However, spreads will be wider and volume lower than during the North American session. Check your broker's hours to confirm they support pre-market trading.

Does the forex market close on weekends?

Yes. The market closes after 5:00 p.m. Eastern on Friday and reopens at 5:00 p.m. Eastern on Sunday (when the Asian session starts in Sydney). Some brokers allow weekend trading on certain pairs, but it's not standard and spreads are very wide.

What time should I trade if I want the tightest spreads?

Trade during the London-New York overlap, which runs from roughly 8:00 a.m. to 11:00 a.m. Eastern Time. This is when both European and North American markets are active, volume is highest, and spreads are narrowest for most major pairs.

Do I need to adjust my trading times when daylight saving time changes?

Check your broker's website during the week daylight saving time shifts. Some brokers adjust automatically; others require you to note the change manually. Don't assume your trading times stay the same — confirm with your broker before the shift happens.

Why is the forex market open 24 hours if I can only trade during certain times?

The forex market is decentralized and runs across multiple exchanges in different time zones, so it never fully closes. However, your broker may not offer trading during all hours, and spreads vary widely depending on which session is active. You can trade 24 hours, but the cost and execution quality change throughout the day.
