Forex Market Hours Explained: Sessions, Overlaps, and the Best Times to Trade

The forex market runs around the clock from Sunday evening to Friday night. No single exchange opens or closes it. Instead, banks, brokers, and institutional traders across the globe keep quoting prices continuously, passing the baton from one region to the next as business hours shift.

But “open 24 hours” does not mean “equally active 24 hours.” Some windows are packed with volume and tight spreads. Others are so quiet that even small trades can move prices unpredictably. Knowing the difference is one of the most practical edges a trader can have.

This article walks through every major session, what happens during the overlaps, and how to match your trading schedule to the conditions that actually suit your strategy.

How the Forex Market Actually Works Around the Clock

Unlike stock markets, forex has no central exchange. It runs as an over-the-counter (OTC) market, meaning trades happen directly between participants: banks, institutions, brokers, and retail traders, all connected through electronic networks.

The market opens at 22:00 UTC on Sunday (when Sydney comes online) and closes at 22:00 UTC on Friday (when New York wraps up). That is roughly 120 hours of continuous trading each week.

Within that window, four major financial centres take turns leading activity: Sydney, Tokyo, London, and New York. Each has its own peak hours, its own preferred currency pairs, and its own personality. Understanding this is fundamental to how forex trading works in practice.

The Four Major Forex Sessions

Sydney Session

Sydney kicks things off. It is the smallest of the four major sessions by volume, which means price moves tend to be modest compared to what happens later in the day. AUD and NZD pairs see the most activity here, along with some movement in Asian crosses.

Think of Sydney as the market warming up rather than running at full speed. Spreads can be slightly wider, and major pairs like EUR/USD or GBP/USD tend to drift rather than trend decisively.

For traders in Dhaka (UTC+6), the Sydney session runs from around 04:00 to 13:00 local time. It is accessible if you are an early riser, but do not expect the kind of movement that suits momentum strategies.

Tokyo Session

Tokyo is where Asian market hours really get going. Volume picks up considerably, especially on major currency pairs involving JPY: USD/JPY, EUR/JPY, and AUD/JPY are the most active.

The session overlaps briefly with Sydney in its early phase, creating a small but useful window of increased liquidity for Asia-Pacific pairs. Moves tend to be more measured than during London or New York hours, which makes Tokyo appealing for traders who prefer defined ranges over sharp breakouts.

For Dhaka-based traders, Tokyo runs from around 06:00 to 15:00 local time, a reasonable daytime window especially for JPY pairs or quieter, more structured conditions.

One thing worth noting: the Bank of Japan and other Asian central banks sometimes intervene in currency markets during these hours, which can cause sudden sharp moves on JPY pairs specifically. Keep an eye on the economic calendar during this session.

London Session

London is the largest forex trading centre in the world by volume, accounting for roughly 38% of all global forex turnover according to BIS data. When London opens, everything changes. Spreads tighten, volume surges, and major pairs start moving with real conviction.

EUR/USD, GBP/USD, EUR/GBP, and USD/CHF are particularly active during London hours. Institutional order flow from European banks and asset managers hits the market throughout the morning, often setting the directional tone for the rest of the day.

Bid-ask spreads on major pairs during peak London hours are typically at their narrowest, which directly reduces your cost per trade. The difference between trading during London hours versus a quiet session can be significant if you are paying close attention to forex spreads.

For traders in Dhaka (UTC+6), the London session runs from 13:00 to 22:00 local time, a genuinely convenient afternoon and evening window for traders who work during the day.

New York Session

New York carries the baton from London and brings its own character to the market. US economic data releases, Federal Reserve commentary, and American institutional trading all hit during these hours, creating some of the sharpest intraday moves of the day.

USD pairs dominate. EUR/USD, USD/JPY, USD/CAD, and GBP/USD all see heavy volume. US employment reports, CPI figures, and FOMC minutes regularly land during New York hours, and the market tends to react fast.

For traders in Dhaka, New York runs from 19:00 to 04:00 local time. The earlier part of this window (19:00 to 23:00 local) overlaps with the tail end of London, which is where conditions are at their best.

Session Overlaps: Where the Real Action Happens

Overlaps are the windows where two major sessions run simultaneously. They concentrate liquidity, compress spreads further, and generate more consistent price movement than any single session alone.

Sydney-Tokyo Overlap (03:00 to 07:00 UTC)

A modest overlap, mainly relevant for AUD, NZD, and JPY pairs. Volume is not dramatic, but conditions are more active than pure Sydney hours. Useful for Asia-Pacific focused traders.

Tokyo-London Overlap (07:00 to 09:00 UTC)

This two-hour window can be surprisingly active, particularly around the London open at 08:00 UTC. European traders coming online often react to positions built overnight in Asia, which can trigger sharp moves on EUR/JPY and GBP/JPY.

London-New York Overlap (13:00 to 17:00 UTC)

EUR/USD typically sees its highest daily volume during this window. Big institutional orders, US economic data releases, and London traders adjusting or closing positions all arrive at once. For day traders, this overlap is the primary hunting ground.

A Practical Session Reference by UTC

How Sessions Affect Spreads, Volatility, and Strategy

Session timing does not just affect when to trade. It affects how you trade, what your costs look like, and which strategies are even viable.

Spreads are tightest during London and the London-New York overlap. During low-volume sessions like Sydney, the same broker may quote wider spreads on EUR/USD simply because fewer market makers are actively competing. Understanding how forex spreads work and how they shift across sessions helps you calculate true trading costs more accurately.

Volatility follows session logic too. Breakout strategies that rely on sharp directional moves tend to work better during London open or during the overlap. Range-based strategies often perform better during quieter Asian sessions when price tends to oscillate rather than trend.

News events are session-specific. US economic releases (NFP, CPI, Fed statements) hit during New York hours. European data drops at the London open. Japanese data tends to arrive before or during Tokyo hours. Using forex indicators and candlestick patterns becomes far more reliable when you also account for when those sessions are active.

Matching Sessions to Your Trading Strategy

There is no universal best session. The right one depends on what you are trying to do.

• Breakout or momentum trading: The London open (07:00-09:00 UTC) and the London-New York overlap (13:00-17:00 UTC) are your best windows. Pair this approach with forex trading strategies built for trending conditions.
• Range trading: Tokyo and late New York (after 18:00 UTC) often produce tighter, more predictable ranges, well suited to strategies built around defined support and resistance.
• Swing trading: Session timing matters less for entries, but stop-loss and take-profit placement becomes especially important when holding through session transitions.
• New traders: Starting with a demo account during London or overlap hours gives you realistic conditions to practice in before encountering the quieter, more erratic behaviour of off-peak sessions.

What Happens on Weekends and Public Holidays

The forex market is closed from Friday evening (22:00 UTC) until Sunday evening (22:00 UTC). Any positions held over the weekend are exposed to gap risk: if major news breaks while markets are closed, price can open significantly higher or lower than where it closed on Friday.

This is particularly relevant for traders using tight stop-losses. A gap can bypass a stop entirely. Understanding forex risk management in the context of weekend gaps is something every trader holding positions into Friday close should think through.

Public holidays reduce liquidity even during normally active sessions. Check your broker’s published holiday schedule and factor it into your planning.

A Note on Daylight Saving Time

The session times listed above are standard UTC times. But London, New York, Sydney, and Tokyo all observe daylight saving at different times of year, and not all of them shift on the same date. This means the overlap windows shift slightly depending on the time of year.

For example, when the US shifts to summer time but Europe has not yet done so, the London-New York overlap temporarily shrinks. Most platforms include a built-in session clock that handles this automatically. You can cross-reference against a reliable forex market hours reference when in doubt.

For Traders Based in South Asia

If you are trading from Dhaka (UTC+6), here is how the sessions map to your local clock:

The most practical window for most Dhaka-based traders is the London session and especially its overlap with New York, which runs through the evening hours. This gives access to the highest-volume, tightest-spread conditions of the entire trading week at a time that fits a normal waking schedule.

Avoid the trap of trading just because the market is technically open. The Sydney-only window (roughly 04:00 to 06:00 local) has genuinely thin liquidity on most pairs, and the cost of a bad trade in those conditions is higher than most traders expect.

Common Mistakes Around Session Trading

• Trading without checking the session. A trader who opens a EUR/USD position at 02:00 UTC is in the quietest part of the day. Volume is minimal, spreads are wider, and even a small order can push price around.
• Ignoring the news calendar. Session awareness and economic calendar awareness go together. A news release during New York hours can wipe out a range trade that looked perfectly reasonable three minutes earlier.
• Holding positions into weekend close carelessly. Traders who leave positions open through Friday without a clear plan for gap risk are taking on exposure they have not consciously priced.
• Forcing trades in your preferred session even when conditions do not suit. Your session preference should align with your strategy, not just your schedule.
• Overtiring yourself. The market being open 24 hours is not an invitation to trade 24 hours. Set a schedule that fits your life and stick to it.

Putting It Together

The forex market runs continuously through the week, but it is not a flat, featureless 120 hours. It has shape: quiet patches, active windows, and peak overlap zones where most of the serious price action concentrates.

Sydney starts things gently. Tokyo brings steady Asian flow. London ignites real volume and institutional participation. New York amplifies it further, especially when US data hits. The London-New York overlap is the centrepiece, where liquidity peaks and major pairs move with the most conviction.

Your job as a trader is to know which session fits your strategy, match your schedule to it as much as possible, and resist the temptation to trade simply because the market is technically open.

If you are still getting familiar with how currency pairs behave across sessions, spending time with forex charts during different windows will build that intuition faster than most other approaches. Watch how EUR/USD behaves at 02:00 UTC versus 14:00 UTC. The difference is noticeable immediately.

Session awareness will not make every trade profitable. But it will stop you from fighting the market at the worst possible times. If you are new to all of this, the beginner’s guide to forex trading is a solid next step from here.
