Forex Market Sessions: Sydney, Tokyo, London and New York Explained

11 min read

Understanding forex market sessions is essential for timing your trades effectively and avoiding costly low-liquidity conditions. Unlike centralized stock exchanges, forex trades 24 hours a day through four major financial centers around the world, each with distinct characteristics, active currency pairs, and volatility patterns. This guide provides a comprehensive breakdown of each session, their overlaps, and how to use session knowledge to improve your trading results.

The Sydney Session (10:00 PM - 7:00 AM UTC)

The Sydney session kicks off the trading week on Monday morning (Sunday evening in the US) and is the first major session to open each day. While Sydney is the smallest of the four major sessions by trading volume, contributing approximately 4-5% of daily forex volume, it plays an important role in establishing the opening tone for the week and setting early ranges that other sessions may later break.

During the Sydney session, AUD and NZD pairs are most active. This makes sense because the Reserve Bank of Australia, the Reserve Bank of New Zealand, and Australian economic data releases occur during this window. Pairs like AUD/USD, NZD/USD, and AUD/NZD tend to see their most meaningful movements during Sydney hours. Cross pairs involving AUD and NZD can also be relatively more liquid during this session compared to others.

The Sydney session overlaps with the end of the New York session (first hour) and with the Tokyo session (last few hours). The Tokyo-Sydney overlap (midnight to 7:00 AM UTC) is sometimes called the Asian session collectively. Price action during Sydney hours tends to establish consolidation ranges that the London session frequently breaks out of, making it useful for identifying key support and resistance levels.

The Tokyo Session (midnight - 9:00 AM UTC)

The Tokyo session represents approximately 10-12% of daily forex volume and is characterized by relatively orderly, range-bound price action. Japan is the third-largest economy in the world, and the Bank of Japan is one of the most active central banks, making JPY pairs the primary focus of this session. USD/JPY, EUR/JPY, GBP/JPY, and AUD/JPY are the most actively traded pairs during Tokyo hours.

The Tokyo session is known for a distinctive pattern: the Tokyo range. During the first few hours of the session, price typically establishes a range. This range becomes a reference point for breakout traders during the London open, as a break above or below the Tokyo range often signals the direction for the day. This Tokyo range breakout strategy is one of the most well-known and traded patterns in forex, precisely because it works often enough to be reliable while still requiring careful risk management.

Key Japanese economic data releases, including GDP, CPI, trade balance, and Bank of Japan policy decisions, occur during the Tokyo session and can cause significant volatility in JPY pairs. Asian equity market openings (Nikkei, Hang Seng, Shanghai Composite) also influence risk sentiment and JPY-cross pairs during this window.

The London Session (7:00 AM - 4:00 PM UTC)

The London session is the heavyweight champion of forex trading, contributing approximately 35% of daily volume. London has been the global center of foreign exchange for over a century, and it remains the most important session for most currency pairs. The session opens at 7:00 AM UTC with a burst of activity as European institutional orders are processed, often creating sharp moves in the first 30-60 minutes.

All major pairs are actively traded during the London session, with EUR/USD, GBP/USD, EUR/GBP, and EUR/CHF seeing their highest activity. European economic data releases, including ECB announcements, UK CPI, and German economic indicators, drive significant volatility. The London session is particularly well-suited for breakout and trend-following strategies because the strong institutional order flow tends to create sustained directional moves.

The first hour of the London session (7:00-8:00 AM UTC) is often called the "London open" and is characterized by sharp moves as overnight orders are filled and new institutional positions are established. Many day traders specifically focus on this opening hour for high-probability breakout setups. Use our Forex Market Hours tool to track session openings in real-time.

The New York Session (1:00 PM - 10:00 PM UTC)

The New York session accounts for roughly 20-25% of daily forex volume and is the primary driver of USD-pair volatility. The session opens at 1:00 PM UTC (8:00 AM EST), which coincides with the start of the US business day and the overlap with the London session. This overlap period is the most active in all of forex trading.

USD pairs dominate the New York session. EUR/USD, GBP/USD, USD/JPY, USD/CAD, and USD/CHF all see heavy institutional flow. Major US economic releases, including the Non-Farm Payrolls report (first Friday of each month), CPI, FOMC interest rate decisions, and GDP data, occur during the New York session and can create extreme volatility across virtually all currency pairs.

After the London session closes at 4:00 PM UTC, the New York-only session tends to see reduced liquidity. Price action often becomes more range-bound, and false breakouts are more common. The period from 8:00 PM to 10:00 PM UTC (3:00 PM to 5:00 PM EST) is particularly quiet as US traders wind down for the day, making it a poor time for day trading. The New York session closes at approximately 10:00 PM UTC, marking the end of the trading day and the beginning of the transition to the Sydney session.

The Critical Overlaps

Session overlaps are when the best trading conditions occur because two major financial centers are active simultaneously. The most important overlap is London-New York (1:00-6:00 PM UTC), which combines the two largest sessions and creates peak liquidity. The Tokyo-London overlap is brief (7:00-9:00 AM UTC) but can offer early direction for the day. The Sydney-Tokyo overlap forms the collective Asian session with moderate liquidity.

During overlaps, spreads are at their tightest, slippage is minimal, and price movements are most sustained and technically reliable. For day traders, these overlap windows should be the primary focus of trading activity. The cost savings from tighter spreads and the higher probability of genuine breakouts during overlaps can make the difference between a profitable and unprofitable strategy over the course of a year.

Frequently Asked Questions

What are the four forex trading sessions?

The forex market operates through four major trading sessions: Sydney (opens around 10:00 PM UTC), Tokyo (opens around midnight UTC), London (opens around 7:00 AM UTC), and New York (opens around 1:00 PM UTC). These sessions represent the business hours of the major financial centers in each region. As one session closes, the next one opens, and there are periods where sessions overlap, creating higher liquidity and volatility. The market trades continuously from Monday's Sydney open to Friday's New York close.

Which forex session is most profitable?

No single session is universally most profitable, as it depends on your strategy and the pairs you trade. However, the London session (especially the London-New York overlap from 1:00-6:00 PM UTC) is generally considered best for day traders because it offers the highest liquidity, tightest spreads and most sustained trends. The Tokyo session is best for JPY and AUD pairs and range-trading strategies. The New York session is best for USD-related volatility. For swing traders, any session can work as trades are held for days, making the entry session less critical.

What happens between the New York close and Sydney open?

Between the New York close (around 10:00 PM UTC) and the Sydney open (around 10:00 PM UTC on Sunday), there is a brief period where the market is essentially closed for the weekend. During the week, the transition from New York close to Asian open (Tokyo/Sydney) is the quietest period of the trading day. Liquidity drops significantly, spreads widen, and price action tends to be range-bound or choppy. This low-liquidity period (roughly 9:00 PM to midnight UTC) is generally a poor time for active trading, though it can be used for analysis and preparation for the upcoming sessions.

Why is the London-New York overlap so important?

The London-New York overlap (1:00-6:00 PM UTC) is when both European and American financial markets are simultaneously active, creating the deepest liquidity pool in the forex market. During these 5 hours, approximately 70% of all daily forex transactions occur. Major US economic releases (NFP, CPI, FOMC minutes) happen during this overlap, driving USD volatility. EUR/USD, GBP/USD and USD/JPY see their tightest spreads and most reliable trends during this window. Most professional day traders concentrate their activity within this overlap period.

Do forex sessions change with daylight saving time?

Yes, forex session times shift by approximately one hour when regions enter or exit daylight saving time (DST). The US and UK change clocks on different dates, creating temporary adjustments. For example, when the US has entered DST but the UK has not (or vice versa), the London-New York overlap shifts from its usual 5 hours to approximately 4 hours. Most brokers and platforms automatically adjust for these changes. Traders should be aware of the current session times during transition periods, as they can affect volatility patterns and session overlap timing.
