How Price Action Differs by Trading Session

In FX trading, “when” you trade is just as important as “what” and “how” you trade. The market runs 24 hours a day, but price action varies greatly depending on the time of day. Liquidity, volatility and trend strength all change from session to session, so understanding these characteristics lets you trade more effectively. In this article, I explain the characteristics of the major trading sessions and how to make use of them.

Understanding the 24-Hour Structure of the FX Market

The FX market operates almost 24 hours a day, following the hours when the world’s major financial centers are open. The main trading sessions are as follows (in Japan time).

The Main Trading Sessions

• Tokyo (Asian) session: around 9 am–5 pm JST (00:00–08:00 UTC)
• London (European) session: around 4 pm–1 am JST (07:00–16:00 UTC)
• New York (US) session: around 9 pm–6 am the next morning JST (12:00–21:00 UTC)

These hours show the core time of each session, but actual market activity often starts before each open. For example, the Tokyo session officially starts at 9 am JST (00:00 UTC), but in practice it starts to get active from around 7 am JST (22:00 UTC the previous day).

Why Session Overlaps Matter

Especially important are the hours when different sessions overlap.

• Asia–Europe overlap: around 3 pm–5 pm JST (06:00–08:00 UTC)
• Europe–US overlap: around 9 pm–1 am JST (12:00–16:00 UTC)

These overlaps have high liquidity and tend to produce large moves. The Europe–US overlap in particular is when the world’s two largest financial markets are both active, making it the period with the highest liquidity and the greatest tendency for large moves.

Characteristics and Tendencies of Each Session

Tokyo (Asian) Session

• Hours: around 9 am–5 pm JST (00:00–08:00 UTC) (same in summer and winter time)
• Participants: mainly financial institutions, companies and individual investors in Asia, such as Japan, Australia, Singapore and Hong Kong
• Characteristics:
  • Relatively small moves; prone to ranging markets
  • Tends to react to Japanese economic indicators
  • Asian currencies such as USD/JPY, AUD/USD and AUD/JPY tend to move
  • Easily influenced by real demand from Japanese exporters and importers

In the Tokyo session, the activity of Japanese investors and companies in particular affects the yen. Moves are often smaller than in the European and US sessions, but the market can move significantly around important data releases and events.

London (European) Session

• Hours: around 4 pm–1 am JST (07:00–16:00 UTC) (one hour later in winter time)
• Participants: European financial institutions, hedge funds, companies and central banks in the UK, Germany, France and elsewhere
• Characteristics:
  • The largest FX trading volume in the world
  • Active price action; trends form easily
  • European pairs such as EUR/USD, GBP/USD and GBP/JPY tend to move
  • Reacts sensitively to European economic indicators and ECB and Bank of England policy announcements

The London session has high liquidity, and many trends start during these hours. Large moves often occur especially when there are important data releases.

New York (US) Session

• Hours: around 9 pm–6 am the next morning JST (12:00–21:00 UTC) (one hour later in winter time)
• Participants: US financial institutions, hedge funds, companies, the Fed and others
• Characteristics:
  • Reacts strongly to US economic indicators
  • Highly correlated with the US stock market
  • Volatility gradually declines late at night (Japan time)
  • USD pairs such as USD/JPY, EUR/USD and USD/CAD tend to move

The New York session reacts most sensitively to US data releases. Large moves often occur especially around FOMC (Federal Open Market Committee) policy announcements and NFP (nonfarm payrolls) releases.

Trading Strategies by Session

Once you understand the characteristics of each session, it is important to think about trading strategies that match them.

Trading Strategy for the Tokyo Session

• Range breakout strategy: aim for a breakout of the top or bottom of the Tokyo session range
• Asian pairs: focus on USD/JPY, AUD/JPY, AUD/USD and similar pairs
• Key economic indicators: watch Japan’s composite index of business conditions, trade balance, BoJ policy announcements and so on

For example, a common pattern is a range forming early in the Tokyo session and then breaking after 3 pm JST (06:00 UTC), when European players enter the market.

Trading Strategy for the London Session

• Trend following strategy: new trends tend to form in the London session, so riding in the direction of that trend is effective
• European pairs: focus on European pairs such as EUR/USD, GBP/USD and GBP/JPY
• Key economic indicators: watch eurozone PMI, UK GDP, ECB policy announcements and so on

For example, following trends that develop during the London session (around 4 pm–1 am JST (07:00–16:00 UTC)) or riding the direction set after European data releases are effective strategies. Also, orders from institutional investors and companies concentrate around the “London fix” (WM/Reuters fix) at around midnight JST (15:00 UTC) (16:00 London time), so large moves can occur around that time.

Trading Strategy for the New York Session

• Data release trading: target the price action after US data releases
• USD pairs: focus on EUR/USD, USD/JPY, USD/CAD and similar pairs
• Key economic indicators: watch US NFP (nonfarm payrolls), GDP, the FOMC and so on

For example, trends tend to form after important US data releases, and trading in that direction is effective. NFP days (the first Friday of every month) in particular can be expected to bring large moves.
However, avoid trading right on the data release. The basic rule is to get in after the chart has settled down following the release.

How Spread and Liquidity Change Through the Day

The spread (the difference between the bid and ask prices) and liquidity also change significantly depending on the session.

When Spreads Are Tight

• The overlap of the London session and the New York session (around 9 pm–1 am JST (12:00–16:00 UTC))
• The core time of the Tokyo session (around 10 am–3 pm JST (01:00–06:00 UTC))

When Spreads Widen

• After the New York session closes (after 6 am JST (21:00 UTC the previous day))
• Before the weekend (late Friday night) and at the start of the week (early Monday morning)
• Immediately before and after important data releases
• Holiday seasons such as Christmas and the year-end/New Year period

When liquidity drops, not only do spreads widen, but slippage (the difference between the order price and the fill price) also becomes more likely. Be especially careful at the start of the week, as gaps (price jumps) can occur in response to weekend news. When spreads widen, you often cannot manage risk properly, so staying out of the market is a good choice.

The Best Trading Hours for Each Currency Pair

Each currency pair is most active at different times of the day.

USD/JPY

• Best trading hours: Tokyo session to New York session
• Characteristics: starts moving in the morning Tokyo session and often shows relatively steady price action throughout the day until the New York session

EUR/USD

• Best trading hours: London session to New York session
• Characteristics: reacts sensitively to both European and US economic indicators and moves most during the overlap of the two sessions

GBP/JPY

• Best trading hours: London session
• Characteristics: high volatility; often shows large moves, especially during the London session

By understanding these characteristics and choosing the best hours for the pair you want to trade, you can trade more efficiently.

A Practical Trade Example Using Session Analysis

Let’s look at a trading strategy that takes the time of day into account, using GBP/JPY, the pair recommended on this site, as an example.

London Open Strategy

Around 4 pm JST (07:00 UTC), when the London market opens, is when GBP/JPY starts to move. Before this time, check the GBP/JPY chart and look for a setup like the following.

1. Check the ranging market carried over from the previous day
2. Identify the support/resistance lines formed before the London open
3. Wait for a breakout after the London session opens
4. Enter in the direction of the breakout (from a pullback or retracement on the lower timeframe)

In particular, a breakout of the range formed during the Tokyo session before the London open often indicates the direction of the subsequent trend.

Summary: Make the Trading Sessions Work for You

In FX trading, understanding the characteristics of each trading session is very important. By grasping how market participants, liquidity and volatility change through the day, you can trade more effectively.

However, the core of FX trading is Dow Theory, multi-timeframe analysis and horizontal levels.
When backtesting on historical charts, you can get results using technical analysis alone, without paying attention to the Tokyo session or the European session.
Treat the differences between sessions as an extra factor only, use them as a reference when deciding trading hours that fit your lifestyle, and be careful not to neglect the core.
