A complete, practical guide to Forex Factory sessions—what they are, how to use the session indicator tool effectively, when and how to apply session insights to your trading strategy, and the risks you must manage when trading across different market sessions.
Forex Factory sessions refer to the session indicator feature on the popular financial news and data website Forex Factory. The tool provides a visual, real-time representation of the four major forex trading sessions—Sydney, Tokyo, London, and New York—displaying their active periods, overlaps, and closed times directly on the website's interface.
Forex Factory is one of the most widely used resources among retail forex traders, known for its economic calendar, market data, and community forums. The session indicator is a simple but powerful tool that helps traders quickly understand which markets are open, when liquidity is at its highest, and which currency pairs are likely to be most active at any given time.
The session indicator is displayed prominently on the Forex Factory homepage and on other pages throughout the site. It uses a colour-coded system to show the current status of each session, with distinct colours representing each of the four major trading centres. The tool updates in real time, reflecting the 24-hour nature of the forex market.
According to the Bank for International Settlements (BIS) Triennial Central Bank Survey, the forex market's daily turnover exceeds $7.5 trillion, with trading activity concentrated during the overlapping periods of the major sessions. The Forex Factory session indicator helps traders visualise these periods of heightened activity and align their trading accordingly.
The session indicator provides an at-a-glance view of market conditions, enabling traders to make faster, more informed decisions about when to trade. By showing which sessions are active and when overlaps occur, it helps traders identify periods of maximum liquidity and volatility, as well as quieter periods that may be better suited for certain strategies or for taking a break from active trading.
The Forex Factory session indicator is a simple yet effective visual tool. Here's how it works in practice:
The indicator displays a horizontal timeline representing the 24-hour trading day. Each of the four major sessions is shown as a coloured bar or block on this timeline. The length and position of each bar correspond to the standard trading hours of that session in GMT (Greenwich Mean Time).
The indicator updates automatically every few seconds to reflect the current time. As the market moves through the day, the active session bar moves along the timeline, providing a continuous visual representation of which session is currently open.
When two sessions overlap, the indicator shows both bars active simultaneously, often with a combined colour or distinct visual marker. The London-New York overlap (13:00–17:00 GMT) is the most significant overlap and is clearly highlighted on the tool.
The tool typically displays the time remaining in the current session, helping traders plan their trading activities around session closures and upcoming overlaps.
The indicator marks the exact opening and closing times of each session, allowing traders to see exactly when liquidity conditions are about to change.
The session times displayed on Forex Factory are based on standard GMT offsets, but they are affected by daylight saving time (DST) changes in certain regions. Forex Factory typically adjusts for DST automatically based on the current date, but it is always advisable to verify session times with your broker during DST transition periods to ensure accuracy.
Forex Factory uses a distinct colour-coding system to differentiate between the four major trading sessions. The colours are consistent across the platform, making it easy to identify which session is active at a glance.
The Sydney session is typically represented by a light blue or grey colour. This session opens the trading week and is the quietest of the four major sessions, with lower liquidity and modest volatility.
The Tokyo session is shown in yellow or orange. This session is the second major session to open and is characterised by its focus on yen pairs and moderate volatility.
The London session is represented by a blue colour. This is the largest and most liquid session, accounting for approximately 30–35% of global forex volume. Blue is used to signify the importance of this session.
The New York session is shown in red. This session is the second largest and is known for its high liquidity and volatility, particularly during its overlap with the London session.
During session overlaps, the colours combine or appear side by side. For example, during the London-New York overlap, both blue (London) and red (New York) will be visible simultaneously, indicating the most active trading period of the day.
Knowing the session colours allows you to instantly assess market conditions as soon as you open Forex Factory. A quick glance tells you which session is driving the market, which pairs are likely to be most active, and whether you are trading in a high-liquidity or low-liquidity period.
The Forex Factory session indicator serves a variety of practical purposes for traders at all experience levels. Here are the most common use cases:
The primary use case is identifying when the market is most active. The session indicator helps traders pinpoint the London-New York overlap (13:00–17:00 GMT), which offers the tightest spreads, highest liquidity, and strongest trends. For traders who prefer quieter conditions, the Asian session may be more suitable.
Traders can use the session indicator to plan their daily trading schedules around their preferred sessions. By knowing when sessions open and close, traders can allocate their time effectively and avoid periods of low liquidity.
Different sessions favour different currency pairs. The session indicator helps traders choose pairs that are most active during their trading hours. For example, during the Tokyo session, yen pairs (USD/JPY, EUR/JPY, GBP/JPY) are most active, while during the London session, European pairs (EUR/USD, GBP/USD, EUR/GBP) dominate.
The indicator highlights the "dead zones" between sessions—periods when liquidity is thin and spreads are wide. Traders can use this information to avoid trading during these periods, reducing the risk of slippage and unfavourable execution.
Session overlaps, particularly the London-New York overlap, are ideal for scalping and day trading strategies due to the high liquidity and volatility. The session indicator helps traders time their entries during these high-activity windows.
Understanding which session is active provides context for economic data releases. For example, U.S. data releases during the New York session can cause significant movements in USD pairs, while European data releases during the London session affect EUR and GBP pairs.
While the Forex Factory session indicator provides valuable information, evaluating which session is suitable for your trading requires consideration of several factors:
If you are a scalper or day trader who thrives on volatility, the London and New York sessions (especially their overlap) are ideal. If you are a range trader or prefer lower volatility, the Asian session may be more suitable. Evaluate the typical volatility of each session against your strategy's requirements.
Higher liquidity generally means tighter spreads and more efficient execution. The London and New York sessions offer the best liquidity, while the Asian session has moderate liquidity and the Sydney session the lowest. Consider how spread width affects your trading costs.
Your physical location and daily routine are practical considerations. The Forex Factory session indicator displays times in GMT, but you must convert these to your local time zone. Choose sessions that align with your available trading hours and natural energy levels.
Evaluate which pairs you intend to trade and match them to the sessions where they are most active. For example, if you primarily trade AUD/USD, the Sydney and Tokyo sessions are more relevant than the New York session.
Forex Factory also provides an economic calendar. Integrating the session indicator with the calendar allows you to see when high-impact news is scheduled during each session, helping you decide whether to trade around those events or stay out.
The Commodity Futures Trading Commission (CFTC) and National Futures Association (NFA) provide investor education on the importance of understanding market conditions and the risks of trading during low-liquidity periods. The Federal Reserve publishes daily foreign exchange rates, providing additional context for session-specific movements. Always verify market conditions with your broker and consult official sources for the latest data.
The table below provides a side-by-side comparison of the four major forex sessions as displayed on Forex Factory. It includes their colour codes, times, and key characteristics.
| Session | Colour | GMT Time | Volume Share | Liquidity | Volatility | Key Pairs |

| London-New York Overlap | Blue + Red | 13:00–17:00 | ~50% | Very High | Very High | Major pairs |
Colours and times are based on the standard Forex Factory display. Actual session times may vary during daylight saving periods. Always verify current times with the Forex Factory platform or your broker.
Use this checklist to make the most of the Forex Factory session indicator and integrate session awareness into your trading routine.
Elena wakes up at 06:30 local time (06:30 GMT). She opens Forex Factory and sees that the Tokyo session is still active (yellow colour) with about 2.5 hours remaining before the London session opens at 08:00 GMT. The Sydney session has already closed.
Elena notes that the London-New York overlap will occur later in the day from 13:00 to 17:00 GMT, which she has identified as her most profitable trading window. She uses the morning hours (08:00–12:00 GMT) to analyse the market, review her watchlist, and prepare for the overlap.
At 12:45 GMT, Elena checks the session indicator again. The London session is active (blue), and the New York session is about to open in 15 minutes. She prepares her trading platform, sets up her charts, and reviews key levels on EUR/USD and GBP/USD—the pairs she trades most during this overlap.
At 13:00 GMT, the New York session opens (red appears alongside blue). Elena executes her first trade of the day—a long position on EUR/USD based on a breakout pattern. The trade moves in her favour, and she closes it 45 minutes later with a 25-pip profit.
Throughout the overlap, Elena continues to monitor the session indicator to stay aware of how much time remains in the overlap. She notes that volatility tends to pick up around the release of U.S. economic data at 13:30 GMT, so she adjusts her position sizes accordingly. She finishes the day with three profitable trades and one small loss.
At 17:00 GMT, the London session closes, but the New York session remains active. Elena sees the blue bar disappear and the red bar continue alone. She decides to stop trading for the day, as she prefers the higher liquidity of the overlap period.
Elena's systematic use of the Forex Factory session indicator has helped her maintain discipline, avoid low-liquidity periods, and focus her trading on the hours when she performs best.
Reality: Session times shift by one hour during daylight saving time (DST) transitions in certain regions. Forex Factory adjusts for DST, but the times displayed may not always align perfectly with your local time zone without proper time zone configuration.
Reality: The forex market is open 24 hours a day, five days a week. Trading is possible at any time, but liquidity and spread conditions vary significantly. The session indicator helps you choose the best times, but trading outside active sessions is still possible.
Reality: While the London session is highly volatile, the London-New York overlap is actually the most volatile period. The New York session can also be more volatile than London during major U.S. data releases.
Reality: The session indicator shows market hours, but it does not show economic data releases. For a complete picture, you should use both the session indicator and the economic calendar together.
Reality: Different pairs are more active in different sessions based on the financial centres involved. For example, AUD/NZD is most active during the Sydney session, while USD/CAD is most active during the New York session.
Reality: The colour-coding system is specific to Forex Factory. Other platforms and brokers may use different colours for their session indicators. Always check the legend on the specific platform you are using.
While the Forex Factory session indicator is a valuable tool, there are risks associated with trading across different sessions. The following controls can help you manage these risks:
Even during overlaps, liquidity can be uneven, particularly in the first few minutes after a session opens. This can lead to unexpected slippage or wider spreads. Mitigation: Wait 15–30 minutes after a session opens before placing trades to allow liquidity to stabilise. Use limit orders where possible.
Daylight saving time changes can shift session times, causing confusion if you are not aware of the adjustments. Mitigation: Always verify session times with your broker during DST transition periods (March and November). Check the time zone settings on Forex Factory to ensure they match your location.
If you are not familiar with the colour-coding system, you may misinterpret which session is active, leading to poor trading decisions. Mitigation: Familiarise yourself with the Forex Factory colour scheme and check the legend or tooltip on the website if you are unsure.
The periods between sessions (22:00–00:00 GMT and 17:00–22:00 GMT) are low-liquidity "dead zones" where spreads widen and price action can be erratic. Mitigation: Avoid trading during these periods. Use the session indicator to identify these quiet times and take them as opportunities for analysis rather than active trading.
The session indicator is a guide, not a definitive source of market conditions. Broker-specific factors, market news, and geopolitical events can override normal session characteristics. Mitigation: Use the session indicator as one tool among many. Combine it with price action analysis, the economic calendar, and real-time market data.
The session indicator does not account for market holidays, which can significantly reduce liquidity even during normally active sessions. Mitigation: Check the Forex Factory calendar for holidays in major financial centres (UK, US, Japan, Australia) and adjust your trading plans accordingly.
