Trading Fundamentals
The major forex sessions across Sydney, Tokyo, London, and New York, how trading activity and liquidity may vary throughout the day.
Forex is generally active from Sunday evening to Friday evening, following the major financial centres of Sydney, Tokyo, London, and New York. As one region's business day ends, another begins, creating a continuous flow of market activity. Understanding this rhythm can help participants identify when liquidity, volatility, and spreads may change.
The Sydney session opens the trading week and is often quieter than later sessions. Liquidity may be lower, and price movement may be more limited depending on market conditions. This session is commonly associated with AUD and NZD pairs, particularly when it overlaps with the Tokyo session.
The Tokyo session represents a major part of Asian trading activity. Liquidity may increase during this period, especially in JPY pairs and Asia-Pacific currencies. Price movement is often more moderate than during the European or US sessions, though news from China, Japan, or Australia can still affect volatility.
The London session is one of the most active periods in the forex market, with high participation from European financial centres. Major currency pairs involving EUR, GBP, and CHF may see increased activity during this session, and spreads on liquid pairs may be tighter depending on market conditions.
The New York session opens while London is still active, creating an important overlap period for forex trading. Major US economic releases often occur during this session and may affect liquidity, volatility, and USD-related pairs. Activity can also influence other major currency pairs depending on market conditions.
Session overlaps occur when two major trading sessions are open at the same time, most notably London/New York and Tokyo/London. These periods may be associated with higher liquidity, tighter spreads, and increased price movement, depending on market conditions and the instruments being traded.
Different sessions can have different liquidity, volatility, and spread conditions. Participants may review session activity alongside their trading plan, preferred instruments, and risk management approach. Low-liquidity periods, including around daily rollover, may be associated with wider spreads or less consistent execution.
