Trading Session

A trading session is one of the major regional windows that the 24-hour forex day is divided into — commonly Sydney, Tokyo (Asian), London (European), and New York (US) — each corresponding to peak business hours in that region. Different sessions bring different liquidity, volatility, and pair behaviour: the Asian session is often calmer and favours yen and Pacific-region pairs, while the London and New York sessions carry the bulk of volume on the majors. The overlaps, especially London–New York, concentrate the most activity and the tightest spreads, whereas the late hours and the weekend gap are thin. Many traders deliberately match their strategy to a session, since a method built for volatile overlap hours may behave very differently in quiet conditions. Tagging your trades by session is a simple way to discover when you actually trade best.

In plain English — The forex market runs 24 hours a day on weekdays, but activity is not even across the clock. It moves through regional sessions — broadly Sydney, Tokyo, London, and New York — each with its own pace, volume, and typical pairs. Liquidity and volatility peak when two big sessions overlap, especially London and New York. Knowing which session you are trading helps explain why spreads, ranges, and behaviour differ at different times.

The London–New York overlap (late morning to early afternoon UK time) is usually the busiest window for EUR/USD, with the tightest spreads and the largest moves. The quiet hours after New York closes are far thinner.
