Trading sessions
Trading sessions are the working hours of the main financial centers: Asian, London and New York. Activity and volatility peak when the London and New York sessions overlap.
How it works
The currency market runs around the clock from Monday to Friday because trading moves from one time zone to the next. Roughly, in UTC during winter: Asia (Tokyo) 00:00–09:00, London 08:00–17:00, New York 13:00–22:00. In summer, daylight saving time moves London and New York one hour earlier.
The session matters because it sets liquidity, meaning how many participants are ready to buy and sell right now. When many banks and funds are active, spreads are tight and moves are bigger. In quiet hours price often drifts in a narrow range and the spread widens.
The busiest window is the London and New York overlap, about 13:00–17:00 UTC in winter. Many major US data releases land in it too. Crypto trades 24/7, but volume there also tends to rise during European and US hours.
EUR/USD may move only 20–30 pips in the Asian session and 60–80 pips once London and then New York open. A breakout strategy that works in European hours often gives false signals overnight in Asia.
You live in UTC−5 (US Eastern winter time). The London and New York overlap for you is roughly 8:00 to 12:00 local time. That is when spreads on the major pairs are usually tightest.
A common mistake is trading whenever it suits you and not understanding why price "won't move" or the spread is suddenly wide. Late at night in Europe, before weekends and on holidays liquidity is thin and false moves are more common. Look up the session hours in your own time zone, account for clock changes, and trade when your instrument is actually active.
