Trading session
A block of the trading day defined by which financial centres are active, and therefore how much liquidity is available.
Full explanation
The foreign exchange market trades around the clock on weekdays, but activity is not spread evenly. It moves with the working hours of the major financial centres, which traders group into the Asian, London and New York sessions.
Each session has a recognisable character. Liquidity, typical daily range, spreads and how cleanly price respects levels all change as centres open and close. The busiest period of all is the overlap when London and New York are both open.
Sessions are a description of conditions, not a rule about when to trade. They tell you what kind of market to expect at a given hour.
Why traders watch it
Choosing when to trade is as important as choosing what to trade. A strategy that needs movement will struggle in a quiet session; a strategy that needs orderly price action will struggle in the first minutes after a major open.
Today''s Trading Plan is organised around sessions: Trading Windows describe when conditions typically suit activity, and risk windows mark the periods to stand aside.
Trading considerations
- Match your strategy to the conditions the session actually provides.
- Spreads widen and liquidity thins at session handovers.
- Session times shift by an hour when clocks change; the platform shows times in UK time.

Liquidity
Liquidity describes how easily you can buy or sell without moving the price. Deep liquidity means tight spreads, reliable fills and orderly movement. Thin liquidity means wider spreads, slippage and sudden jumps. Liquidity varies through the day, peaking when London and New York overlap and thinning during the late Asian session, holidays and the minutes around major releases.
Volatility
Volatility describes how much price moves over a given period. High volatility means larger, faster swings and wider ranges; low volatility means quiet, compressed trading. Volatility is not direction — a market can be highly volatile while going nowhere. It rises around major news, session opens and central-bank decisions, and it decides how far stops and targets need to sit.
