London session
The European trading session, roughly 08:00–16:30 UK time, and the busiest part of the day for most FX pairs.
Full explanation
The London session covers European business hours, broadly 08:00 to 16:30 UK time. London is the largest FX centre by volume, so this is when most currency pairs see their deepest liquidity, tightest spreads and largest share of the daily range.
The open is often the most active moment of the day. Orders accumulated during the quieter Asian hours arrive at once, which frequently produces a decisive move away from the overnight range — and equally frequently produces an initial move that reverses.
European economic releases — inflation, employment and confidence data, plus European Central Bank and Bank of England commentary — cluster in this session.
Why traders watch it
For most European-based traders the London session is the core opportunity of the day: enough movement to make a plan worthwhile, and enough liquidity for levels to behave predictably.
The Trading Plan is generated before London opens so you can prepare beforehand, and its Trading Windows normally centre on this session.
Trading considerations
- The first move after the open often reverses — let the opening range settle.
- Expect the day's largest share of movement between the open and the New York overlap.
- European data lands early; check the calendar before the open.

Asian session
The overnight session driven by Tokyo, Sydney, Hong Kong and Singapore, typically quieter and range-bound.
Clear direction
When one side is plainly in control: price makes progress one way and pullbacks are shallow.
Consolidation
A pause in which price moves tightly sideways, often after a strong move, while the market absorbs it.
First spike
The sharp, immediate move in the seconds after a release or a level breaks — usually the least reliable part of the whole move.
High-impact news
A scheduled release with a strong record of moving markets sharply — for example inflation, employment data or an interest-rate decision.
Holding a move
When price stays at its new level after a move instead of drifting back — the sign that the move was accepted.
