London session

London is the centre of gravity of the foreign exchange market: by settlement volume it handles more than any other centre, and the hours it is open carry the majority of the day’s movement in EUR, GBP and CHF pairs.

When the London session runs

The London session is defined by the hours London keeps: 08:00 to 17:00 local. That never changes. What changes is where those hours land on your clock.

What the London session is like

The open is the sharpest scheduled liquidity event of the European day. Ranges expand quickly in the first hour.
European data — inflation prints, central bank speakers, PMIs — lands during these hours.
The last four hours run alongside New York, and that overlap is the busiest window of the entire 24-hour cycle.

What else is open while it runs

Measured on a northern-summer day. The figures shift by an hour when the hemispheres fall out of step, which is exactly why the live clock above is the authority and this table is the summary.
Session	Hours shared	What that means
New York	4h	A long overlap: liquidity from both centres, and the deepest book of the day.
Sydney	none	No overlap — these two never trade at the same time.
Tokyo	none	No overlap — these two never trade at the same time.

London session in every major timezone

A row where the two columns match is a timezone that moves in step with London — or one where neither moves at all.
