Sessions and changing liquidity
The market can feel quiet at one hour and crowded at another. Let’s ask who is active, rather than trust the clock alone.
Relate trading conditions to time while accounting for daylight-saving changes.
Forex activity moves between financial centres as their working days overlap. Asian, European and North American sessions are useful descriptions of activity, not separate markets with guaranteed daily behaviours. A session name does not tell you which direction a currency will move.
Liquidity and volatility are different. Liquidity concerns the ability to transact size at available prices; volatility describes how much price changes. Active periods can still produce abrupt moves, while quiet periods can contain wide spreads and difficult execution.
Use a calendar that displays an explicit timezone. London and New York daylight-saving changes can shift session timing in Sri Lanka, which does not change its clocks. Check holidays, broker maintenance and product hours as well as familiar opening labels.
Let’s use numbers · hypothetical example
A hypothetical event is listed at 13:00 UTC. In Sri Lanka, UTC+5:30, it is 18:30. If the organiser changes the UTC event time, recalculate rather than reusing yesterday's local time.
Keep in mind
Do not treat fixed screenshots of session hours as a permanent schedule or assume every broker stays open continuously.
Your turn
Compare spread and five-minute ranges at two demo observation times; record date, timezone and any scheduled news.
A quick check before we move on
Why can a session's Sri Lankan time change?
- Sri Lanka changes clocks every weekend
- The pair changes its base currency
- The foreign centre may change its clocks for daylight saving
Check answer
The foreign centre may change its clocks for daylight saving Daylight-saving rules abroad can change the time difference even when Sri Lanka's own offset stays constant.
