Sydney Session
The Sydney session is a conventional window of Australian participants' FX activity within the Asia-Pacific trading day. Retail weekly trading generally resumes on Sunday in New York time. UTC hours depend on daylight saving and the broker's schedule; the session does not guarantee the lowest volatility or dominance of particular pairs.
Illustrative example
How does it work in practice?
Suppose a broker resumes trading on a New York schedule while a trader tracks Sydney in UTC. Before Sunday, the trader checks the date, both time-zone offsets and the pair's first quoting time.
A case to work through
Sunday becomes Monday
A fictional schedule gives Sunday 17:00 at UTC−4; assume Sydney UTC+11.
- UTC time is Sunday 21:00.
- Adding 11 hours gives Monday 08:00 in Sydney.
What follows? Record the date alongside the time.
Example boundary: Offsets are assumptions; actual hours depend on broker and pair.
A useful distinction
Sydney Session / Tokyo Session
Tokyo and Sydney are different activity windows; neither alone sets server time.
