Trading hours by timezone
A geographic walk through the global trading day, from Sydney's first bell to New York's closing print.
The trading day begins on a Monday at the Australian Securities Exchange - Sydney is the easternmost major market - at 10:00 local. By the time New York closes on Friday at 16:00 ET, more than 120 cumulative hours have elapsed.
The Asian morning
Sydney opens first, then Tokyo and Seoul. About ninety minutes later, Hong Kong, Shanghai, Shenzhen and Taiwan start. Singapore and the ASEAN markets are open by 09:00 SGT. India opens last in the Asian block at 09:15 IST.
The European day
London opens at 08:00 GMT, an hour earlier than the rest of Europe. The Frankfurt-Paris-Amsterdam-Milan bloc opens at 09:00 local - a meaningful overlap with closing hours in Asia.
The American afternoon
New York opens at 14:30 UTC in summer (13:30 in winter), as London hits its busiest period. From 13:30 to 16:30 UTC, London and New York are both open - the heaviest-volume window of the week.
The handover
At 21:00 UTC New York closes. There's a quiet two-hour gap before Sydney's bell rings again, and the pattern starts over.
