Shows which global trading sessions are open right now from your local time zone.
How this is calculated
Every window is defined by local clock times in its own IANA time zone, so daylight saving is applied automatically.
Tokyo 09:00–18:00 Asia/Tokyo · London 08:00–16:30 Europe/London · New York 09:30–16:00 America/New_York.
Killzones are defined in America/New_York: Asia 20:00–00:00, London 02:00–05:00, New York AM 08:30–11:00, New York PM 13:30–16:00.
The No Trade Zone is defined in America/Chicago as 06:30–08:00.
A session is open when the current moment, converted into that session's zone, falls inside its window on a weekday.
Worked example
At 14:00 in New York, the New York session window of 09:30–16:00 contains the current local time, so New York is marked open.
The same moment is 19:00 in London, which is after the 16:30 close, so London is marked closed.
The New York PM killzone runs 13:30–16:00 New York time, so it is active and the countdown shows the time remaining until 16:00.
Understanding global trading sessions
Market activity concentrates around the hours when major financial centres are at work. Splitting the day into Tokyo, London and New York sessions is a convention for describing where that activity sits, not an exchange calendar.
Because every window here is defined in local clock time inside its own time zone, the gaps between regions shift automatically through daylight saving transitions. Regions change clocks on different dates, so the overlap between London and New York widens and narrows a few times a year.
Killzones are narrower sub-windows within the session day that some intraday approaches reference. They are descriptive labels for periods of the clock, not signals, and they carry no directional meaning on their own.
Holidays, half-days and product-specific hours are not modelled. Individual exchanges publish their own calendars, and futures and spot forex hours differ from equity cash hours.
Frequently asked questions
Which time zone does the clock use?
It reads your browser time zone by default and lets you override it with New York, Chicago, London, Tokyo or UTC. Every window is still evaluated in its own home time zone.
Does the clock adjust for daylight saving?
Yes. Sessions are defined by local clock times in named IANA zones, so transitions in each region are applied automatically rather than being hardcoded as UTC offsets.
What is a killzone?
A narrower window inside the trading day that some intraday methods reference, defined here in New York time. It describes a period of the clock and is not a signal.
What is the No Trade Zone?
A 06:30–08:00 Chicago window covering the pre-open period. It marks a stretch that some traders choose to sit out; it does not indicate market direction.
Are these exact exchange hours?
No. They are the conventional session windows. Exchanges publish their own calendars, which include holidays, half-days and product-specific hours.
