#market-status

Live trading hours and open/closed status for the world's major stock exchanges, computed on demand from the current time in each exchange's own time zone — no key, nothing cached. Find whether one exchange is trading right now, its local time, regular hours, lunch break and the minutes until it next opens or closes; get the live status of every covered exchange; or list only the exchanges trading right now. Daylight-saving is handled automatically. A market-clock layer — distinct from FX-session and exchange-registry tools: for 17 stock exchanges (NYSE, Nasdaq, LSE, Euronext, Xetra, TSE, HKEX, SSE and more) it answers "is this market open and when does it change?". Note: public holidays are not accounted for.

Live forex market-hours layer — a real-time read on which foreign-exchange trading sessions are open right now and where the liquidity is. The 24-hour forex market runs as a relay of four regional sessions — Sydney, Tokyo, London and New York — and this computes, from the current clock and each financial centre's own timezone (daylight-saving handled automatically), whether each session is open, its local time, and its standard open and close in both local time and UTC. It surfaces the active session overlaps that traders care about — above all the London–New York overlap, the most liquid window of the day — reports whether the overall market is open (it closes over the weekend), and gives a world-clock of the four centres. Deterministic and always live, no key. Distinct from FX rate, strength, volatility, seasonality and signal APIs — this is the market-hours layer for forex, trading and dashboard apps.
