One question, answered from the exchange notices.
Markets Open answers whether a calendar date is a trading day on the Chinese stock and futures exchanges — and whether there is a night session that evening — with every answer traceable to an official notice.
What it covers
Nine loaded calendars for 2026: Shanghai and Shenzhen stock exchanges; the Shanghai, INE, Dalian, Zhengzhou and Guangzhou futures exchanges; Hong Kong cash equities; and the London Metal Exchange. SGX, CME and ICE show representative product hours. The site answers calendar questions, not whether a session is live right now — for that, use FuturesClock ↗.
Who maintains it
Markets Open is an independent public reference maintained by the same Singapore-based team as FuturesClock. It is not affiliated with, endorsed by or operated on behalf of any exchange, broker or data vendor. The maintainer trades on these exchanges daily, which is why the night session and the holiday edges get first-class treatment.
How the data is handled
- Facts are restated from official notices and linked to them. Notice text is never reproduced.
- Each record carries the source URL, the source-check date and the human sign-off date; unknown is returned as null, never as closed.
- Where an official original could not be retrieved (DCE and CZCE annual notices), complete third-party reproductions were cross-checked against each other and against every holiday night notice, and the page says so.
- Corrections are logged on the changelog with the affected dates and the evidence.
