Taiwan Stock Exchange (TWSE)
Taiwan's main equity venue, dominated by semiconductor manufacturers; its open data service publishes listed-company and market statistics without a key, which is unusual among exchanges.

Trading session local time · Asia/Taipei
Session hours and the settlement cycle are compiled by Finance Foundation from the venue’s own published trading calendar. These are exact and change-prone — an extended session or a moved auction dates a figure like this quickly — so each row below carries what two independently maintained open calendars say about the same venue. Verify against the exchange before relying on any of it operationally. Sources.
Two independently maintained open calendars return the same hours as we hold. Cross-check from exchange_calendars (Apache 2.0) and pandas_market_calendars (MIT); neither endorses this site.

Not the name this venue trades under. Taiwan Stock Exchange Corporation is the group; the entity above is the one the ISO 10383 registry binds XTAI to, and the one that legally runs this market. - Ultimate owner
- None above it — 臺灣證券交易所股份有限公司 is the top of its own ownership chain.
GLEIF records no parent for this entity (NON_CONSOLIDATING), so the operator is itself the top of the tree - Owner listed
- No. Not listed, and not freely transferable either: by statute its shares pass only to licensed securities firms. On its own last published breakdown, dated 31 July 2021, 1,308 holders of record split 22.47% to state-linked bodies and 75.99% to private enterprises, of which dedicated securities firms held 22.02%. Read those proportions with the date in mind — paid-in capital has more than doubled since, to NT$17.3bn at the October 2025 company registration, and any holder who did not take up their share of that increase will have been diluted.
