Market Calendar

​
What it returns

  • market session status for supported exchanges
  • timezone and session hours
  • coverage metadata showing whether the calendar is weekend-only or holiday-configured
  • confidence and status notes so callers can see when a session is only tentatively inferred
  • source URL provenance for each market

​
Coverage model

  • configured_holidays means OMNI has an explicit holiday map and weekend rules for the exchange
  • weekend_only means OMNI currently knows the exchange weekend pattern and regular hours but may not yet reflect every local holiday closure
  • confidence=tentative is returned when OMNI is inferring an open session from weekend-only coverage

​
Source inventory

  • XNYS: NYSE hours and holiday calendar
  • XNAS: Nasdaq holiday schedule
  • XLON: London Stock Exchange market hours
  • XTKS: Japan Exchange Group market calendar
  • XHKG: Hong Kong Exchanges trading hours
  • XTAE: Tel Aviv Stock Exchange trading hours
  • XSAU: Saudi Exchange trading hours

​
Rights and sync rules

  • public_source_documented means the exchange page and current usage posture have been reviewed and recorded in the source inventory
  • public_source_review_required means OMNI has the public source mapped, but local holiday coverage still needs explicit hardening before callers should assume full certainty
  • daily_midnight_local means the market should be regenerated automatically every local-market midnight
  • daily_manual_review means the public source is tracked, but holiday coverage still needs operator review or hardening before full automation

​
Sync posture

  • the endpoint is generated from OMNI’s exchange-source inventory
  • inventory export for ops: bun run ops:market-calendar-inventory
  • weekend-only exchanges are intentionally labeled as tentative on non-weekend weekdays until holiday coverage is hardened
