Live market state
The home timeline owns open/closed state, next transition and regular sessions.
Open the live clock →Contract specifications
Each contract page is the canonical owner of size, tick, tick value, expiry rule and upcoming dates.
Browse contracts →Expiry overview
The expiry directory groups events by date and links to monthly calendars and individual contract months. Each date distinguishes official checks, rule calculations and provisional schedules.

Source and review records
Each record identifies its official-exchange source, review date, review state and public-reference rights state. Sources appear on contract pages and expiry events. Retrieval dates do not replace effective dates, and a page update does not mean every source was reviewed that day.
A source-compliance self-review (publisher terms and citation practice checked source by source) was completed and archived on 2026-08-20.
| Field | Evidence | Publish rule |
|---|---|---|
| Size, tick and tick value | Official contract-specification page | Source and rights state accepted |
| Expiry rule | Official rulebook or contract guide | Traceable rule text and review date |
| Front-contract dates | Current schedule, or an accepted rule calculation | Must say confirmed or rule-based estimate |
Current review state: Accepted· Rights state: Approved for public reference· Latest review: 2026-11-09
03 · DATE STATUS
Confirmed and rule-based are different states
- Official date checked
- The exact contract and event match an official date with a recorded check date.
- Rule calculated
- Calculated using reviewed rules and covered calendar inputs; not an individual official date check.
- Estimated
- Calculation depends on dates outside reviewed calendar coverage.
- Not verified / Not applicable
- Missing evidence is separate from an inapplicable event. No date is invented.
A rule-derived value must never be presented silently as confirmed. Re-open the linked official source before trading.
04 · FRESHNESS
Automated gates and review targets
- 120 daysMinimum future coverage; current coverage ends .
- 30 daysNear-term dates must carry an explicit review state.
- 80%Maintenance target for confirmed dates in the next 90 days; shortfalls remain visibly estimated.
- 90 daysMaximum record review age before the build gate alerts.
05 · CORRECTIONS
How corrections are handled
Send the page URL, field to correct, official notice URL and notice date. The accepted value stays in place until the evidence is reviewed through a traceable change; external feedback never silently overwrites it.
