max_pain_expiry_dte

Calendar days from the session to the monthly expiry max_pain_distance_pct was computed on: expiry = as_of_date + value. Between 7 (the roll floor) and 120 (the table's DTE limit). A LABEL, NOT A STATISTIC: it saws from ~35 down to 7 and resets every month; never rank it.

value

16.0000

Not a statistic, so no percentile, rank or z is drawn. Its description in core.metric_registry declares it NOT A STATISTIC: a level whose percentile would only track the price.

Last observed 2026-09-30, 1 day before 2026-10-01. The value is carried forward; it is not a reading for 2026-10-01.

40 of 40 with a reading on or before 2026-10-01; 40 carried forward from an earlier day (marked). Each row is that name against its own history — core.metric_context(), one query for all of them — not a rank among them.

Provenance

Source: core.option_strikes
Cadence: daily, XNYS sessions; fetched 19:00 ET, first materialised by the next run
Read by: Page 4's max-pain marker label, so the page reads the expiry instead of re-implementing chain_metrics.monthly_expiry in TS
Point-in-time: RESTATED — values change as corporate actions arrive. Each row's vintage_ts records when it was computed.
Export restriction: INHERITED FROM core.option_strikes, whose uw_option_chains SourceSpec records the basis: UW API Basic is a personal-use tier and the rows carry OPRA-derived NBBO and greeks (DESIGN.md §9.15, ADR-0014). A statistic computed from restricted data is still restricted - a sum is not a licence.
