Replay any date

Bottom linePick any stock and any date — the page replays exactly what was publicly knowable on that date, through the same audited API a client uses. Proof of zero look-ahead you can drive yourself; a demonstration, not a recommendation.

Replay any date. The worked one-pager (Replay the Tape) demonstrates zero look-ahead on two historical cases; this page is the live counterpart — every query below goes through the entitled /v1 API (auth, metering, provenance stamps and all) and renders exactly what was publicly knowable on the date you pick. Nothing on this page is authored by the page: values, absences and errors are the API's own, and each panel carries the curl that reproduces it. Same date, same answer. Descriptive record only — nothing here is a recommendation or a performance claim.

Two-tier knowable clock (D104): EVENT = the period's real public clock (concall held / transcript published — the later of the two); MODELED = no captured clock, so the point counts as knowable only once its label month completes. Result filings are never used as a clock for call-derived content (filings usually precede the call — the leak direction).

worked examples: ICICIPRULI · 2019-01-25 (real call clock — the Feb-labeled point, knowable Jan-22) same name, one day before the call (the prior point serves — no leak) TANLA · 2020-06-30 RELIANCE · 2026-07-09 (recent — the event bus as it stood)
