Market History

How this archive is built

Every US trading day gets a record: the session, the scheduled releases with their readings when the data feed carries them, the headlines the site curated through the day, and the AI market summaries published as the session unfolded — pre-open, midday and close — with editor corrections disclosed.

Records are captured when the session ends and finalized the next morning against the official bars. A day-in-review narrative is then generated from the record alone and gated so that every figure it uses appears in the record; if it cannot pass that gate, the page publishes the record without one. Corrections go through an audited path and are listed on each page. The underlying JSON is public and linked from every page.
