Flow → OI

A session’s notable prints on tracked tickers, each joined to the open interest its contract actually settled the next morning, and stamped opened, closed, rolled, unresolved or pending. The question a print raises is answered by OI, never by the print itself.

The floor picks which prints are listed. It cannot move a verdict: a contract is judged on every alert it drew, whatever their premium.

Showing 2026-09-17 — the newest session with both halves of the question: its alerts, and the chain book that settles them. The newest book stored is 2026-09-18’s, and a book is the settlement of the session before it.

Alerts are stored through 2026-09-18, 1 open session newer than this one — not judgeable yet, and still one click away.

The next chain book, 2026-09-21’s at 19:00 ET on 2026-09-21, settles 2026-09-18’s prints.
