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.

206 of this session’s 225 prints are pending; the other 19 could not be asked at all, for the reason each row gives. Row 2026-09-21 of the chain has not been collected yet — that book is written at 19:00 ET on that session — so the settled open interest these prints produced does not exist anywhere to read. This is the correct state for a session the chain has not reached, not a fault.

These prints settle when 2026-09-21’s book is written, at 19:00 ET on 2026-09-21, which has passed.

Counted in prints, not rated: prints on one contract share one settled OI change, so a rate’s n is the contract count in the table below, and R2 holds it to n_min 20.
