Open interest by strike with the max-pain level marked, per expiry — heuristics over CBOE delayed chains, same strike band as the GEX profile.

History

C open interest, night by night.

Total call and put contracts held on each recorded session — the level the strike profile above is a snapshot of.

One reading per session, captured nightly after the close, 10 Jun → 5 Nov, over CBOE delayed (~15-min) chains, computed across the full listed chain. Gaps are weekends, holidays and sessions a capture missed; any reading can be absent on a session that was captured, and the series is broken rather than drawn through it.
