One reading per session, captured nightly after the close, 10 Jun → 14 Sep, 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.
