Options chain activity
A contract-level workspace for dated chain observations. Volume and open interest describe activity, not who traded or why.
Source: No permitted chain publication · snapshot as of unavailable. DTE is measured from the current market date. OI observation date is separate from quote time.
Stored Greek summaries · unweighted, per share
Not signed positions or portfolio exposure. Theta is annualized; vega is per one percentage-point IV change. Stored Greeks may contain model fallback; origin is not separately recorded.
Earnings presets use the stored report date; “avoid” excludes unknown dates. Verify schedule revisions separately. Missing sort values always remain last.

Research summaries do not contain a full chain. Raw provider storage is not public-display approval; no contracts have been invented from strategy legs.

- Stored chain observations, not live tape, prints, sweeps or institutional intent.
- Premium is midpoint × 100 under a standard-contract assumption; not executed premium or dollar flow.
- Greeks are stored normalized values: theta annualized per share, vega per 1 volatility point. Provider/model origin is not separately recorded.
- OI date is unavailable unless independently supplied. Missing values are never zero.
- No reviewed public-display chain manifest available. Raw provider cache and unreviewed chains are not exposed.
