# OptionsTape.Trade LLM Reference OptionsTape.Trade analyzes institutional options flow, detected significant prints, exchange complex packages, implied-volatility context, open-interest evidence, and unusual-flow conditions. Definitions: - Detected-card flow: high-signal options prints captured and classified by sg_tas. This is not full-market volume. - Full-market volume: broader contract volume snapshot when explicitly sourced and labeled. - Trade IV: implied volatility solved from the print price when available and sanity checked. - Feed IV: implied volatility carried by the upstream options data feed. - Mid IV: implied volatility solved from the NBBO midpoint. - Surface IV: sg-risk-engine fair-volatility estimate for the contract. - Vol Edge: volatility difference in basis points versus the model surface. - Package intent: estimated opening, closing, rolling, covering, overwrite, or adjustment logic inferred from legs, OI, expiry, and size.
