How to read these numbers

This edition reads TradingFlow's Daily Market Recap for October 27, 2026, captured on October 30 (New York time). Two runs a minute apart printed the same figures. It is a completed-session report, not a trade recommendation.

Two clocks apply. Premium, sentiment, and prints describe the session tape; GEX and IV are the recap's T+1 / prior-close snapshots, not a live intraday gamma map. Neutral premium supplies no direction, and call share is option type, not bullish sentiment. Net DEI is an unsigned magnitude relative to typical activity; Net DEX is a separate signed classification, and a +0M reading rounds to zero. GEX is modeled chain structure under TradingFlow's dealer-sign convention, not observed dealer inventory, a support level, or the next session's direction. Ticket tags do not prove who bought or sold or whether a position opened, and intraday_pct is a first-to-last underlying-price proxy from the option tape, not a verified daily return.
