By what the book did:the session screener (regime, percentile, crossings, move, event)
Each page summarises one trading day of SPX dealer positioning and opens the full minute-by-minute replay in the terminal. All of it is free — the only thing sold on this site is the live stream while the market trades. The session that has not finished yet is on /now, fifteen minutes behind the tape. New to the terms? Start with what GEX is, then the zero-gamma flip, call resistance and put support, and vanna and charm. Put to all of these sessions at once: the research pages — how often the levels hold, how far price travels before the close.
