InstitutionalEdge. Retail Access.
Officially licensed CBOE data provider with 1-minute SPX and VIX data. Officially licensed CBOE Global Indices Feed (CGIF). SPX and VIX intraday option pricing. See where market makers are actually positioned — not where someone thinks they might be.
Why This Is Different
Other tools guess.
We don't.
Most retail GEX tools model dealer positioning from public open interest or infer it from order flow. We use official CBOE data from the C1 exchange — where every SPX and VIX option actually trades.
