Why This Is Different
The real book on SPX.
The full map on everything else.
On SPX and VIX we use official CBOE data from the C1 exchange, where every SPX and VIX option trades, so you see which side market makers actually hold. Across 5,000+ other tickers we read open interest and volume consolidated from every US options exchange: where positioning is concentrated and how it shifts through the day. Every view is labeled, so you always know which one you're reading.
Official CBOE Data*
Direct from the exchange, signed by participant type.
True Dealer Positioning*
C1 is the only exchange where SPX & VIX options trade. Our market maker flow comes straight from the source.
Updated Every Minute*
1-minute positioning data throughout the trading day. Per-contract pricing shows how every call and put evolves in real time.
* Official CBOE / C1 data and dealer positioning apply to quantedGamma Classic & Ultra (licensed SPX & VIX). quantedTrader brings gamma, net delta and premium flow for SPY, QQQ, IWM, DIA and 5,000+ equities using data consolidated across every US options exchange.
