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.

Official CBOE Data*

Direct from the exchange — not modeled, not estimated.

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 600+ equities using data consolidated across every US options exchange.
