SPX dealer gamma, rebuilt every second from the tape
Rebuilds the SPX dealer options book from the live tape: zero-gamma flip, call and put walls, hold band, and DEX/VEX/vanna/charm per strike. Positions are signed from trades, not the call/put convention. Volume, open interest and measured flow sit side by side, so you can see where they disagree. 1,000+ finished sessions are free forever, no account. A backtesting Lab and an MCP server come with it. No buy/sell signals.

Hi Product Hunt 👋
I built gex.live because every dealer-gamma tool I could find asks you to take its numbers on faith. Two things are different here.
First, positions are signed from the actual tape rather than assumed from the call/put convention, and where that method is uncertain, the site says so instead of rounding it into confidence.
Second, every finished session is free forever, no account 1,000+ of them. You can check today's levels against a thousand days of history before paying for anything. The subscription only buys today's live stream.
There are no buy/sell signals and there never will be. It is a measurement instrument.
There's also an MCP server, so you can ask your AI assistant about SPX dealer positioning directly. Happy to answer anything about the method especially the parts that don't work yet.
