gex.live compared
Five tools that sell dealer-gamma positioning, read off their own public pages on 2026-08-25. One row is marked amber against us, and it is there on purpose — the honest version of a comparison table is the only kind worth publishing.

The row we lose, and why it is in the table
OptionsDepth reads participant-tagged data straight from the exchange: their dealer side is stated by Cboe, not guessed. Ours is inferred — we sign each print by which side of the spread the aggressor hit. That inference is good in some regimes and poor in others, and rather than describe it with an adjective we publish the measurements: see which gamma measure sees anything and which book is the zero-gamma flip. If exchange-tagged truth per strike is the thing you are buying, they have it and we do not.
What we have instead is the thing that makes an inferred number checkable: 1,088+ finished sessions, free, no account. Every level this site has ever printed sits in that archive next to what price actually did. Their history window is 30 days unless you buy the data separately. So the two products answer different questions — theirs is "what is the dealer's tagged position right now", ours is "does this level do anything, measured over four years, and can I test my own rule against it".
Where each of the others is genuinely stronger
- OptionsDepth — exchange-tagged participant data, and Charm/Vanna projections as heatmaps rather than single numbers.
- TanukiTrade — breadth (250+ symbols) and delivery where traders already sit: TradingView indicators and Discord bots.
- GammaEdge — education. A structured course, a daily and a weekly newsletter, and by far the deepest library of explanatory writing in this niche.
- OPEX Trader — surface area: 390+ analytics tabs, eleven asset modes and a desktop app that runs its models locally.
Where this one is
- The archive is the product's proof, and it is free. 1,088+ sessions, no account, permanently. Nothing here asks you to trust a number you cannot check.
- LAB answers "did this actually work". Describe a rule in plain words, get an out-of-sample verdict on the whole archive — including "no edge", which is what most ideas honestly return.
- An MCP server that works today. Point Claude or Cursor at
mcp.gex.live/mcp; the session tools are free. - No signals, ever. Measurements and verdicts, never an instruction to buy.
- One symbol, done properly. SPX, rebuilt from the tape second by second.
