Looking for a SpotGamma Alternative?
SpotGamma is one of the most established dealer-positioning services and popularized much of the gamma vocabulary retail traders use today. zdte.ai is a narrower, deeper alternative: real-time SPX and 0DTE market structure specifically, rather than levels across many tickers. Which is better depends on whether you trade one index intraday or many names on longer horizons.
This page is written by zdte.ai. We state each tool's genuine strengths plainly, avoid pricing (it changes — check each provider), and note that all trademarks belong to their owners; zdte.ai is not affiliated with the companies mentioned.
What SpotGamma does well
SpotGamma helped bring dealer-positioning analysis to retail traders and coined or popularized several terms the community now treats as standard. It publishes daily levels across major indices and a broad set of single stocks, runs an active subscriber community, and produces regular written commentary. For a swing trader who wants pre-computed levels across many tickers each morning, it is a strong, proven choice.
Where zdte.ai differs
zdte.ai makes the opposite trade-off: one market, maximum depth. The platform reads SPX and its same-day (0DTE) options complex continuously through the session - a live estimate of dealer positioning, gamma structure, call and put walls, and the prevailing volatility regime, updating as positioning changes intraday rather than as a morning snapshot.
The second difference is the research layer. zdte.ai publishes forensic reconstructions of market episodes built from its own recorded telemetry - month-by-month accounts of how the dealer book formed, held, and unwound - alongside a free educational Field Guide and glossary. The analytics and the education use the same vocabulary, and both are explicit that dealer-positioning figures are proprietary estimates, not measured facts.
Which should you pick?
Pick SpotGamma if you want daily levels across many tickers, an established community, and a broader multi-index product. Pick zdte.ai if your trading day is SPX - especially 0DTE - and you want the structure read continuously intraday rather than once in the morning. Some traders run both: one for breadth, one for depth.

Frequently asked questions
Is zdte.ai a replacement for SpotGamma?
Only if your trading is centered on SPX and 0DTE. SpotGamma covers many tickers; zdte.ai deliberately covers one market in continuous depth. Traders who need multi-ticker levels often keep both.
Do SpotGamma and zdte.ai show the same numbers?
No - and neither is "the" number. Dealer positioning is not directly observable; every provider publishes its own estimate built from open interest and flow under different assumptions. Expect the levels to differ; the structural picture (regime, major walls) often rhymes.
Can I evaluate zdte.ai before subscribing?
The research papers, Field Guide, and glossary are free and public - they are built from the same telemetry and vocabulary as the product, so they are a fair preview of how the platform thinks.
