Structural options analytics for the SPX 0DTE market
zdte.ai is a software analytics platform that reads the live SPX options market and reports its structure: dealer positioning, gamma exposure, options flow, and the prevailing volatility regime. The platform continuously estimates these figures from options-chain data through the trading session and presents them as a real-time read of market structure, not as a signal to buy or sell anything.
The platform is deliberately narrow: one index (SPX) and its same-day (0DTE) options complex, covered in depth, rather than shallow coverage across many tickers. The underlying figures - dealer gamma positioning, call and put walls, the zero-gamma level, and options flow - are proprietary estimates built from public options-chain data. They are estimates, not measured facts, and they can be wrong.
Alongside the live platform, zdte.ai publishes free research reconstructing past market episodes from recorded telemetry, and a Field Guide that explains the underlying options-market-structure concepts - gamma exposure, the Greeks, implied volatility, and related terms - in plain language. Both use the same vocabulary as the live product and carry the same estimate-not-fact framing.
