Pick a date — the whole workstation rewinds. Same chains the AI is trained on, queryable on every strike.
One archive. Three surfaces — the time-travel UI, the daily analytics, and the backtester.
Four design choices that separate this from a vendor data feed or an academic dataset.
Every strike, every expiry, every Greek — plus the derived metrics on top. 15+ years, queryable.
Pick a date — the whole workstation rewinds. Chains, Greeks, flow tape, and analytics, exactly as they were.
Walls, GEX/DEX, skew, term structure, max pain, put/call, VIX — computed every morning, archived every day.
Any structure, any expiry, simulated against the exact chains you can also browse. Zero drift.
Pay an exchange for ticks, a vendor for analytics, a DBA to stitch them. Or skip all three.
Everything we get asked about the dataset, the analytics, and the backtester.
Skip the data engineering. Delta unlocks historical analytics; Vega adds the full backtesting engine.
