What customers say
Trusted by systematic traders & quant researchers
“FlashAlpha is essential infrastructure. It’s the only source for aggregate charm and vanna exposure, and that data feeds 4 of our top 5 predictive features.”
J
Joel
Quant researcher
“The best options analytics service I’ve used. I code my own tools and dashboards using their API, and the price-to-benefit ratio is through the roof.”

Verified review
“First day live: 3 trades, 3 winners. More importantly, it blocked 30+ bad signals, including 5 institutional put trades that would have lost money.”
A
Alonso
Independent trader
“Integrating FlashAlpha into our systematic 0DTE SPX iron condor regime scoring. GEX regime, dealer hedging estimates, and vol surface are exactly what we needed.”

| Data freshness?Every endpoint is served from an in-memory snapshot. Your plan's window is how stale that snapshot can get before we refresh upstream. Cache is shared: when anyone triggers a refresh, everyone benefits. A single-flight guard collapses concurrent requests into one upstream fetch - no thundering herd. | 15 min | 15s | 15s | No cache |
