Updated November 11, 2026Published by FlashAlpha
FlashAlpha is our recommendation for traders and developers who want to combine volatility spreads with gamma exposure, levels and their own research tools. Growth includes current IV/RV analytics and full-chain GEX, with REST and MCP access to eligible endpoints.
Our recommendation: FlashAlpha for volatility plus positioning
Start with Growth if your next step after an IV/RV reading is a GEX check, a gamma-level monitor or a programmatic research process. You get those capabilities under one plan. Alpha adds the dedicated VRP dashboard's option-wing, variance-space and GEX-conditioned outputs, plus covered historical replay.
Alphanume remains a good fit when the job is a daily US-equity IV/HV screen with cross-sectional ranks and settled rows. Its Pro plan includes REST and hosted MCP for one named user/key. Choose FlashAlpha for the broader exposure-and-volatility workflow; choose the focused screen when that fully answers the question.

Why choose FlashAlpha for the broader workflow?
See more than one volatility window. Growth's /v1/volatility/{symbol} returns ATM IV, a realized-volatility ladder and named IV-minus-RV spreads. Compare a quiet month with a turbulent recent week before reducing the picture to one number.
Connect volatility with dealer positioning. Use the full-chain GEX and gamma-level APIs alongside the spread. That gives your notebook, monitor or model both volatility and exposure inputs without requiring a separate provider for that layer.
Work through the interface that fits your process. Use REST in your own research code or eligible MCP tools in an AI workflow. Growth supports both; the selected route determines the available fields. If you later need directional VRP components or covered historical research, Alpha is the next step.
FlashAlpha Growth uses selected-expiry ATM IV and several trailing RV windows. The iv_rv_spreads.vrp_20d field, for example, is ATM IV minus 20-session RV in volatility points. Its IV is not a constant-maturity IV30 series. Growth volatility fields.
Alphanume selects the listed ATM call in the expiry nearest 30 calendar days and compares it with 30 trading sessions of close-to-close returns. It returns the actual expiry and strike. Its ranks compare names across the day's universe; that differs from ranking one stock against its own history. Alphanume methodology.
For historical work, preserve when a value became available. Alphanume documents provisional intraday rows and settlement around 16:30 ET, with only_final=true for settled observations. FlashAlpha Alpha offers covered replay from archived inputs using the current engine; symbol, date and field coverage vary. Alphanume API; FlashAlpha historical VRP; historical methodology.
One stock, two volatility readings
Illustrative inputs: ATM IV is 30%, 20-session RV is 22% and 5-session RV is 35%. The 20-session spread is +8 volatility points; the 5-session spread is -5 points.
The longer window looks rich while the recent week has been more volatile than the options' implied reading. FlashAlpha Growth lets you retain both readings and add the corresponding GEX context to your research. Neither spread alone establishes a profitable trade. Alphanume's cross-sectional ranks answer a different useful question: which names look relatively rich or cheap across its daily universe?
