What FlashAlpha offers
Quantify the edge before you sell: VRP measures implied minus realized, z-scored and percentile-ranked so you know when premium is statistically rich, not just when IV looks high.

Frequently Asked Questions
Everything you need to know before using the API.
Q
What is VRP and why z-score it?
Volatility risk premium is implied vol minus realized vol, the edge a seller harvests. Z-scoring and percentile-ranking it against history tells you whether today's premium is actually rich, not just high.
Q
IV rank vs IV percentile, which should I use?
IV rank scales today's IV between its 52-week high and low; IV percentile is the share of days below today. Percentile is more robust to outliers; the guide above covers when each matters.
Q
Which plan has VRP analytics?
The full volatility profile (IV-RV spreads, skew, term structure) is Growth; the VRP dashboard (z-score, percentile, directional VRP, regime) and historical VRP percentiles are Alpha.
Q
Does VRP work on single names or just the index?
Both, and single-name VRP behaves very differently around earnings than index VRP, which is exactly when sizing matters most.
Growth
billed annually ($2,868/yr)
The premium seller's toolkit: full volatility profile, term structure, expected move and the earnings calendar - sell rich vol, stand down on cheap vol.
- IV-RV spread, live - sell rich vol, stand down on cheap vol
- Full volatility profile - term structure and realized-vs-implied context
- Earnings calendar + expected move - never short a jump you did not price
- VIX regime state - the macro gate on every entry
When Alpha instead: VRP z-scores and percentiles tell you the premium is statistically rich - not just high - and the no-lookahead VRP history lets you backtest the rule.
