For premium sellers & call writers

Sell premium when volatility is genuinely rich, and stand down when it isn't.

VRP z-scores and percentiles tell you when implied vol is statistically rich versus realized; IV rank and term structure time the entry; max pain frames the strikes.

The problem

What the usual options data leaves you fighting

A high IV rank doesn't mean the premium is actually rich versus realized vol.

You sell into earnings and get run over by an IV move you didn't size.

Pins and walls drift your tested short strikes after you're on the trade.

What FlashAlpha gives you

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.

Questions, answered

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.

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.

Which plan has VRP analytics?

Full volatility and IV-rank data is Growth; the VRP dashboard (z-score, percentile, directional VRP, regime) and historical VRP percentiles are Alpha.

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.

Recommended plan

Growth $239/mo

billed annually ($2,868/yr)

Growth covers full vol and IV-rank data; Alpha adds VRP analytics so you sell premium only when it is statistically rich.
