Using IV Skew to Structure Options Trades
The 25-delta risk reversal - IV of the 25-delta put minus IV of the 25-delta call - is the gold-standard way to quantify skew. Matching options by delta (rather than by strike) holds moneyness constant on both wings, so the difference isolates pure put-vs-call bid. Positive numbers mean the market is paying up for crash protection; negative numbers mean calls are more expensive (rare outside of buyouts/squeezes).
Credit Spreads
High put skew = expensive OTM puts. Sell OTM put spreads to collect elevated premium while defining your max loss.
Iron Condors
Elevated ATM IV + steep skew: sell OTM puts and calls simultaneously, sizing the put wing wider to match the skew-adjusted premium.
Risk Reversals
Sell the expensive OTM put and buy the cheaper OTM call for a bullish position near zero cost- skew is what makes this trade asymmetric.
Why IV Rank & Percentile Aren't Shown
IVR compares today's IV to the absolute 52-week high/low. IVP counts the % of days in the past year where IV was lower than today. Both require a time series of ~252 daily IV observations per ticker - data only available via authenticated historical chain queries.
With a CuteMarkets Developer or Expert API key you can query historical snapshot IV for any ticker and date, making IVR/IVP trivial to compute in your own pipeline.
