Comparing Strike- and Delta-Based Option Volatility Skew
Summary
The document introduces two historical option volatility views for a selected expiration. The strike view plots implied volatility curves over time against strike, while the delta view plots them against delta. These views let analysts examine how the volatility smile changes over time in different coordinate systems.
The stated advantage of delta-based comparison is that it avoids distortions caused by movements in the underlying price, which can make fixed-strike curves harder to compare through time. The page also mentions combining these charts with volatility footprint charts for a broader view. It gives no sample analysis, performance evidence, or detailed methodology, so it describes a data visualization feature rather than a trading strategy or validated signal. The examples and access directions are specific to the provider’s options data interface.
Key ideas
- The strike view displays implied volatility curves over time across strike prices.
- The delta view displays the same curves across delta values for a selected expiration.
- Delta-based comparisons reduce distortions from changes in the underlying price.
- Volatility curves can be considered alongside volatility footprint charts for broader analysis.
