This project aims to strip the Equity Local Volatility surface and implement the associated PDE pricing method.

End-to-end implied and local volatility surface from live SPY options, with Dupire local vol and an empirical study of the VIX term structure as a predictor of realised volatility.

SVI vol surface, Dupire local volatility (PDE) and Heston calibration, with cross-model repricing on real SPY options

End-to-end implied and local volatility surface from live SPY options, with Dupire local vol and an empirical study of the VIX term structure as a predictor of realised volatility.

Implied and local volatility surface from live SPY options, with Dupire local vol and an empirical study of VIX term structure vs realised vol

Local volatility calibration from implied volatility surfaces using Dupire’s formula, with Monte Carlo pricing of vanilla and exotic options.

Dupire local volatility from a real SPY surface, and what flat-vol pricing costs on a barrier option: 32bp of spot. Live in-browser PDE.
