## Heston Model

The Heston model is a popular stochastic volatility model that assumes the variance of an asset follows a mean-reverting process. It allows for the correlation between the asset price and its volatility, which is crucial for modeling the leverage effect observed in equity and crypto markets.

By providing a closed-form solution for European option prices, it remains a standard tool for traders needing to calibrate models to market data. The model's ability to capture the volatility skew makes it more robust than simpler models that ignore the relationship between price drops and volatility spikes.

It represents a significant step forward in aligning theoretical pricing with the realities of market risk and volatility dynamics.
