These frameworks treat the instantaneous volatility of the crypto asset as an unobserved random variable following its own stochastic process. This approach moves beyond the constant volatility assumption of simpler methods. Calibration to market data is an intensive computational task.
Volatility
The core advantage lies in capturing the empirically observed phenomenon that volatility clusters and changes over time, especially in high-energy crypto markets. This captures the time-varying nature of risk. Accurate estimation of the volatility process parameters is key.
Process
Implementation often involves numerical techniques like finite difference methods or simulation to derive option prices consistent with the assumed volatility dynamics. Understanding the chosen process dictates the model’s predictive power for derivative pricing.
