Early Volatility Models

Algorithm

Early volatility models, initially developed for traditional finance, faced unique challenges adapting to the nascent cryptocurrency markets due to their inherent characteristics like discontinuous price movements and limited historical data. These early approaches often relied on extensions of established models like GARCH, attempting to capture volatility clustering present even in crypto assets, but frequently struggled with accurately predicting extreme events. Parameter calibration proved difficult, requiring modifications to account for the non-normality of returns and the impact of market microstructure effects specific to exchanges. Consequently, initial implementations often served as benchmarks rather than precise predictive tools, highlighting the need for more sophisticated methodologies.
