Historical Volatility Calculation

Historical volatility calculation is the mathematical process of deriving a volatility figure from past price data over a specific look-back period. This typically involves calculating the daily returns, finding the standard deviation of those returns, and annualizing the result to provide a comparable metric.

It provides a baseline for understanding how an asset has behaved in the past, though it does not guarantee future performance. In the crypto domain, choosing the right look-back period is essential, as the market structure changes rapidly.

Traders use this calculation to compare current market conditions against historical norms. It is a foundational quantitative task that informs almost all other volatility analysis.
