Historical Volatility Index

A historical volatility index is a numerical representation of the annualized standard deviation of an asset's past price returns over a defined period. It serves as a benchmark for measuring the intensity of market fluctuations and provides a reference point for comparing current market conditions to historical norms.

Traders and investors use this index to assess the risk environment and to calibrate their trading strategies. A rising index indicates increasing market turbulence, while a falling index suggests a period of relative calm.

By monitoring this index, market participants can better understand the prevailing market regime and adjust their exposure accordingly. It is a critical data point for fundamental analysis and risk assessment in both traditional and digital asset markets.
