Historical Volatility Realization

Historical Volatility Realization is the measurement of the actual price fluctuations of an asset over a specific past time frame. It is calculated by taking the standard deviation of the logarithmic returns of the asset over that period.

This metric provides a baseline to compare against the forward-looking implied volatility derived from option prices. In cryptocurrency, realized volatility is often significantly higher than in traditional asset classes, reflecting the asset's nascent nature and high sensitivity to liquidity flows.

Traders use this data to calibrate their models and validate their assumptions about market risk. If the realized volatility is consistently lower than the implied volatility, it suggests that the market is overpricing risk.

Conversely, if realized volatility exceeds implied, it indicates that options were historically underpriced. This comparison is vital for backtesting strategies and assessing the accuracy of pricing models.

It serves as a grounded reality check against speculative market expectations.
