## Realized Volatility Measurement

Realized volatility measurement is the process of calculating the actual historical price fluctuations of a financial asset over a specific time period. Unlike implied volatility, which is forward-looking and derived from options prices, realized volatility is backward-looking and based on observed transaction data.

In cryptocurrency and derivatives markets, it is typically calculated by taking the standard deviation of the asset's log returns over a set number of intervals. This metric provides traders and risk managers with a concrete view of how much an asset has actually moved, rather than how much the market expects it to move.

It is essential for calibrating risk models, setting margin requirements, and evaluating the performance of trading strategies. High realized volatility indicates significant price dispersion, while low realized volatility suggests price stability.

Traders use this measurement to assess whether options are expensive or cheap relative to historical performance. By analyzing these fluctuations, participants can better understand the underlying market microstructure and liquidity dynamics.

It serves as a foundational input for delta-neutral hedging and various quantitative strategies. Ultimately, it quantifies the noise and directional shifts inherent in an asset's price history.
