Definition. Annualized Realized Volatility (All) is the standard deviation of BTC returns from the mean return of the market, measured over rolling windows of 1 week, 2 weeks, 1 month, 3 months, 6 months, and 1 year, each annualized.

Technical. Computed on log returns over a fixed time horizon or a rolling window to obtain a time-dependent observable. Realized volatility is calculated from daily returns and multiplied by a factor of sqrt(365) to yield the annualized daily realized volatility. Whereas implied volatility reflects the market's assessment of future volatility, realized volatility measures what happened in the past.

Interpretation. High values indicate a phase of high risk in the market.

This is the Point-in-Time (PiT) variant of Realized Volatility (All). PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
