Realized Variance Estimation

Calculation

Realized variance estimation, within cryptocurrency and derivatives markets, represents a backward-looking measure of price dispersion, computed from observed transaction data. It differs from implied variance, derived from option prices, by focusing on historical price movements rather than market expectations. This calculation typically involves summing the squared returns of an asset over a defined period, providing a quantifiable assessment of past volatility. Accurate realized variance estimation is crucial for calibrating option pricing models and evaluating trading strategies, particularly those reliant on volatility arbitrage.
