EWMA Volatility Calculation

Methodology

Exponentially Weighted Moving Average volatility provides a dynamic framework for estimating current market variance by assigning progressively lower weights to older price observations. This recursive approach ensures that recent price actions exert a more significant influence on the forecast than dated data points, which proves essential in the fast-paced environment of cryptocurrency markets. Traders utilize this model to capture shifting risk regimes without the structural lag inherent in simple moving averages.
