Moving Average

A technical analysis indicator that smooths price data by averaging over a rolling window. Common variants: simple moving average (SMA — arithmetic mean), exponential moving average (EMA — weights recent prices higher). Commonly-cited crypto MAs: 20-day, 50-day, 200-day. Crossovers (e.g., 50-day above 200-day = 'golden cross') are traditional trend signals; empirical predictive value is contested.
