EMA

Exponential Moving Average — an exponential moving average. Exponential Moving Average (EMA) assigns exponentially decreasing weight to historical data, making it more sensitive to recent prices compared to SMA. Widely used as a trend filter (200 EMA), a dynamic support/resistance level, and a component of other indicators (MACD, Bollinger Bands).

Formula:

k = 2 / (period + 1)
EMA = Close * k + EMA_prev * (1 - k)
