EMA (Exponential Moving Average)

The EMA (Exponential Moving Average) is another type of moving average that gives more weight to the most recent price data. This makes it more responsive to recent price changes than the Simple Moving Average (SMA). EMAs are commonly used to identify the direction of a trend and to generate buy and sell signals.
