ExponentialMovingAverage

The Exponential Moving Average (Ema) is a widely-used technical indicator that gives more weight to recent price data, making it more responsive to new information compared to a Simple Moving Average (SMA). The Ema decreases the lag by applying more weight to recent prices relative to older prices. The Ema can provide key market signals. A common interpretation is that when the Ema crosses above the price, it's a buy signal, and when it crosses below, it's a sell signal. The Ema is calculated with the formula: EMA_i = EMA_i-1 + K * (Price - EMA_i-1) where K is the smoothing factor calculated by 2 / (Period + 1). This formula allows the Ema to be continuously updated as new price data becomes available.
