How to Calculate an Exponential Moving Average in R
Nov 11, 2023 · An exponential moving average (EMA) is a type of moving average that gives more weight to recent observations. In R, the EMA can be calculated using the ‘SMA’ function from the ‘TTR’ package. The function requires the data, the window size, and the type of averaging (simple or exponential) as inputs.

For EMA, wilder=FALSE (the default) uses an exponential smoothing ratio of 2/(n+1), while wilder=TRUE uses Welles Wilder's exponential smoothing ratio of 1/n. The EMA result is initialized with the n-period sample average at period n. The exponential decay is applied from that point forward.

Fast R implementation of an Exponentially Weighted Moving Average? Here is a custom function. ema_2 <- function (k, width) { ratio <- 2/(width + 1) c(stats::filter(k * ratio, 1 - ratio, "convolution", init = k[1])) } The ideal solution should take at most twice the computation time as taken by EMA function of TTR library.
