![]() ![]() Next, you must calculate the multiplier for smoothing (weighting) the EMA, which typically follows this formula. For example, a 50-day SMA would be just the sum of the closing prices for the past 50 trading days, divided by 50. ![]() It is simply the sum of each day’s closing prices during a time period, divided by the number of observations for that period. The calculation for the SMA is straightforward. On the 51st day, you can then use that SMA as the first EMA for yesterday. If you want to use 50 days as your time period, you must first wait until the 50th trading day to calculate the SMA. The EMA is used as a trend-following or mean-reversion indicator.Ĭalculating the EMA is slightly more complicated than calculating the SMA. The exponential moving average (EMA) is a type of moving average calculated by applying an exponential function to the sum of the previous values, each multiplied by a weighting factor. It uses the number of periods specified in the moving average. *The smoothing constant applies appropriate weight to the most recent price. Smoothing = Exponential smoothing constant The Formula for EMAĮMA_yesterday = Previous periods EMA (A SMA is used for the first period’s calculations) The exponential moving average is used to smooth the movements of the price series, and it reacts more significantly to those price changes. The EMA is also referred to as an exponentially weighted moving average or an exponentially smoothed moving average. It is also considered a lagging indicator, meaning it gives an indication of past prices that is less relevant to current conditions.Īn exponential moving average reacts to recent price changes more than a simple moving average, which places equal weight on all observations in the period. Murphy, who called it the “Wilder Moving Average.” The EMA is a smoother, more flexible type of moving average, which “rolls off” older price data more quickly than a simple moving average. It was invented by Welles Wilder in 1978 and popularized by the technical analyst John J. The exponential moving average (EMA) is one of the most popular technical indicators used to help spot trends in financial markets. What Is an Exponential Moving Average (EMA)? ![]()
