## Exponential Moving Average Review

The term Exponential Moving Average (EMA) showed up in a number of recent posts.  Those unfamiliar with this term would benefit with a review.  In searching the blog, I thought I defined EMA, but that post was likely lost when I move the blog to a new host provider.  Here is how EMA is calculated.

One first calculates a Smoothing Constant based on the number of days one will be using for the EMA.  For this example, I will use a fast moving 10-Day moving average.

Smoothing Constant = 2/(10 + 1) = 2/11 = 0.18

Now we use the 0.18 Smoothing Constant to calculate a New Exponential Moving Average.

New Exponential Moving Average = Smoothing Constant (Today’s Close – Yesterday’s EMA) + Yesterday’s EMA.

Assume Yesterday’s EMA = 50 and Today’s Close = 51.  We then have a new 10-Day EMA as calculated.

New EMA = 0.18 * (51 – 50) + 50 = 0.18 * (1) + 50 = 0.18 + 50 = 50.18 or 50.2.

Take another example, where we use a much slower EMA, such as a 195-Day EMA.  First, we need to calculate a new Smoothing Constant.

Smoothing Constant = 2/(195 + 1) = 2/196 = 0.01.

New EMA = 0.01*(51 – 50) + 50 = 0.01 * 1 + 50 = 50.01

Note how little change is taking place with the 195-Day EMA.
