Let’s use these formulas on an example to calculate exponential moving average in Excel. There a few ways that traders can trade with the exponential moving average. If you want to calculate the SMA of the last 20 days, we simply sum up the values of the last 20 closing prices and divide by 20. In this article, we are going to discuss the exponential moving average , how it is calculated and how you can use it to make trading decisions.

## Exponential Moving Average Ema Vs Simple Moving Average Sma

You should notice how the EMA uses the previous value of the EMA in its calculation. This means the EMA includes all the price data within its current value. The newest price data has the most impact on the Moving Average and the oldest prices data has only a minimal impact. Use the EMA to determine trend direction, and trade in that direction. When the EMA rises, you may want to consider buying when prices dip near or just below the EMA.

### Is SMA same as Ma?

A moving average (MA) is a stock indicator that is commonly used in technical analysis. … A simple moving average (SMA) is a calculation that takes the arithmetic mean of a given set of prices over the specific number of days in the past; for example, over the previous 15, 30, 100, or 200 days.

## Cumulative Moving Average

The calculation for the SMA is the same as computing an average or mean.
