How many data points should be used to calculate each value of the moving average?
An interval is how many prior points you want Excel to use to calculate the moving average. For example, “5” would use the previous 5 data points to calculate the average for each subsequent point. The lower the interval, the closer your moving average is to your original data set.
What is 7-day moving average?
For a 7-day moving average, it takes the last 7 days, adds them up, and divides it by 7. For a 14-day average, it will take the past 14 days. So, for example, we have data on COVID starting March 12. For the 7-day moving average, it needs 7 days of COVID cases: that is the reason it only starts on March 19.

How to calculate the simple moving average of a security?
The formula for calculating the simple moving average of a security is as follows: The exponential moving average is a type of moving average that gives more weight to recent prices in an attempt to make it more responsive to new information. To calculate an EMA, you must first compute the simple moving average (SMA) over a particular time period.
How to calculate the simple moving average ( EMA )?
To calculate an EMA, you must first compute the simple moving average (SMA) over a particular time period. Next, you must calculate the multiplier for weighting the EMA (the smoothing), which typically follows the formula: [2 ÷ (selected time period + 1)]. So, for a 20-day moving average, the multiplier would be [2/(20+1)]= 0.0952.
