Simple Moving Average

A simple moving average is made by adding the closer together, For however many days you want to be in the moving average, and then dividing by that number of days. So for a 5 day moving average you would add up the last 5 closes, and then divide by 5 to give you today’s moving average number.
Each day moving average number is plotted and forms a moving average line on the chart. Other Moving Averages, There are also other ways to calculate a moving average by giving the most recent close more importance and those are called exponential and weighted moving averages, which we will look at later, but for now let’s just stick with simple moving averages.
