SMA

Overview of the Simple Moving Average indicator.

A simple moving average (SMA) is an arithmetic average of a set of data points where each data point is added together and then divided by the total number of data points. For example, a 10-period simple moving average finds the closing price of the last 10-periods, sums the 10 closing prices, and divides by 10 to calculate the average closing price of the previous 10 periods. New periods are then added to the calculation and the oldest period is deleted from the calculation.
