Introduction

A simple moving average is calculated by adding the closing price of the security for a number of time periods and then dividing this total by the number of time periods. Short-term averages respond quickly, while long-term averages react slowly to changes in the price.

Note:
Mostly Moving Averages can be calculated on the base of closing price of security, but we can calculate it using Open, High, or Low price as well.

Formula

SMA = Sum of closing price of security over period / Number of period
