Simple Moving Average Explained in Fewer Steps

Moving averages act as technical indicators that demonstrate the average price movement over a particular period. they're typically wont to facilitate highlight trends, spot trend reversals, and supply trade signals.

What is a Simple Moving Average (SMA)?

A simple moving average (SMA) computes the average of a particular range of prices, typically closing prices, by the number of periods in this range.

A simple moving average could be a technical indicator that supports deciding if an asset worth can continue or if it'll reverse a bull or bear trend.

Simple Moving Average Method

  • A simple moving average (SMA) is an arithmetic moving average computed by adding recent prices and then dividing that total by the number of periods within the calculation average.
  • A simple moving average is versatile for the explanation that it may be calculated for various numbers of your periods. this can be an exercise by adding the price security for a variety of your periods and then dividing this total by the number of your periods, which supplies the average price of the security over the period.
  • A simple moving average is easy volatility and causes it easier to look at the value trend of a security. Suppose the SMA  points up, this implies that the security's worth or price is increasing. If it's informed down, it implies that the security's worth is decreasing. The longer the time frame for the moving average, the smoother the easy moving average. A shorter-term moving average is additional volatile, however, its reading is nearer to the supply knowledge.

Simple Moving Average Calculation

The simple moving average (SMA) calculates a mean of the last n prices, wherever PX represents the price during a time, and n represents the number of periods. The average "moves" as a result of you're not using all the data, solely recent periods:

SMA Formulae


  • For example, a four-period SMA with prices of 1..2740, 1.2741, 1.2742, and 1.2741 provides a moving average of one.2741 mistreatment the calculation (1.2740 + 1.2741 + 1.2742 + 1.2741) / 4 = 1.2741.
  • The advantage of an SMA is that you simply grasp what you're obtaining. The SMA price equals the average price for the number of periods within the SMA calculation.
  • Traders usually used, 20, 50, 100, and 200 periods for an SMA. For example, if employing a 100-period SMA, the worth of the SMA on the chart is the average price over the last a hundred periods or price bars.


  • Some charts include the SMA, together with an exponential moving average (EMA). They'll even have a weighted moving average (WMA) on a one-minute stock chart. Due to their completely different calculations, the symptoms seem at completely different price levels on the chart.
  • It is not clear whether importance should be placed on the foremost recent days within the period or more distant data. Several traders believe that new data can higher replicate this trend the price security is moving with.
  • At the same time, different traders feel that privileging specific dates over others can bias the trend. Therefore, the SMA might count too heavily on out-of-date data since it treats the tenth or two hundredth day's impact identical because the initial or second day's.



Similarly, the SMA depends utterly on historical data. Many folks (including economists) believe that markets are efficient that is, that current market costs already replicate all accessible info. If markets are so economical, using historical data ought to tell us nothing concerning the long-run direction of asset costs.

What is the distinction between a Simple Moving Average and an Exponential Moving Average?

  • While a simple moving average provides equal weight to every one of the values inside a period, an exponential moving average places a larger weight on recent costs.
  • Exponential moving averages are usually seen as an additional timely indicator of a price trend, and since this, several traders like to make use of this over a simple moving average.
  • Usually, short-term exponential moving averages include the 12-day and 26-day. The 50-day and 200-day exponential moving averages are accustomed to indicating long-term trends.
