What is Moving Average?

Moving averages are technical analysis indicators that reduce “noise” from erratic price swings to help smooth out the market activity. It is created by taking the average of a security’s price over a set period. The most common periods used are 20, 50, and 200 days. 

Investors use moving averages to identify trends and make investment decisions. An uptrend is indicated by a rising moving average, whilst a downtrend is shown by a decreasing moving average for the securities. Moving averages can also be used to identify support and resistance levels. 

Although moving averages are a prevalent technical analysis tool, it is best to employ more than one indication when making financial decisions.

Moving Average Meaning

A stock indicator known as a moving average (MA) is frequently used during technical analysis to assist in smoothing out price data by generating a continuously updated average price. An uptrend is indicated by a rising moving average, while a downtrend is shown by a dropping moving average for the securities.

The impact of random, short-term changes on the price of a particular stock over a given period is reduced by using the moving average calculation.

Types of Moving Averages

There are different moving averages, including simple, exponential, and weighted. Each has its advantages and disadvantages. 

d Simple moving averages

They are the most common type of moving average. They are easy to calculate and interpret but are subject to lag because they only use past prices. Traders use the SMA indicator to indicate when to join or quit a market. An SMA is backward-looking based on historical price data for a specific period. It may be calculated for various price indices, including high, low, opening, and closure.

Simple Moving Average is calculated using the following formula:

SMA = (A1 + A2 +……………An) / n

Here, the average in period n is A, and n is the total number of periods.

d Exponential moving averages

They give more weight to recent prices, which makes them more responsive to recent changes in the market. This makes the EMA more responsive to recent price changes than a simple moving average.

EMA’s are used in technical analysis to create buy and sell signals and identify trends. They are also used in some types of trading systems.

There are a few different ways to calculate an exponential moving average, but the most common is to take a percentage of the previous EMA and add it to the current price. This weighting gives more importance to the most recent data while still giving some importance to older data.

EMA’s can be used at any time but are most commonly used on daily or weekly charts.

d Weighted moving averages

A weighted moving average is a moving average that puts more weight on recent data points and less on older data points. This makes it a more responsive indicator than a simple moving average, which gives equal weight to all data points.

Weighted moving averages are commonly used in the stock market to smooth out price data and make it easier to identify trends. They can also be used to forecast future prices, although this is more difficult to do accurately.

There are two main types of weighted moving averages: exponential and linear. Exponential moving averages give more weight to recent data points, while linear moving averages give equal weight to all data points.

Weighted moving averages are a useful tool for stock market investors. Still, they should be used with other technical indicators to get the most accurate picture of what is happening in the market.


Experts can assess resistance and support using the moving average by analyzing price changes for an asset. A moving average depicts the security’s past price movement or action. Analysts or investors then use the information to forecast the course of the asset price. It is referred to as a lagging indicator because it lags behind the underlying asset’s price movement to provide a signal or reveal the trend’s direction.
