What Are Volatility Indicators on MT4?

Using common volatility indicators on MT4 might help you make sense of the commotion occurring on forex charts. In forex trading, volatility has two sides

On one side, volatility allows forex traders to benefit, mainly when trading short-term. However, opposing this, increasing volatility reduces the predictability of market moves.

As a logical investor, you don't want to be caught off guard by market volatility that changes prices in unexpected directions while attempting to execute deals.

We will show a basic volatility calculation and four indicators that have been shown to assist traders in identifying volatility while considering trade possibilities.

How Volatility Is Calculated

It is beneficial to understand how volatility works when considering whether to begin a new trade.

  • Using the standard deviation of the variance of a currency pair's value over a period of time is one technique to calculate volatility.
  • This is calculated by adding the daily price changes together and dividing the result by the number of days.
  • After that, you will need to subtract the daily price variation from the average price change.
  • Due to the fact that price changes are sometimes below average, some of these will be negative.
  • Square these deviations in order to eliminate all the negative values and work with only positive figures.
  • To get the variance, add these figures and divide by the number of days.
  • To get the standard deviation, take the variance and square root it. This standard deviation is often used to determine volatility. Traders may profit from high volatility by buying and selling currency pairs.

A currency pair's volatility may be confirmed by using standard deviation combined with the following technical indicators.

Volatility Indicator on MT4: Average True Range

The average true range (ATR) is a volatility indicator calculated using three basic calculations.

  • Firstly, you subtract the current day's low from the present day's high to get to the ATR.
  • Then, you deduct the previous day's close from today's high
  • Finally, the last step requires you to subtract the current day's low of the prior day's close to get three different numbers.

The average true range of a currency pair is the greatest of the three values. The greater the figure, the greater the projected volatility for that currency pair.


Beginners may rapidly learn how to utilize ATR in their trading strategy, and this volatility measuring tool can also assist you in creating stops and price goals depending on volatility strength.


While ATR is a simple formula for traders to utilize, it does have limits. The ATR, for example, doesn't really identify the direction of movement for a hypothetical price swing; it merely evaluates the possibility of that price swing occurring.

The ATR is also a trailing indication rather than a leading indicator. It takes longer to uncover attractive trading opportunities—a drawback if you want to rapidly profit from market volatility.

Example on MT4

Volatility Indicator on MT4: Bollinger Bands

This volatility indicator is a metric that goes two standard deviations (around 95 percent) below and above the moving average of 20-days.

When the gap between the bands increases, it sends out an indication that the currency that you are examining is experiencing more market volatility. If the gap is shorter, it indicates less volatility.

Traders may use Bollinger Bands not only to gauge overall volatility for a forex listing but also to utilize the closeness of the candle to one of the bands.

When a candle reaches or approaches a Bollinger Band, it indicates a substantial potential for a retracement, and traders may be enticed to initiate a position in the hopes of profiting from the next movement.


Bollinger Bands may be set to monitor three standard deviations over a more extended time period.


Bollinger Bands, like other technical indicators, depend on previous data, which may be meaningless if volatility is influenced by current events.

Volatility Indicator on MT4: Keltner Channel

This is a volatility indicator that examines price fluctuations in relation to a forex currency pair's lower and higher moving averages. This indicator is a hybrid of the ATR and the exponential moving average (EMA).

Although the Keltner Channel seems similar to Bollinger Bands, the proper technique to apply this indicator to examine volatility necessitates a distinct strategy.

The Keltner Channel is substantially narrower than the Bollinger Bands, which are two standard deviations above the 20-day moving average: Its range is determined by drawing a band on each side of the 20-day EMA that is twice the size of the ATR.

Price moves that happen to break above or below these Keltner Channel lines should be monitored by traders. 

This signals that prices are likely to continue trending in that way, providing some quick profit-taking on imminent instability.


Even if price activity does not approach the Keltner Channel's boundaries, decreased activity may represent reducing price volatility.


The Keltner Channel is generally slower than other indicators, notably Bollinger Bands, in detecting volatility.

Volatility Indicator on MT4: Parabolic Stop And Reverse

The last volatility indicator in this list is the parabolic stop and reverse.

A parabolic stop and reverse pattern is a forex chart pattern that generates a parabolic curve with dots that appear below or above the price depending on the price's trend movement.

Traders may detect trading opportunities by observing variations in the positioning of the dots.

When the dots change from above to below the price, it indicates that trading activity is producing upward momentum, resulting in a buying opportunity.

When the dots change from below to above, it might signal a movement that indicates a selling opportunity.

This indicator may assist traders in making sense of unpredictable market circumstances and identifying chart patterns that may bring potential profit.


PSAR provides a clear visual interpretation that makes evaluating and tracking volatility straightforward.


When volatility and price momentum are not matched, PSAR's indicators may change too often to be useful for traders attempting to use it to evaluate volatility.

Conclusion to Volatility Indicators on MT4

In forex, volatility may be your greatest friend or your worst enemy—it all depends on how you comprehend it and how you try to profit in these market circumstances while reducing your risk.

These volatility indicators can assist you in gaining a better understanding of an uncertain scenario, which may lead to some opportune trades that transform volatility into a profitable prospect.
