The Most Important Technical Indicators in Forex Trading

There are lots of different indicators on the Forex market and they range from the simplest to the most complicated indicators. We will talk about the four most popular trading indicators in Forex:
 

  • Moving Average
  • Moving Average Convergence/Divergence (MACD)
  • Bollinger Band
  • Fibonacci Retracement

 
Moving Average is probably the simplest Forex indicator traders can use to make certain observations on the market. With it, they can determine the simple trend of the market - whether it is expanding or shrinking. The Moving Average is basically an average (or mean) of all the individual prices in the data set and contains two separate indicators: Simple Moving Average (SMA) and Exponential Moving Average (EMA).
 
The Moving Average Convergence/Divergence (MACD), as the name suggests, is associated with the Moving Average indicator. The MACD indicates not only the existing trend, but it also shows how strong that trend actually is. This way, traders are more aware of when to buy or sell an asset.
 
Just like the MACD, the Bollinger Band also uses the Moving Average to make assessments of a trend. Basically, the Bollinger Band detects the standard deviation of the price and indicates whether a completely new trend has begun or not. With it, traders detect the actual volatility of an asset.
 
As for the Fibonacci Retracement, this indicator also helps traders predict the future price movement of an asset. It does that with the famous mathematical sequence called Fibonacci. The idea behind this indicator is that whenever the price makes an extreme move, it tends to go back to its prior place by a level indicated by the Fibonacci Retracement.

The most important indicators in Forex

In Forex, as well as other trading markets, there are lots of different elements that influence trading outcomes. Traders can use different kinds of charts for technical analysis, automate their trades with trading bots (Expert Advisors, cBots, etc.), or use technical indicators to make better predictions about the future price movements.
 Best indicator in Forex
When it comes to Forex indicators, there is a huge selection of them, both pre-existing and custom made. Many pieces of software, including MetaTrader or cTrader, allow traders to create their own technical indicators and incorporate them into the platform. Therefore, there is no shortage of these indicators at all.
 
As for the most important indicators, it all comes down to what traders choose for their specific trades. However, there are still some indicators that are widely known and used across the platform. These are:
 
  • Moving Average (Simple and Exponential)
  • Moving Average Convergence/Divergence (MACD)
  • Bollinger Band
  • Fibonacci Retracement
 
We will discuss these technical indicators in this article.


The Moving Average

First off, let’s start with probably the most basic technical indicator, the Moving Average. This indicator uses the historical price movements of an asset and offers traders their average (mean).
 
The Moving Average itself can be divided into two different indicators: a Simple Moving Average (SMA) and an Exponential Moving Average (EMA). The SMA and EMA can be considered the top Forex indicators because in many cases, they also help create other indicators.
Important indicators in Forex
 

A Simple Moving Average

The SMA is just an average of all the prices that occurred in a given period of time. For example, if we want to get a Simple Moving Average for 20 days, we have to get a sum of every price in this set and then divide them by 20, which gives us the mean of the closing prices during those 20 days.
 
The SMA is a so-called “lagging” indicator because it offers the trend for the historical prices after the trend has already begun. What’s more, the SMA isn’t the best indicator in Forex for identifying the influence a sudden price change has on the overall trend. The reason for that is that as time goes on and the number of individual prices increases, the average number becomes less sensitive - an additional price doesn’t affect this number that much.
 
But this doesn’t mean that the SMA has no use. It is a very useful indicator for actually confirming a trend. Usually, the Simple Moving Average operates with two data sets (sometimes more): one for a shorter time period and one for a longer time period.
 
When the long-term average crosses the short-term average, the SMA indicates the beginning of a new trend. We have an uptrend if the long-term line is moving above the short-term line, and we have a downtrend if the long-term line is moving below the short-term line.


An Exponential Moving Average

The EMA is quite similar to the SMA in that it also offers the average of the historical prices. However, at the same time, this indicator focuses more on recent prices and is more sensitive to the current price changes. That’s why in this list of Forex indicators, the EMA is more widely used for making sophisticated predictions.
 
Typically, short-term averages use 12-day and 26-day data sets, whereas long-term averages have 50-day and 200-day data sets. Similar to the SMA, the trading signals occur when the lines cross each other. If the shorter moving average (MA) crosses the slower MA and goes above, the signal suggests buying an asset. And if the shorter MA crosses below the slower MA, the signal will suggest selling an asset.


The Moving Average Convergence/Divergence (MACD)

This next technical indicator, as its name suggests, also uses the average levels to identify a trend. But it doesn’t just stop at that: the MACD goes as far as giving the strength/momentum of that trend. It does that by calculating the difference between the faster and slower EMAs.
Which Forex indicators to use
Basically, the MACD line can be calculated by subtracting the 26-day EMA from the 12-day EMA, which gives us the strength of the trend. Then, a 9-day EMA is put in the chart as a signaling line. When the MACD line crosses above the signal line, the indicator gives out a buying signal, whereas the crossing below the signal line will give out the selling signal.


The Bollinger Band

The previous indicators mainly focused on providing the average level of the previous prices. As for which Forex indicators to use for calculating the volatility of an asset, the Bollinger Band is probably the best choice.
 
The Bollinger Band is a volatility channel that signals the amount of change an asset took from the average point. In short, this indicator uses standard deviations to offer the volatility of a currency pair or another asset.
Top indicators in Forex
Visually, the Bollinger Band consists of three lines - one moving average and two standard deviation lines. The two deviation lines indicate how far the asset prices diverge from the average price. This way, traders get more specific data about the shifts in prices.


Fibonacci Retracement

Finally, let’s talk about Fibonacci Retracement and how to use Forex indicators like that in actual trades. First off, we have to note that Fibonacci Retracement is based on the famous Fibonacci sequence that has been known to humanity from ancient times, but was officially systematized by the Italian mathematician, Fibonacci. The sequence begins with 0 and 1 and the next numbers are the sums of the previous two numbers. This is how this goes: 0, 1, 1, 2, 3, 5, 8, 13…
 
The idea behind Fibonacci Retracement is the belief that when the market makes an extreme move - whether it’s a sudden increase or sudden decrease in price, - the chances are, it will soon go back to its prior position by the given ratios.
 
These ratios come from the numbers in the Fibonacci sequence. The key ratio is 0.618, or 61.8%. It can be calculated by dividing a number from the sequence by the next number immediately following it in the same sequence. As we move forward in the Fibonacci set, the ratio increasingly moves closer to 61.8%. For example, 34/55=0.61818 and 144/233=0.61802.

The next important ratio is 0.382, or 38.2%. We get this ratio by dividing a number by the one that is two places ahead of it in the sequence. For instance, 55/144 or 89/233. Again, we get closer to this ratio as we move forward in the sequence. There’s also a 0.236 ratio (23.6%) which is a ratio between a number to the one that’s three places ahead of it.
 
So, the idea behind all these numbers and ratios is that after a drastic price move, that same price will probably get back to where it was and the amount by which it will retract will coincide to the Fibonacci ratios. Using the Fibonacci Retracement, traders can make certain predictions as to how the price of a given asset will increase/decrease after a major price move.

The best indicators to trade Forex - Key takeaways

When traders use indicators in Forex or in any other market, their goal is to analyze the historical price movements and predict future movements at a certain accuracy. While there are lots of top indicators in Forex, we chose four of the most popular ones for this article: Moving Average (Simple and Exponential), Moving Average Convergence/Divergence (MACD), Bollinger Band, and Fibonacci Retracement.
 
The Moving Average is an indicator that is used to define previous trends in price movements. The Simple Moving Average (SMA) is a mean of all the individual prices in a given time period and so is the Exponential Moving Average (EMA). The difference between the two is that the EMA is more sensitive to the current price changes and gives a more accurate representation of the current market conditions.
 
The Moving Average Convergence/Divergence uses the same EMA for determining the trend. Yet it goes even further and offers the strength of that trend, which makes it one of the most sophisticated moving average indicators in the industry.
 
The Bollinger Band is a volatility channel indicator that provides the trend, as well as the amount of price shift of a given asset. It uses standard deviation to determine how far the actual price has deviated from the average price.
 
Fibonacci Retracement uses the famous Fibonacci sequence to predict the price retraction after the major market development. According to this indicator, when a price suddenly increases or decreases, it will get back to its place by the amount set by the Fibonacci ratios.
 

FAQ on the most important Forex indicators

1.What are the best Forex indicators for beginners?

When it comes to choosing an indicator when you’re just starting in Forex, it is probably a good idea to get to know the most basic indicators: the Moving Averages. Although, it’s not to say that other indicators are too difficult and not usable for the beginners.
 
The Moving Average consists of two sub-indicators: a Simple Moving Average (SMA) and an Exponential Moving Average (EMA). Both of these indicators offer an average/mean number of the prices in a given time period.
 
However, there is a significant difference between the two: the SMA is less sensitive to the current price movements because it usually includes many individual elements, therefore, a single element cannot have a big effect on the overall average. The EMA, however, offers shorter timeframes and is more sensitive to sudden changes.


2.What is the best Forex trading indicator for calculating the volatility?

Volatility channel is one of the most important elements in Forex, as well as stock, commodities, and other markets. And there are lots of indicators that calculate it, one of which is the Bollinger Band.
 
The Bollinger Band uses standard deviations to depict shifts in asset prices. The band consists of three lines: one moving average and two standard deviations. The higher the volatility, the wider the band; conversely, the lower the volatility, the shallower the band.
