This is the formula for working out the multiplier, which can then be used in the calculations for the EMA: A multiplier is then added that increases the weighting of the newer price data. To work out an EMA, you start with the SMA data. The oldest price bar, number 1, only accounts for 3%. 10 price bars are used for this particular example.Īs you can see, the most recent price bar, number 10, accounts for 18.2% of the average.
To illustrate the emphasis placed on newer data, the below table shows the percentage of the EMA that is made up by each of the price bars. An EMA’s main benefit is the speed with which it reacts to the markets, but it requires some caution too – it might look like a trend is forming, when actually it’s just a price spike. They reduce the effect of the lag that comes from using previous price data and can help you identify a trend earlier, so it’s a useful indicator for trading short-term contracts. Exponential moving average (EMA)Įxponential moving averages, or EMA, give more weighting to recent prices. closing prices from the last ten days), you would add these together and divide the total by ten. If, for example, you have ten price inputs (i.e. In the instance of an SMA, these inputs will be closing prices.

How to calculate SMAĪn SMA is exactly what the name implies: it’s the average of a set number of inputs, as chosen by the trader. It will show you an average of price action over a set period of time. If you are trading binary option contracts with longer time frames, or week-long knock-outs/ call spread contracts, you may choose to use this average. Simple moving averages, or SMA, are generally the choice of the longer-term trader. There will be a distinct difference between SMA and EMA over a longer time period. Traders with a short-term perspective will usually get similar results with whichever average they use, whereas traders with a long-term perspective need to carefully determine what they need their indicators to show them. Due to the way they’re calculated, EMA give more weighting to recent prices, which can potentially make them more relevant. SMA are the most commonly used averages, but there are cases where EMA might be more appropriate.

The main practical difference between a simple moving average and an exponential moving average is the calculation that is performed.
The data sets that are used to form the average are continuously replaced by new data, which is why it’s called a moving average.
For this reason, they are often used alongside other technical indicators, underpinning them to provide a more in-depth analysis. Moving averages use previous price data, so they lag behind current trends. Rather than predicting new trends, they tend to be used to confirm them – if price bars move in the same direction as their moving average, they are easier to verify. They work by smoothing out price bars, giving an average over a predefined time period, so traders have a clearer overview of what is happening in the markets. Simple moving averages (SMA) and exponential moving averages (EMA) are technical indicators used in market analysis, helping traders gain a better understanding of trends.
