The formula for calculating the Exponential Moving Average (EMA) is shown below.

How Is the Exponential Moving Average (EMA) Formula Calculated?
The exponential moving average (EMA) is a technical analysis tool forex traders use to smooth out price fluctuation in the market. Unlike the simple moving average (SMA), the EMA gives more weight to the most recent price data when calculating the moving average value of price action. For this reason, the EMA line follows price action more closely and is more accurate in identifying a trend direction than other moving average indicators. Exponential Moving Averages (EMAs) are a valuable tool in forex trading for identifying trends, determining entry and exit points, and identifying support and resistance levels.

Conversely, when the price approaches the EMA resistance level in a downtrend, it can be a potential area to enter a short trade with a tight stop-loss above the EMA. A fundamental method of trading with the EMA is to identify trends and crossovers in price action. Conversely, a downward movement of the EMA indicates a bearish run of price action.
Using EMAs in Forex Trading
A trader would then enter a buy order when the short-term EMA crosses above the long-term EMA or enter a sell order when the short-term EMA crosses below the long-term EMA. We introduce people to the world of trading currencies, both fiat and crypto, through our non-drowsy educational content and tools. We’re also a community of traders that support each other on our daily trading journey. For instance, if you are a swing trader, you may want to hold the trade for a long period, seeing that it can be the beginning of a new trend. But for this illustration, we advise that you set a minimum of 1.5 Risk-reward ratio for profit targets.
To traders, the most recent price action is more significant than earlier data. Like all moving average indicators, EMAs are much better suited for trending markets. When the market is in a strong and sustained uptrend, the EMA indicator line will also show an uptrend and vice-versa for a downtrend. A vigilant trader will pay attention to both the direction of the EMA line and the relation of the rate of change from one bar to the next.
Moving averages can be very useful for traders using technical analysis for profit. It is important to identify and realize, however, their shortcomings, as all moving averages tend to suffer from recurring lag. Foreign currency traders use a number of tools to help them establish buy and sell points for the currencies they trade based on price trends.
An exponential moving average (EMA) is a type of moving average (MA) that places a greater weight and significance on the most recent data points. The exponential moving average is also referred to as the exponentially weighted moving average. The 20 EMA is indeed considered a good indicator for finding trade signals, especially due to its emphasis on recent price data. This makes the 20 EMA more responsive to new information than a simple moving average, which can be advantageous in a fast-moving market. The 200-period EMA is a widely-watched indicator for long-term trend direction, usually being a part of the position trading strategy.
- With the Guppy system, you could make the short-term moving averages all one color, and all the longer-term moving averages another color.
- If one of the values is an outlier, the resultant value of the SMA will be severely distorted.
- The idea is simple and works the same as many other EMA strategies, including the popular 9 EMA trading strategy.
If the smoothing factor is increased, more recent observations have more influence on the EMA. The Exponential Moving Average is equal to the closing price multiplied by the multiplier, plus the EMA of the previous day and then multiplied by 1 minus the multiplier. With this in place, it becomes clearer to traders coinjar review what the market is doing NOW rather than what it did in the past. Sometimes referred to as the FX, it is a global, 24-hour marketplace for the trading of currencies. It is electronic and decentralized, having no owners and no headquarters.
On the TradingView platform, the EMA is a built-in indicator that can be easily added to your chart. To add the 20 EMA, you can select the ‘Indicators’ option on your chart, search for ‘Exponential Moving Average’ and add it. As shown below, you then adjust the settings to ’20’ to reflect the 20-day period. For example, the Georgia Rural Health Innovation Center was able to track the incidence of COVID-19 cases in the region by charting the moving average of cases.
There are also slight variations of the EMA arrived at by using the open, high, low, or median price instead of using the closing price. Suppose that you want to use 20 days as the number of observations for the EMA. On the 21st day, you can then use the SMA from the previous day as the first EMA for yesterday.
The opposite is true if the moving averages are fanning and moving apart from each other, suggesting that prices are ranging and that a trend is strong or strengthening. For example, an 18.18% multiplier is applied to the most recent price data for a 10-day EMA, as we did above, whereas for a 20-day EMA, only a 9.52% multiplier weighting is used. However, it is important to note that this strategy should not be used in isolation. It is recommended to combine it with other technical indicators or price action analysis to confirm the signals and minimize false signals. To implement this strategy, you can use a shorter-term EMA (e.g., 20-day EMA) and a longer-term EMA (e.g., 50-day EMA). When the shorter-term EMA crosses above the longer-term EMA, it generates a buy signal, indicating a potential uptrend.
This would mean that the spike on Day 2 would be of lesser value and wouldn’t have as big an effect on the moving average as it would if we had calculated for a simple moving average. The trading rules for getting an entry with this strategy are pretty straightforward and mechanical. The first thing you want to look out for when you hit the chart is to check if the RSI indicator is showing the market as oversold or overbought. Once we have our setup in place, we can determine which timeframe is best for us, depending on our trading style. In this article, we will introduce you to the 20 EMA strategy, showing you everything from how to set it up to explain how to place a trade with it.
As such, this combination is often used by traders who utilize the intraday trading strategy. Traditional buy or sell signals for the moving average ribbon are the same type of crossover signals used with other moving average strategies. Numerous crossovers are involved, so a trader must choose how many crossovers constitute a good trading signal. The moving average ribbon can be used to create a basic forex trading strategy based on a slow transition of trend change. Traders and analysts rely on moving averages and ribbons to identify turning points, continuations, and overbought or oversold conditions. They also can be used to define areas of support and resistance and to measure the strength of price trends.
That is because it more accurately represents recent price action and places greater significance on the most recent days. In our next lesson, we’ll compare the simple and exponential moving averages more exhaustively and help you determine which suits your trading style better. The creation of the moving average ribbon was founded on the belief that more is better when it comes to plotting moving averages on a chart. The ribbon is formed by a series of eight to 15 exponential moving averages (EMAs), varying from very velocity trade short-term to long-term averages, all plotted on the same chart.
