Trading with Exponential Moving Averages
By: Flaka Ismaili October 26, 2022
The EMA gives a higher weight to recent prices, while the SMA assigns equal weight to all values. The weighting given to the most recent price is greater for a shorter-period EMA than for a longer-period EMA. For example, an 18.18% multiplier is applied to the most recent price data for a 10-period EMA, while the weight is only 9.52% for a 20-period EMA. Like all moving averages, this technical indicator is used to produce buy and sell signals based on crossovers and divergences from the historical average. To calculate an exponential moving average using a different number of periods, simply change the value in cell E1. The exponential moving average is a universal trading tool that works in all markets, including stocks, indices, currencies, commodities and cryptocurrencies.
- Moving average ribbons allow traders to see multiple EMAs at the same time.
- There are three steps to calculating an exponential moving average .
- But how to do you condense all the different indicators down to what works for you?
- Exponential moving averages reduce the lag by applying more weight to recent prices.
- For example, a 20-day SMA is just the sum of the closing prices for the past 20 trading days, divided by 20.

The exponential moving average is a valuable tool for traders to help identify trends of a financial instrument over a period of time. However, as it is based on historical data, it is not a credible source for future predictions and traders can be misled by false signals. Therefore, it should be used in conjunction with other forms of technical and fundamental analysis when building an efficient trading strategy. In technical analysis, a moving average is an average of price data over a specific time .
Computing the EMA involves applying a multiplier to the simple moving average . As with all moving averages, exponential moving average has its limitations which we will lay out in this section. EMA gives more weight to current data of a trading period, while SMA calculates the average price data of the entire period. The point we’re trying to make is that sometimes the simple moving average might be too simple.
Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 78% of retail investor accounts lose money when spread betting and/or trading CFDs with this provider. You should consider whether you understand how spread bets and CFDs work and whether you can afford to take the high risk of losing your money. From the chart above, you can see how the EMA line follows closely to the price movements, dipping and rising before the SMA could adjust. We tested 700+ combinations of trend, signal, and lookback period to deliver to you a comprehensive RSI signal database. Moving average ribbons allow traders to see multiple EMAs at the same time.
The exponential moving average is also referred to as the exponentially weighted moving average. that aim to ‘smooth out’ price fluctuations in order to help separate trends from general market activity. The EMA is a popular technical indicator among traders, as it can be applied to all financial markets, including stocks, forex and commodities. The exponential moving average is a weighted moving average that measures a trend, both bullish and bearish, of a financial security over a given period of time.
One characteristic of the SMA is that if the data has a periodic fluctuation, then applying an SMA of that period will eliminate that variation . More specifically, the EMA gives higher weights to recent prices, while the SMA assigns equal weights to all values. The two averages are similar because they are interpreted in the same manner and are both commonly used by technical traders to smooth out price fluctuations. In time series analysis, a moving average is simply the average value of a certain number of previous periods.

For example, the 50ema and the 200ema are used for longer time-frame trend analysis or swing trades. Other EMAs like the 12 and 26 are popular and used for indicators like the MACD . For example, longer-term investors might use higher time-frame exponential moving averages like the 50ema or the 200ema in order to determining the bigger picture trend.
In addition, Murphy shows how moving averages work with Bollinger Bands and channel-based trading systems. Learn about the limitations of using trading systems based solely on moving average crossovers. Another optional parameter can be added to shift the moving averages to the left or right .
Hence, EMAs are best to use in conjunction with other indicators to confirm significant market moves and to gauge their validity. Due to the lagging effect, by this point, the price action should have already reversed. This is because support and resistance levels are dynamic and constantly evolving, due to the fact that they’re based on more recent price action. When the EMA is rising, it is supporting the price action, while the falling EMA is providing resistance to positive price action.
To calculate an exponential moving average, first determine the weight of today’s data point in the EMA calculation. Another difference is that the EMA is slightly more sensitive to price changes compared to the simple moving average. High sensitivity makes it possible for traders to identify a trend faster compared to the SMA. Exponential moving average and simple moving average are similar in that they are used to measure trends.
Exponential Moving Average Explained for Beginners
This means the EMA includes all the price data within its current value. The newest price data has the most impact on the Moving Average and the oldest prices data has only a minimal impact. Keep in mind that EMA is generally more sensitive to price movement.
From there, you can choose between simple, exponential, and weighted moving averages. Once the moving average is added to the chart, you can alter the number of periods, whether it uses the close or the low of the day, and other factors along these lines. An exponential moving average is a technical indicator that uses a multiplier to give preference to newer data points and reduce lag in responsiveness to price movements. Moving averages can also act as support in an uptrend and resistance in a downtrend.

When used with non-time series data, a moving average filters higher frequency components without any specific connection to time, although typically some kind of ordering is implied. A linearly weighted moving average is a type of moving average where more recent prices are given greater weight in the calculation, and prior prices are given less weight. Traders who employ technical analysis find moving averages very useful and insightful when applied correctly. However, they also realize that these signals can create havoc when used improperly or misinterpreted. All the moving averages commonly used in technical analysis are lagging indicators.
This cross lasted longer, but the next bearish crossover in January occurred near late November price levels, resulting in another whipsaw. This bearish cross did not last long as the 10-day EMA moved back above roinvesting review the 50-day a few days later . After three bad signals, the fourth signal foreshadowed a strong move as the stock advanced over 20%. The first day of the moving average simply covers the last five days.
Why are exponential moving averages useful for traders?
You select the SMA indicator from the list of charting indicators and apply it to the chart. forex pivot point strategies can also identify support and resistance levels of prices. Since EMA is super sensitive to price movements, the smaller the time period, the greater the weight. For example, a short-term EMA crossing over a longer-term EMA is a mechanical buy signal for many traders.
In fact, if you look at a chart with a simple moving average and exponential moving average, you might not be able to differentiate between the two at first glance. You can use moving averages for both analysis and trading signals. For analysis, all of the moving averages help highlight the trend.
