Double Exponential Moving Average (DEMA)


The Double Exponential Moving Average (DEMA) is a financial term used in technical analysis. It’s a faster version of the traditional exponential moving average, calculated by combining a single and double exponential moving average to decrease lag time. The DEMA is used primarily in trading to identify emerging price trends, providing a smoother line with less lag compared to traditional moving averages.


The phonetics of “Double Exponential Moving Average (DEMA)” would be:Double – /ˈdʌb.əl/Exponential – /ɪkˌspoʊ.nenʃəl/Moving – /ˈmuː.vɪŋ/Average – /ˈæv.ər.ɪdʒ/DEMA – /ˈdiː.mə/

Key Takeaways

<ol><li>DEMA is a faster version of a traditional exponential moving average: The Double Exponential Moving Average (DEMA) while similar to traditional moving averages, applies more weight to recent price data. It reacts more quickly to price changes and thus provides trading signals faster than traditional moving averages.</li><li>DEMA provides smoother, less jittery trend signals: DEMA is less prone to erratic behavior, making it especially useful in volatile markets. Its smoothing effect reduces false signals and noise from minute price fluctuations.</li><li>DEMA requires careful implementation and interpretation: Although DEMA provides faster and smoother moving average data, it requires careful interpretation and is more complex to implement than simple and exponential moving averages.

The Double Exponential Moving Average (DEMA) is a crucial term in business/finance because it is a unique technical indicator used by investors and market analysts to predict price trends in volatile financial markets. The DEMA, being more responsive than traditional simple or single exponential moving averages, helps to minimize lag, thus improving the speed of signals given by the moving averages. This smoothens the analysis of financial data and improves the accuracy of forecasting, helping investors understand where the market is heading for more strategic decision-making. Its importance lies in its ability to provide a faster and more precise response to market changes, offering trading advantages in execution speed and potentially improved profitability.


Double Exponential Moving Average (DEMA) is a superior tool utilized in the realm of technical analysis to smoothen a trend line and reduce lag time in the detection of trend changes. Essentially, DEMA focuses on the recent price data with more emphasis, diminishing the impact of outdated data. In essence, it is a tool that aids traders and investors in deciphering future price patterns by eliminating the innate noise in price data.The main purpose of DEMA is to provide an accurate and faster indicator for trend changes, thereby enabling traders to make more prompt investment decisions. A shorter DEMA will react more quickly to changes in the market, making it suitable for short-term trading, whereas a longer DEMA is better for long-term trading as it offers a broader perspective. By presenting a more sensitive reaction to price changes, DEMA empowers investors with the potential to capitalize on opportunities at an earlier stage than traditional single or double moving averages.


1. Stock Trading: Many stock traders, especially day traders, use DEMA to understand stock market trends. For example, a trader looking at Apple Inc.’s stock across a period of time may use DEMA to arrive at an average that is more responsive to recent price changes. This helps traders to react quickly in fast-changing market conditions and make their buy or sell decisions accordingly.2. Commodity Trading: Commodity traders may also use DEMA for their trades. For instance, a gold trader may use DEMA to understand the trend in the gold prices, particularly to identify potential uptrends that can suggest buying opportunities or downtrends that signal selling opportunities.3. Forex Market: Forex traders around the world use DEMA as a fundamental tool for technical analysis to understand and predict changes in currency value trends. A trader dealing with the EUR/USD forex pair, for instance, could use DEMA to decipher the average exchange rate and identify trends. This could potentially provide substantial value in predicting future movement based on DEMA and act accordingly to maximize their profits.

Frequently Asked Questions(FAQ)

What is Double Exponential Moving Average (DEMA)?

Double Exponential Moving Average (DEMA) is a technical indicator used in financial analysis to reduce the lag in traditional exponential moving averages. It is designed to provide faster, more responsive entry and exit signals compared to simple moving averages.

How is DEMA calculated?

The Double Exponential Moving Average (DEMA) is calculated by using the following formula: DEMA = 2 * EMA(n) – EMA(EMA(n)), where n indicates the period of time.

What’s the difference between EMA and DEMA?

The main difference is that DEMA adjusts more quickly to price changes than EMA. As a result, DEMA gives traders earlier signals for market entries and exits, and it also identifies changes in a market trend faster.

How do traders use Double Exponential Moving Average (DEMA)?

Traders use DEMA to identify market trends and potential buying or selling points. The basic idea is that when the price of an asset is above the DEMA line, there is a potential buy signal, and when the price falls below the DEMA line, there’s potentially a sell signal.

Is DEMA a good indicator for volatile markets?

DEMA is especially useful in volatile markets as it quickly reacts to price changes and can help traders detect trend reversals faster than simple moving averages.

Can DEMA be used with other indicators?

Yes, DEMA is often used in combination with other indicators to confirm significant market moves and to avoid false signals. For example, it could be used with Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD) for a more accurate trading strategy.

Does DEMA work for all types of trading?

DEMA can be a useful tool for all types of trading, including swing trading, day trading, and even long-term investing. However, like all technical indicators, it’s important to use DEMA as part of a comprehensive trading strategy, and not relying solely on it.

Can DEMA be used for all asset types?

Yes, Double Exponential Moving Average (DEMA) can be used for various kinds of assets such as stocks, futures, commodities, and forex. However, the appropriateness might differ based on the asset’s nature and market conditions.
