Double Exponential Moving Average (DEMA)

In the world of technical analysis and trading, moving averages play a crucial role in identifying trends and potential entry and exit points. One popular variation of the traditional moving average is the Double Exponential Moving Average (DEMA). In this article, we will delve into what DEMA is, how it differs from other moving averages, and how traders can effectively use it to enhance their trading strategies.

Understanding Moving Averages

Before we dive into the specifics of DEMA (Double Exponential Moving Average), it’s essential to have a clear understanding of moving averages in general. A moving average is a widely used technical analysis tool that helps to identify trends and potential entry or exit points in the financial markets.

A moving average is a statistical calculation that smooths out price data by creating a constantly updated average price over a specific time period. It is called “moving” because it continuously recalculates as new data points are added and older data points are dropped. The concept behind a moving average is that it helps to filter out short-term fluctuations or noise in the price data, therefore providing a clearer picture of the underlying trend.

There are different types of moving averages, with the simple moving average (SMA) being the most basic form. The SMA calculates the average of the closing prices over a specific number of periods and is widely used by traders and analysts. However, the SMA has some drawbacks, as it tends to lag behind price movements and may be slower in responding to sudden price changes.

This is where the DEMA comes into play. The DEMA is a more advanced moving average that aims to reduce lag and provide a more responsive indicator. It achieves this by applying a double smoothing technique to the price data. The formula for calculating the DEMA involves multiple steps, but in essence, it applies the smoothing process twice to create a more sensitive moving average.

By using the DEMA, traders and analysts can potentially have a better understanding of the current market trend and make more informed decisions. It is worth noting that like any technical indicator, the DEMA is not foolproof and should be used in conjunction with other tools and analysis methods.

In conclusion, moving averages are a fundamental tool in technical analysis, and the DEMA is an advanced variation that seeks to improve upon the shortcomings of the simple moving average. Understanding how moving averages work and how to interpret them can be beneficial for traders and investors looking to make sense of price movements in the financial markets.

Simple Moving Average (SMA)

The Simple Moving Average (SMA) is a widely used technical indicator in financial analysis. It is a straightforward calculation that helps to smooth out price data over a specified time period.

The concept behind SMA is to calculate the average price over a certain period, which could be days, weeks, months, or any other timeframe of interest. By taking the average, it helps to filter out the noise and fluctuations in price, providing a clearer picture of the overall trend.

Traders and investors use SMA to determine the direction of the market. If the current price is above the SMA, it suggests a bullish trend, indicating that the price may continue to rise. Conversely, if the price falls below the SMA, it indicates a bearish trend, suggesting that the price may continue to decline.

SMA can also serve as a support or resistance level. Traders often look for price bounces or breakouts around the SMA, which can provide trading opportunities.

It’s important to note that SMA is a lagging indicator, meaning it may not provide timely signals for short-term traders. To address this, some traders use multiple SMAs of different timeframes to generate crossover signals, where a shorter-term SMA moves above or below a longer-term SMA, indicating a potential change in trend.

In conclusion, the Simple Moving Average is a versatile tool used by traders and investors to analyze market trends, identify potential reversals, and determine support and resistance levels. It is a foundational indicator in technical analysis and can be combined with other indicators to build a comprehensive trading strategy.

Exponential Moving Average (EMA)

The Exponential Moving Average (EMA) is a widely used technical indicator in financial markets. It is considered to be a powerful tool in analyzing price trends and identifying potential entry and exit points for traders and investors.

Unlike the Simple Moving Average (SMA), which assigns equal importance to all data points, the EMA gives more weight to recent data points. This characteristic makes it more responsive to the most recent price changes, enabling traders to capture short-term trends effectively.

The EMA is calculated by applying a formula that incorporates previous EMA values and the current price data. By smoothing out price fluctuations and reducing the impact of older data, the EMA provides a more accurate representation of the current market sentiment.

Traders often use the EMA in combination with other technical indicators and chart patterns to validate signals and make informed trading decisions. For example, when the price of an asset crosses above the EMA, it could be seen as a bullish signal, indicating a potential upward trend. Conversely, a price crossing below the EMA might suggest a bearish trend.

It’s important to note that the EMA is not a standalone indicator and should be used in conjunction with a comprehensive trading strategy. Proper risk management and thorough analysis of other factors, such as market conditions and fundamental factors, are crucial for successful trading.

In summary, the Exponential Moving Average is a valuable tool for traders and investors seeking to identify short-term trends and make informed trading decisions. Its ability to adapt quickly to changing market conditions makes it a popular choice among technical analysts.

Introducing the Double Exponential Moving Average (DEMA)

The Double Exponential Moving Average (DEMA) takes the concept of the EMA one step further by applying the EMA calculation twice. The objective of DEMA is to reduce lag and provide faster and more precise signals than traditional moving averages.

DEMA Calculation

The DEMA calculation involves the following steps:

  1. Calculate the EMA of the price data for a specified period (EMA1).
  2. Calculate the EMA of the EMA1 calculated in step 1 (EMA2).
  3. Calculate the DEMA using the formula: DEMA = 2 * EMA1 – EMA2

The result is a DEMA line that oscillates around the price chart, capturing price movements with greater sensitivity.

Advantages of DEMA

DEMA offers several advantages over other moving averages:

Reduced Lag

DEMA significantly reduces lag compared to both SMA and EMA. This means DEMA is more responsive to changes in price, allowing traders to enter and exit positions with improved timing.


DEMA’s dual EMA calculation leads to a smoother and more visually appealing line on the price chart. This smoothness can make it easier for traders to interpret and act on signals.

Enhanced Trend Identification

DEMA excels at identifying trends in the market. Its ability to respond quickly to price changes helps traders catch trend reversals early on.

Using DEMA in Trading Strategies

Traders use DEMA in various ways to build trading strategies. Here are some common approaches:

DEMA Crossovers

One popular strategy involves monitoring the crossover of the DEMA line and the price chart. When the DEMA crosses above the price chart, it could signal a bullish trend, and when it crosses below, it could indicate a bearish trend.

DEMA with Other Indicators

Traders often combine DEMA with other technical indicators to validate signals and reduce false positives. Combining DEMA with indicators like the Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD) can enhance the accuracy of trading decisions.

Support and Resistance Levels

DEMA can act as dynamic support and resistance levels. Traders observe how the price interacts with the DEMA line and use it as a basis for potential trade setups.


The Double Exponential Moving Average (DEMA) is a powerful tool in a trader’s arsenal. Its ability to reduce lag, smooth out price data, and identify trends makes it a valuable addition to any trading strategy. As with any technical indicator, it is essential to test DEMA thoroughly and combine it with other tools for the best results.


Can DEMA be used in conjunction with other moving averages?

Yes, traders often use DEMA along with other moving averages to gain additional insights into market trends.

What is the optimal period for DEMA?
