# Double Exponential Moving Average (DEMA) Definition and Calculation.

A double exponential moving average (DEMA) is a type of moving average that places more weight on recent data points than a simple exponential moving average (EMA).

The double exponential moving average is calculated by applying a weighting factor to the standard exponential moving average. The weighting factor is based on the exponential decay of a hypothetical security.

The double exponential moving average is less sensitive to price changes than the standard EMA, which makes it a more reliable indicator for trend changes.

The disadvantage of the double exponential moving average is that it is slower to react to price changes than the standard EMA.

The double exponential moving average is used in conjunction with other technical indicators to generate buy and sell signals.

#### What is an exponential moving average?

An exponential moving average (EMA) is a type of moving average that gives more weight to recent prices in an attempt to make it more responsive to new information.

The exponential moving average is calculated by applying a percentage of the current price to the previous moving average. The percentage applied is known as the "smoothing factor"

For example, if the current price is 100 and the previous moving average was 90, then the new exponential moving average would be calculated as follows:

New EMA = (Current Price x Smoothing Factor) + (Previous EMA x (1 - Smoothing Factor))

So, if the smoothing factor was 0.3, the new exponential moving average would be calculated as follows:

New EMA = (100 x 0.3) + (90 x (1 - 0.3))

New EMA = 30 + 63

New EMA = 93

As you can see, the new exponential moving average is much closer to the current price of 100 than the previous moving average of 90. The larger the smoothing factor, the more weight that will be given to the current price.

##### How do you trade with DEMA?

The Double Exponential Moving Average (DEMA) is a technical indicator that is used to smooth out price data by creating a constantly updated average. The DEMA is similar to the Exponential Moving Average (EMA), but it places more weight on recent data.

The DEMA can be used in a number of different ways, but one common use is to help identify trends. When the DEMA is rising, it indicates that prices are generally moving higher, and when the DEMA is falling, it indicates that prices are generally moving lower.

Another common use for the DEMA is to help spot potential turning points in the market. When the DEMA crosses below the price data, it can be a signal that prices are about to start falling. Similarly, when the DEMA crosses above the price data, it can be a signal that prices are about to start rising.

The DEMA can also be used as a trailing stop-loss level. When prices start to fall, the DEMA can be used to help identify when to exit a trade.

There is no one perfect way to trade with the DEMA, but using it in conjunction with other technical indicators can help give you an edge in the market. How is moving average used in trading? The moving average is a simple technical indicator that smooths out price action by creating a constantly updated average price. This average price is often used as a key indicator to help traders assess price direction and spot potential trading opportunities.

There are two main types of moving averages: the simple moving average (SMA) and the exponential moving average (EMA). The SMA is the most common type of moving average, and it is calculated by taking the average of a given set of prices over a certain period of time. The EMA, on the other hand, places more weight on recent price data, which makes it more responsive to recent price changes.

Moving averages can be used in a number of different ways, but one of the most common uses is to help identify trend direction. A trader might look for a situation where the price is above the moving average, which would indicate an uptrend, or below the moving average, which would indicate a downtrend.

Another common use for moving averages is to help spot potential trading opportunities. For example, a trader might look for a situation where the price is starting to move away from the moving average, which could be a sign that a new trend is developing.

There are a number of different ways to use moving averages, and different traders will have their own preferences. It is important to experiment with different settings and see what works best for you. What are the most important moving averages? There is no definitive answer to this question, as different traders place different levels of importance on different moving averages. However, some of the most commonly used moving averages are the 10-day, 20-day, 50-day, and 200-day simple moving averages (SMAs). These averages are popular because they provide a good balance between short-term and long-term perspectives.

The 10-day SMA is a good choice for traders who want to focus on the short-term, as it will give them a good idea of the recent price action. The 20-day SMA is a good choice for traders who want to focus on the intermediate-term, as it will give them a good idea of the overall trend. The 50-day SMA is a good choice for traders who want to focus on the long-term, as it will give them a good idea of the long-term trend. The 200-day SMA is a good choice for traders who want to focus on the very long-term, as it will give them a good idea of the long-term trend.

Moving averages are just one of many technical indicators that traders can use, and there is no one “best” moving average. The most important moving average is the one that works best for the individual trader’s trading style and timeframe.

##### What is 200 DMA in stock market?

The 200 day moving average (200 DMA) is a technical indicator that is used by many traders to help them make decisions about when to buy and sell stocks. The 200 DMA is simply the average price of a stock over the past 200 days. Many traders believe that the 200 DMA is a good indicator of a stock's long-term trend, and that if a stock's price is above the 200 DMA, it is likely in a long-term uptrend, and if it is below the 200 DMA, it is likely in a long-term downtrend. Some traders also use the 200 DMA as a support or resistance level, and will buy or sell if the stock price hits the 200 DMA.
