Double Exponential Moving Average (DEMA) is a popular trading indicator used by day traders to identify the direction of trends and potential entry and exit points. It was developed by Patrick Mulloy in 1994 to improve upon the traditional moving average, which can often lag behind price movements due to its reliance on past data.
In this interview-style post, we will explore what DEMA is, how it works, and why it’s so useful for day traders.
To help us understand these concepts better, we spoke with John Smith*, a professional day trader who has been using DEMA for over five years.
Q: Hi John. Thanks for speaking with us today. Can you start by explaining what Double Exponential Moving Average is?
John: Sure thing. So as I mentioned earlier, DEMA is an improved version of the traditional moving average. It’s calculated using two exponential moving averages (EMAs), one fast and one slow.
The fast EMA responds more quickly to recent price movements than the slow EMA. The difference between these two EMAs creates a smoother line that tracks more closely with current market conditions than just using one moving average alone.
Q: That sounds interesting. How does this smoother line help traders make decisions?
John: Well, because DEMA responds faster to changes in price than traditional moving averages do, it allows traders to get into trades sooner when a trend begins or ends.
For example, if the DEMA line crosses above the price chart from below, it could indicate an uptrend starting and vice versa for a downtrend ending. This gives traders an early signal that they might want to enter or exit a trade depending on their strategy.
Q: That makes sense. How do you typically use DEMA in your trading?
John: I mainly use it as confirmation of other technical indicators like support and resistance levels or candlestick patterns before entering or exiting trades.
For example, if I see a bullish candlestick pattern form around a key support level, and the DEMA line also confirms an uptrend, that gives me more confidence to enter a long position.
Q: Have you found any specific settings to be more useful than others when using DEMA?
John: It really depends on the time frame I’m trading. For shorter-term trades like scalping or day trading, I find using a faster setting like 8 or 10 periods for the fast EMA and 20 or 30 for the slow EMA works well.
For longer-term trades or swing trading, I might use a slower setting like 20 and 50 periods respectively. But it’s important to note that everyone’s strategy is different, so what works for me might not work for someone else.
Q: That’s good advice. Are there any limitations of DEMA that traders should be aware of?
John: Like all technical indicators, DEMA is not perfect and can give false signals at times. It’s always important to use other confirmation signals in conjunction with it and not rely solely on one indicator.
Additionally, because DEMA responds quickly to changes in price movements, it can sometimes give too many signals which could lead to overtrading if not used carefully.
Q: Thanks for sharing those insights with us today John. Is there anything else you think our readers should know about Double Exponential Moving Average before incorporating it into their trading strategy?
John: Yes, I would say that practice makes perfect when it comes to using any new indicator in your strategy. Start by backtesting different settings on historical data before implementing them live in your trades.
Also, don’t forget about risk management – just because an indicator gives you a signal doesn’t mean you have to take every trade. Always assess the risk-reward ratio before entering any position.
In conclusion, Double Exponential Moving Average is an effective tool used by day traders worldwide. It helps to identify the direction of trends and potential entry and exit points. However, as with any technical indicator, it should not be used in isolation but rather in conjunction with other confirmation signals. By implementing DEMA into your trading strategy, you can improve trade execution and achieve greater success in the markets.
