The Double Exponential Moving Average is a technical indicator that uses two exponential moving averages (EMAs) to eliminate lag, as some traders view lag as a problem. The Double Exponential Moving Average is used in a similar way to traditional moving averages (MA). The DEMA can be used in the same way as other MAs, as long as the trader understands the indicator will react quicker than traditional MAs.
DEMA = (2*ema(data, period) – ema(ema(data, period), period)
How to use:
The Double Exponential Moving Average helps confirm uptrends when the price is above it and helps confirm downtrends when the price is below it. When the price crosses the average that may signal a trend change. The DEMA responds quicker to price changes than a normal exponential moving average.
The DEMA can be used as a stand-alone indicator and can be incorporated into other technical analysis tools whose logic is based on moving averages.
DEMA can also be used to analyze the strength of an uptrend or downtrend in price.
- When the price moves above the DEMA from below that could signal the downtrend is over and the price is starting to rise. Hence one can go long if the price crosses above the DEMA.
- When the price moves below the DEMA from above that could signal the uptrend is over and the price is starting to fall. Hence one can go short if the price crosses below the DEMA.
