Double Exponential Moving Average (DEMA)is a smoothed moving average that results less lag than a traditional Exponential Moving Average (EMA). DEMA is calculated as the difference between doubled value of EMA and the moving average of that EMA.
DEMA = 2 x EMA(n) - EMA (EMA(n)
where: EMA – Exponential Moving Average n – the number of periods (length)

Input
Description
Length
The number of periods the indicator uses to calculate the DEMA
Displace
The number of bars the indicator to be shifted to
Price
The following data sources are available for calculation of DEMA:
Open. The Open Price of every bar for the specified period.
High. The High Price of every bar for the specified period.
Low. The Low Price of every bar for the specified period.
Close. The Close Price of every bar for the specified period.
Median. The Median Price of every bar for the specified period - (High + Low) / 2.
Typical. The sum of High, Low, and Close prices divided by 3 for the specified period- (High + Low + Close) / 3.
OHLC average. The arithmetical mean of High, Low, Open, and Close prices for the specified period - (Open + High + Low + Close) / 4.
Volume. The Close Price of every bar + average volume of an asset for the specified period.
