Double Exponential Moving Average (DEMA)

The Double Exponential Moving Average (DEMA) combines a smoothed EMA with a single EMA to provide a diminished amount of delays (than if the two moving averages had been used apart). This is calculated as follows DEMA = 2*EMA – EMA(EMA). The user may change the input (close), period length and shift number. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using the Double Exponential Moving Average

The Double Exponential Moving Average is a lagging trend indicator and may be used in conjuction with other studies. No trading signals are calculated.

Calculation

//input = price, user defined, default is close
//period = user defined, default is 20
//shift = user defined, default is 0
//dema = double exponential moving average
//index = current bar number
