DEMA - Double Exponential Moving Average

The DEMA is a smoothing indicator with less lag than a straight exponential moving average.  DEMA is an acronym for Double Exponential Moving Average, but the calculation is more complex than just a moving average of a moving average.

DEMA offers a moving average with less lags then the traditional EMA. Do not confuse a DEMA with the EMA2. Both are called "Double EMA" in the litterature, but EMA2 is a simple EMA of an EMA, while DEMA is a compostie of a single EMA with EMA2.
