Overview
Developed by Patrick Mulloy and introduced in the February 1994 issue of Technical Analysis of Stocks & Commodities magazine, the Double Exponential Moving Average (DEMA) was designed to lessen the lag of a regular exponential moving average. It is a composite of a single exponential MA and a double exponential MA that produces less lag than its two components individually; it is NOT a moving average of a moving average.
As Patrick Mulloy explains: “the DEMA is not just a double EMA with twice the lag time of a single EMA, but is a composite implementation of single and double EMAs producing another EMA with less lag than either of the original two.”

Interpretations and applications of the DEMA are similar to those used on all moving average type indicators.
