Double Exponential Moving Average (DEMA) is a well-known trend indicator. DEMA was developed by Patrick Mulloy and published in February 1994 in the "Technical Analysis of Stocks & Commodities" magazine. It is used for smoothing price series and is applied directly on a price chart of a financial security. Besides, it can be used for smoothing values of other indicators. The advantage of this indicator is that it eliminates false signals at the saw-toothed price movement and allows saving a position at a strong trend. (Reference: MT5 Help Topics)
