BREAKING DOWN 'Double Exponential Moving Average - DEMA '
The DEMA is a fast-acting moving average that is more responsive to market changes than a traditional moving average. It was developed in an attempt to create a calculation that eliminated some of the lag associated with traditional moving averages. The DEMA can be used as a stand-alone indicator and can be incorporated into other technical analysis tools whose logic are based on moving averages.
