Exponential Moving Average: The exponential moving average is different to the simple moving average, in that it adds more weight to recent data than it would to old data. Whereas the SMA take all the data over a preconfigured range as the same weight. Say for instance we wanted a moving ...
The exponential moving average gives a higher weighting to recent prices. The simple moving average assigns an equal weight to all values. As with all technical indicators, a trader cannot use one type of average to guarantee success. Simple Moving Average TheSimple Moving Average(SMA) is the m...

One solution to this might be theDouble Exponential Moving Average (DEMA)filter. At a given α the DEMA has faster response than the EMA while still maintaining the same noise suppression. One potential drawback with the DEMA filter is that you might get an overshoot. In other words the DE...
