EMA

Exponential Moving Average

Click here to read about Moving Averages.

Similar to the Simple Moving Average. The way in which the EMA differs, is that the present price(s) are given more significance than the past prices. The significance for each older datum point decreases exponentially. Consequently the EMA reacts quicker than the SMA to any change in the price. When looking at an upward trend, we see that the EMA shows the trend faster than a SMA.

Although this sounds good, remember that the EMA can sometimes be subject to false signals. As with the SMA you can adjust the number of periods, and offset the line by another number of periods.

Parameters: Period & Offset.
