Does the UMA have a feature to filter out spikes?

The Alpha Trader UMA by virtue of being a moving average will absorb spikes however if the spike is so large or there is for an example a large gap the data series can be skewed by that data event. The effect will be seen in the plot from smooth to a larger move - if for example the close does not come back within line of the prior closes before the spike or gap - this can cause a choppy line instead of normal smooth. A ma smaller period will show more chop and a larger period will show less chop and react less to spikes and provide a smoother line but will lag more on reversals. Also the type of data series you are using will also smooth out spikes or show them - for example 30minute versus a range 10 or tick 150.
