Let's take a look at two screenshots with a Weighted Moving Average (WMA) plotted on a chart.
On the first screenshot you can find S&P 500 INDEX before noise is removed:
As you can see, it is difficult to identify a trend reversal (WMA intersects the price chart many times).
The Remove Noise functionality enables creating and analyzing
a smoothed curve of a price chart.

Take a look at S&P 500 INDEX after Noise Removal feature is applied:
A downtrend is easily seen now. There is a clear picture of a series of lower highs and lower lows (WMA does not intersect the price chart).

It is really important to eliminate deviations and outliers to be able to see real trends only.
