The FIR (finite impulse response) Filters Of Price Change indicator calculates a smoothed-out value of the difference between close and open price based on the smoothing function selected by the user. By default, it calculates a simple moving average of this value. In the input parameters, you can also select a window function to be used for the smoothing: Triangle, Hamming, or Hann.

In addition to the smoothed-out value, this indicator also calculates its rate of change and displays it as a separate plot.
