Description
The Finite Impulse Response Filter (FIR) indicator is a symmetrically weighted filter.
The indicator calculates the result for fast components by smoothing the price using FIR and displays the difference between FIR and FastFIR. Similarly, the slow components are calculated by smoothing FastFIR using FIR and displaying the difference between FastFIR and SlowFIR.
In principle, the indicator shows the smoothing differences using the FIR filter.
In this version, the indicator shows price sentiment: bullish sentiment when both indicator components are above zero, and bearish sentiment when both indicator components are below zero.
