The indicator is an example of smoothing a time series of the RVI indicator by filtering harmonics of higher order.

This approach can be applied to smooth the values of any indicators. The main advantage of the method is virtually no delay.

Indicator input parameters:

//+----------------------------------------------+ 
//| Indicator input parameters                   | 
//+----------------------------------------------+ 
input uint RVIPeriod=14;                          // averaging period 
input uint N = 7;                                 // number Length 
input uint SS = 20;                               // smoothing factor 
input int Shift=0;                                // The shift indicator in the horizontal bars

where:

N — series length (power of two);
SS — Smoothing coefficient, zeroes the frequencies above the specified value in the obtained spectrum. SS cannot be greater than 2^N. If SS = 2^N, the RVI series is fully repeated.

The indicator operation requires the library: https://www.mql5.com/en/code/7000.
