This indicator is an example of smoothing the Momentum indicator timeseries by filtering high-order harmonics.

You can use this approach for smoothing the output of any indicator. The major advantage of this method is that it has practically zero latency.

Indicator input parameters:

input int   MomentumPeriod=14;
input ENUM_APPLIED_PRICE   MomentumPrice=PRICE_MEDIAN;
input uint N = 7;   // Series length
input uint SS = 20; // Smoothing coefficient
input int Shift=0;  // Horizontal indicator shift in bars

where:

• N — sets the series length (power of two);
• SS — smoothing coefficient in the resulting spectrum zeroes out frequencies exceeding the set value. SS cannot be greater than 2^N. If SS = 2^N, the Momentum series is repeated.

This indicator requires the following library: https://www.mql5.com/ru/code/7000.
