This indicator is an example of smoothing the DeMarker 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 uint DeMarkerPeriod=14;
input uint N = 7;   // Series length
input uint SS = 20; // Smoothing coefficient
input int Shift=0;  // Horizontal indicator shift in bars


  • 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 DeMarker series is repeated.

This indicator requires the following library:
