i-SpectrAnalysis – indicator MetaTrader 5

The indicator exemplifies smoothing of price time series by means of filtration of harmonics of a greater order.

This approach can be applied for smoothening any indicators’ values.

The main advantage of the method is a real absence of a delay.

Indicator input parameters:

//+-----------------------------------+
//| Input parameters of the indicator |
//+-----------------------------------+
input uint N = 7;     // Series length
input uint SS = 20;   // Smoothing coefficient
input int Shift=0;    // Horizontal shift of the indicator in bars

where:

• N specifies series length (power of two);
• SS – A smoothening coefficient in the resulting spectrum zeroes out frequency ratios exceeding set value. SS cannot exceed 2^N. Close series fully repeats itself if SS = 2^N.
  

library is required for the indicator operation..

This indicator was first implemented in MQL4 and published in CodeBase on November 23, 2006.
