i-SpectrAnalysis_RSI - indicator for MetaTrader 5

The indicator exemplifies smoothing of price time series of the RSI indicator 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 uint                 RSIPeriod=14;
input ENUM_APPLIED_PRICE   RSIPrice=PRICE_CLOSE;
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. RSI series fully repeats itself if SS = 2^N.
  

dt_FFT library is required for the indicator operation.
