RSI Custom Smoothing - indicator for MetaTrader 5

What is the purpose of the above updates: now, indicator levels and colors can be managed from within the Expert Advisor. This feature is especially useful during visual testing. For example, non-standard levels are set in the EA: 35 and 75. When using the RSI Custom Smoothing in the visual testing mode, the levels of 35 and 75 will be displayed on the chart.

Indicator buffer smoothing has been added. Smoothing is performed though a Simple averaging method with the period of 6.

An example of creating an indicator handle in the EA:

//--- create handle of the indicator iRSI
   handle_iCustom=iCustom(m_symbol.Name(),Period(),"RSI Custom Smoothing",Inp_RSI_Period,
                          Inp_RSI_Color,Inp_RSI_Width,Inp_RSI_Level1,Inp_RSI_Level2);
//--- if the handle is not created 
   if(handle_iCustom==INVALID_HANDLE)
     {
      //--- tell about the failure and output the error code 
      PrintFormat("Failed to create handle of the iRSI indicator for the symbol %s/%s, error code %d",
                  m_symbol.Name(),
                  EnumToString(Period()),
                  GetLastError());
      //--- the indicator is stopped early 
      return(INIT_FAILED);
     }
