Making an indicator see the higher timeframe

 

I am editing the MQL5 downloadable indicator " MACD.mq5 " to make it show the higher time frame MACD instead of the current one, but with no success.

the main code I inserted is:

input bool FractalTime = true;                  // Fractal Application
//...
//...
//--- Get the proper timeframe depening on user requirement: 
ENUM_TIMEFRAMES T = 0;           
if (FractalTime==false) T = 0;
if (FractalTime==true)  T = PERIOD_M15; 

//--- get MA handles
ExtFastMaHandle=iMA(NULL,T,InpFastEMA,0,MODE_EMA,InpAppliedPrice);
ExtSlowMaHandle=iMA(NULL,T,InpSlowEMA,0,MODE_EMA,InpAppliedPrice);
//--- initialization done

However I am getting errors about:

Not all data of ExtFastMaHandle is calculated (100015bars ). Error4806


The full listing of the edited code is as follows:
