Indicator ADX in another timeframe

[Patoche90]

Good morning,

There is an error that I don't understand. Maybe I'm doing it wrong.

I would like to have an indicator that returns me ADX values in a larger unit of time.

 input int    PeriodADX= 14 ;
input int    ADXTrendLevel= 22 ;
input ENUM_TIMEFRAMES HTF = PERIOD_H1 ;
//---------------------------------------------------------------------
double       TrendBuffer[];
//---------------------------------------------------------------------
int          indicator_handle= 0 ;
int          indicator_Tempo= 0 ;
//---------------------------------------------------------------------
//      Initialization event handler:
//---------------------------------------------------------------------
int OnInit ()
  {
//      Displayed indicator buffer:
   SetIndexBuffer ( 0 ,TrendBuffer, INDICATOR_DATA );
   PlotIndexSetInteger ( 0 , PLOT_DRAW_BEGIN ,PeriodADX* 2 );
   PlotIndexSetString ( 0 , PLOT_LABEL , "ADXTrendDetector( " +( string )PeriodADX+ " )" );

//      Create external indicator handle for future reference to it:
   ResetLastError ();
   indicator_handle= iCustom ( Symbol (), PERIOD_CURRENT , "Examples\\ADX" ,PeriodADX);
   if (indicator_handle== INVALID_HANDLE )
     {
       Print ( "ADX initialization error, Code = " , GetLastError ());
       return (- 1 );   // return nonzero code - initialization was unsuccessful
     }
   indicator_Tempo= iADX ( Symbol (),HTF,PeriodADX);
   if (indicator_Tempo== INVALID_HANDLE )
     {
       Print ( "ADX initialization error, Code = " , GetLastError ());
       return (- 1 );   // return nonzero code - initialization was unsuccessful
     }
   return ( 0 );
  }

when I want to use indicatorTempo, it returns 0...

int TrendDetector(int _shift)
  {
   int      trend_direction=0;
   double   ADXBuffer[1];
   double   PlusDIBuffer[1];
   double   MinusDIBuffer[1];

//	Copy ADX indicator values to buffers:
/*
   CopyBuffer(indicator_handle,0,_shift,1,ADXBuffer);
   CopyBuffer(indicator_handle,1,_shift,1,PlusDIBuffer);
   CopyBuffer(indicator_handle,2,_shift,1,MinusDIBuffer);
*/   
   datetime timeArray[];
   CopyTime(_Symbol,PERIOD_CURRENT,_shift,1,timeArray);
   int maPosition = iBarShift(_Symbol,HTF,timeArray[0],false);
   
   // je récupere la date et heure -> variable maPosition : Ok
   // je veux ensuite récuperer l'état de l'indicateur à la période HTF pour la date donnée ? 
   CopyBuffer(indicator_Tempo,0,maPosition,1,ADXBuffer);
   CopyBuffer(indicator_Tempo,1,maPosition,1,PlusDIBuffer);
   CopyBuffer(indicator_Tempo,2,maPosition,1,MinusDIBuffer);   
   
//	If ADX value is considered (trend strength):
   if(ADXTrendLevel>0)
     {
      if(ADXBuffer[0]<ADXTrendLevel)
        {
         return(trend_direction);
        }
     }

//	Check +DI and -DI positions relative to each other:
   if(PlusDIBuffer[0]>MinusDIBuffer[0])
     {
      trend_direction=1;
     }
   else if(PlusDIBuffer[0]<MinusDIBuffer[0])
     {
      trend_direction=-1;
     }

   return(trend_direction);
  }

Here ADXBuffer[0] = 0 ...

I don't understand my mistake... Can you help me?

Thanks in advance.
