如何在自定义指标中使用OnCalculate（）函数在MQL5 / OpenCL中使用GPU？

我使用MQL5创建了一个指标 .

在分析之后，我读到的程序是我的 OnCalculate() 使用了99％的CPU .

这是我的功能：

int OnCalculate( const int     rates_total,
                 const int     prev_calculated,
                 const int     begin,
                 const double &price[]
                 )
  {
//--- check for bars count
      float tempprice[];
      ArrayResize( tempprice, ArraySize( price ) );
      if (  rates_total <  InpMAPeriod - 1 + begin ) return( 0 ); // not enough bars for calculation
//--- first calculation or number of bars was changed
      if (  prev_calculated == 0 ) ArrayInitialize( ExtLineBuffer, 0 );

      ArrayCopy( tempprice, price );
//--- sets first bar from what index will be draw
      PlotIndexSetInteger( 0, PLOT_DRAW_BEGIN, InpMAPeriod - 1 + begin );

      switch( InpMAMethod )
      {
         case MODE_EMA:  Execute_Me( price,
                                    "CalculateEMA",
                                     rates_total,
                                     prev_calculated,
                                     begin
                                     );
                         break;
         case MODE_LWMA: Execute_Me( price,
                                    "CalculateLWMA",
                                     rates_total,
                                     prev_calculated,
                                     begin
                                     );
                         break;
         case MODE_SMMA: Execute_Me( price,
                                    "CalculateSmoothedMA",
                                     rates_total,
                                     prev_calculated,
                                     begin
                                     );
                         break;
         case MODE_SMA:  Execute_Me( price,
                                    "CalculateSimpleMA",
                                     rates_total,
                                     prev_calculated,
                                     begin
                                     );
                         break;
     }
     return( rates_total );
  }

以下是分析的结果：

请允许我告诉我，如何让 OnCalculate() 在GPU而不是CPU上工作 .
