Failed to copy data from the indicator, error code 4806

[Hoàng Thị Lan]

I have been trying to work with error 4806 and I am a newbie I hope someone can help me to fix it

I declared the double indicator and in the compile they give absolutely no errors until I check the field value

int OnInit()
{
   MA_SET     MA_1 = { 34 };
   MA_SET     MA_2 = { 89 };
   MA_SET     MA_3 = { 200 };

         ArrayResize(STT_iMA,3,0);
         ST (STT_iMA[0],MA_1);
         ST (STT_iMA[1],MA_2);
         ST (STT_iMA[2],MA_3);  
}
//==================
double iRSIGet(const int handle, const int index) 
{
   double RSI[1];
   ResetLastError();
   if(CopyBuffer(handle, 0, index, 1, RSI) < 0) {
      PrintFormat("Failed to copy data from the iRSI indicator, error code %d", GetLastError());
      return(0.0);
   }
   return(RSI[0]);
}
//==================
double iMAGet(const int handle, const int index) 
{
   double MA[1];
   ResetLastError();
   if(CopyBuffer(handle, 0, index, 1, MA) < 0) {
      PrintFormat("Failed to copy data from the iMA indicator, error code %d", GetLastError());
      return(0.0);
   }
   return(MA[0]);
}
//==================
void S_13_Indicator()
  {
   handle_iMA =  iMA( Symbol() , PERIOD_M15, Period_iMA, 1,MODE_EMA,PRICE_CLOSE);
   handle_iRSI = iRSI( Symbol() , PERIOD_H1, 14 ,PRICE_CLOSE);
      Indi_iMA_15   = iMAGet  (handle_iMA,1) ;
      Indi_iRSI_H1  = iRSIGet (handle_iRSI,1);
  }

- Failed to copy data from the iRSI indicator, error code 4806 

- Failed to copy data from the iMA indicator, error code 4806

Can someone please help me figure out what I did wrong. Thanks

Thanks . i got what you mean, i worked with that but all my iMA value declarations and above are invalid

i used ArrayResize above, maybe I should change that to match

This change should fix the error code 4806 issue. If the error persists, double-check your handle initialization and make sure the timeframes and periods used for iMA and iRSI are appropriate for your strategy.
