Alert: Error copying Bollinger Bands indicator Buffers - error:4807!!

[Gouveiaa]

Hi, so i was about to test my EA and I had this error "Alert: Error copying Bollinger Bands indicator Buffers - error:4807!!" What am I doing wrong? I used the same code on my another EA and it worked.

Regards 

if(CopyBuffer(BolBandsHandle,0,0,3,BBMidle)<0)
   {
   Alert("Error copying Bollinger Bands indicator Buffers - error:",GetLastError(),"!!");
   return;
   
   } 
   
   if(CopyBuffer(BolBandsHandle,1,0,3,BBUp)<0)
   {
   Alert("Error copying Bollinger Bands indicator Buffers - error:",GetLastError(),"!!");
   return;
   
   }
   if(CopyBuffer(BolBandsHandle,2,0,3,BBLow)<0)
     {
      Alert("Error copying Bollinger Bands indicator Buffers - error:",GetLastError(),"!!");
      return;
     }

   if(CopyBuffer(maHandle,0,0,3,maVal)<0)
     {
      Alert("Error copying MA indicator buffer - error:",GetLastError());
      return;
     }

Anil Varma :

it does not explain what is WRONG INDICATOR HANDLE !!!

This means the following:

• You or did not create an indicator handle
• or you created an indicator handle and received an error (but did not handle the error)
