Dear friend i am little confused how to coppy buffer of stochastic ?

//--- Copy the new values of our indicators to buffers (arrays) using the handle
   if(CopyBuffer(Stoch,0,2,Main)<0 || CopyBuffer(Stoch,1,2,Signal)<0)
      
     {
      Alert("Error copying Stochastic indicator Buffers - error:",GetLastError(),"!!");
      return;
     }

Please correct this for me,,

Thanks in a advance

What is Main, what is Signal ? CopyBuffer need 5 parameters.

How many data do you want to copy ? It's "amount" or instead "count".
