Help With Array

[Benjamin David Hardman]

Hello, I am working on being able to input an array of values into a moving average function to be able to create an MA of any set of data basically.

But before I get to that point, I am trying to improve my knowledge of arrays as I feel under-developed.

I am simply trying to put the Ask value into an array to be able to call the ask for the current candle and the ask for the previous candle, but both values are coming back as 0.

Here is the code:

void OnTick()
  {
   double data = NormalizeDouble(SymbolInfoDouble(Symbol(),SYMBOL_ASK),Digits());
   
   double array[];
   ArrayInitialize(array,0);
   ArraySetAsSeries(array,true);
   CopyBuffer(data, 0, 0, 10, array);
  
  
   Comment(DoubleToString(array[1],Digits()),"\n",
           DoubleToString(array[2],Digits()));
   
  }

 double array[];
   ArrayInitialize(array,0);

The array has no size yet, you can't initialize it.
