Calculating SMA for strategies

[andrew.potter77]

hello the Moving Average file includes this function:

double SimpleMA(const int position,const int period,const double &price[])

  {

//---

   double result=0.0;

//--- check position

   if(position>=period && period>0)

     {

      //--- calculate value

      for(int i=0;i<period;i++) result+=price[position-i];

      result/=period;

     }

//---

   return(result);

  } 

 

What price array should I pass to the function when calculating on a Symbol?  Thanks

Generaly,it should be close[].

thanks

I have had difficulty in passing the array. 

here is my code in the main program:

double close_fast[50],close_slow[100],close_veryslow[150];

 CopyClose(_Symbol,PERIOD_D1,0,FastEntry,close_fast);

  double FastEntryMA=SimpleMA(0, 50,close_fast);

the error i get is

double close_fast[50],close_slow[100],close_veryslow[150];

>>Modified to: 

double close_fast[],close_slow[],close_veryslow[];
