Help with this basic bit of code?

int a = 0;
   while(a<=100)
      {
      double r = High[a]-Low[a];
      r = r*10000;
      Alert(r);
      a = a+1;
      
      }

I'm currently trying to learn to code EA's and, as an exercise, I thought I'd create a basic script to tell me the range of the last 100 periods on a chart: int a = 0; while(a<=100) { double r = High[a]-Low[a]; r = r*10000; Alert(r); a = a+1; } Now, how can I modify this script to make it tell me the average range of the past 100 periods, rather than the individual range of each period? Thanks.

  int a = 1;
  double r =0;
  while(a<=100)
    {
    r += High[a]-Low[a];
    a = a+1;
      
    }
  
  r = r*10000;
  r = r/100;
  Alert(r);

double pips2dbl;

void BrokerDigitAdjust(string symbol) {
 int Multiplier = 1;
 int digits=MarketInfo(symbol,MODE_DIGITS);
 if (digits==3 || digits==5) Multiplier = 10;
 if (digits==6) Multiplier = 100;   
 if (digits==7) Multiplier = 1000;
 pips2dbl = Multiplier*MarketInfo(symbol,MODE_POINT);
 //Slippage=slippagepips*Multiplier;
}

r = r*10000;
r = r/100;

r = (r/pips2dbl)/100;

 Alert(r);

Alert("range of the last 100 bars = "+DoubleToStr(r,2)+" pips");

Thanks for all the help, guys! One other little question: Is it possible to use information taken from multiple currencies in an EA? At the moment, it seems to me that an EA can only be applied to a single currency pair at a time - limiting the ability for an EA to combine information from multiple markets.
