How To make this code to scan multi Pairs

[savio]

Hi Can any one help with this code to scan multi pairs as it shown in the code.

      string pairs[]={"AUDCAD","AUDCHF","AUDNZD","AUDJPY","AUDUSD"};
      int PairsToScan = 5;


      bool isNewH1() 
      {
         static datetime BarTime;
         if (BarTime==0) 
         
         
         {
         BarTime=iTime(NULL,PERIOD_H1,0);
         }
         //----
         bool res=false;
         if (BarTime!=iTime(NULL,PERIOD_H1,0)) 
         {
         BarTime=iTime(NULL,PERIOD_H1,0);
         res=true;
         }
         return(res);
      }


//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |
//+------------------------------------------------------------------+
int OnInit()
  {
 
    return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int start()
{

   for(int i=0;i<PairsToScan;i++)


      double H1_Open1  = iOpen(pairs[i],PERIOD_H1,1);
      double H1_Close1 = iClose(pairs[i],PERIOD_H1,1);

      double H1_CloseRed   = H1_Close1 < H1_Open1;
      double H1_CloseGreen = H1_Close1 > H1_Open1;
      
      
      if (isNewH1() && H1_CloseRed)
          Alert("H1 Close Red    "+ pairs[i],"   ", TimeToStr(CurTime(),TIME_DATE | TIME_MINUTES),"  ");

      if (isNewH1() && H1_CloseGreen)
          Alert("H1 Close Green    "+ pairs[i],"   ", TimeToStr(CurTime(),TIME_DATE | TIME_MINUTES),"  ");









   return(0);
}

You can think along these lines too:

for(int i=0;i<SymbolsTotal(1);i++)
  {
   Print("SYMBOL: ",SymbolName(i,1)," Found At: ",i);
   
   // Do Something...
  }

Then you can easily add symbols if need be and it solves post and prefix problems among brokers by using SymbolName(pos) if you plan is to create a market product the use of 

      string pairs[]={"AUDCAD","AUDCHF","AUDNZD","AUDJPY","AUDUSD"};

Can become problematic so know that there are better solutions available.

What do you mean by 'scan'? If you mean to perform a backtest in MT4 Strategy Tester,  it is not possible.

scan mean search for met condition and alert
