what trade more than one time

[[Deleted]]

Hi all,

 

This is the simple program i write, but it will give more than one alert in one time.

 

can some one help on that, how to make it give only one alert each time.

 

Thank you

 

 

 datetime  TimeCurrent();

 datetime b= D'13:59:00';

 datetime a= D'13:59:30';

  int abc =1;

  int bcd =2;

int start()                                // Special function start() 

 {

if( b == TimeCurrent()&&j<1)

{

 Alert(abc);

} 

if( a == TimeCurrent())

{

Alert(bcd);

}

return;                                 // Exit start()  

}

2.  datetime b= D'13:59:00';
    datetime a= D'13:59:30';

   These are 1:59 PM of the date you compiled the code. Don't expect more than two alerts ever.

   #define HR2400 (PERIOD_D1 * 60)  // 86400 = 24 * 3600
   int      TimeOfDay(datetime when=0){      if(when == 0)  when = TimeCurrent();
                                             return( when % HR2400 );            }
   datetime DateOfDay(datetime when=0){      if(when == 0)  when = TimeCurrent();
                                             return( when - TimeOfDay(when) );   }
   datetime Tomorrow( datetime when=0){      if(when == 0)  when = TimeCurrent();
                                             return(DateOfDay(when) + HR2400);   }
   //datetime Yesterday(datetime when=0){      if(when == 0)  when = TimeCurrent();
   //   int iD1 = iBarShift(NULL, PERIOD_D1, DateOfDay(when) - 1);
   //                                       return( iTime(NULL, PERIOD_D1, iD1) ); }
   
   OnIinit(){
      #define HR1359 49800     // (13*60+59)*60
      a = Tomorrow() + HR1359; // 13:59:00
      b = a + 30;              // 13:59:30

3. if( a == TimeCurrent())

   This matches only if a tick occurred on the exact second. One second later - no alert. Multiple ticks that second, multiple alerts.
   

4. redwind: can some one help on that, how to make it give only one alert each time.
   

   if( a != 0 && a <= TimeCurrent()){
      Alert(bcd);
      a = 0; // Suppress additional alerts

   if(a <= TimeCurrent()){
      Alert(bcd); #define HR2400 86400 // 24 * 60 * 60
      a += HR2400; // Next alert is tomorrow
