Indicator alert in every 3 seconds

[Saravanakumar D]

Dear Friends and Traders.. I've doubt in my Price alert indicator. It alerts on every incoming tick.. but i like to get alert on every 3 seconds..

the every incoming tick alert is annoying. Please guide me..

   static datetime NextAlert = 0;
   if(TimeCurrent() >= NextAlert && ... // logic to trigger alert
     {
      Alert(....);
      NextAlert=TimeCurrent()+3;      
     }

or

void OnTimer()
  {
   Alert(....);
  }

void OnTick()
  {
   if(.... // logic to trigger alert
     {
      EventSetTimer(3);
      OnTimer();
     }
   else
     {
      EventKillTimer();
     }
