As far as I know a notification (SendNotification) doesn't ring.

Are you talking about an Alert ? A Sound ?

You have to use Time or Bar to stop repeat ringing

   static datetime pastime = time[0];
   if(pastime!=time[0])
     {
      // Add your code for Send Notification which will trigger only once when a new bar occurs
      pastime=time[0];
     }
   
//--- return value of prev_calculated for next call
   return(rates_total);
