Alert Issue - Anyone Care To Take A Quick Look?

Hi everyone,

I've trying to code a simple indicator which Alerts when price reaches Yesterday's High and Low. The Alert works fine but the only problem is that I want it to stop alerting once it has alerted already. My indicator keep alerting until I manually remove it.

In the code I've created a "test" section, which is currently commented. This section can be used to create a temporary alert price to test the indicator, so we don't have to wait for the price to reach Yesterday High/Low.

I would appreciate your comments and suggestions

#property indicator_chart_window
   
double Day_Price[][6];
double SoundWhenPriceIsYesterdayHigh = 0;
double SoundWhenPriceIsYesterdayLow = 0;

double test = 0;
    
int init()
  {
return(0);
}
  
//-------------------------------------------------------- 
  
int deinit()
  {
 
ObjectDelete("SoundWhenPriceIsYesterdayHigh");  
ObjectDelete("SoundWhenPriceIsYesterdayLow");  

/*
ObjectDelete("test");
*/

return(0);
}

int start()
{

  ArrayCopyRates(Day_Price,(Symbol()), 1440);


   SoundWhenPriceIsYesterdayHigh = Day_Price[1][3];
   SoundWhenPriceIsYesterdayLow = Day_Price[1][2];
   
   
 if (SoundWhenPriceIsYesterdayHigh > 0)
   {
      ObjectCreate("SoundWhenPriceIsYesterdayHigh", OBJ_HLINE, 0, Time[0], SoundWhenPriceIsYesterdayHigh);
      ObjectSet("SoundWhenPriceIsYesterdayHigh", OBJPROP_STYLE, STYLE_SOLID);
