Hi, I Have written an EA which should generate alert as soon as time exceed the current sever time. My time zone differ from server time by 30 min so I have a condition like

 if (Cur_time >(Alert_Time_1 - 0.30))  Alert ()

But Instead of working on Alert time it executes on very next tick. Please show me the right way to use time function in attached EA.

  int    Cur_Hour=Hour();             // Server time in hours
   double Cur_Min =Minute();           // Server time in minutes
   double Cur_time=Cur_Hour + Cur_Min/100;  
  
As you are inputting time as a decimal, you need to divide the minutes by 100

Hi,

  Sorry to bother you again, but unfortunately I'm missing something. Lets say I want to generate an alert at 13:00  and server time is 12:25 so I added a server lag of 30 min but its still end of getting alert on wrong time.  Im posting a shorter version this time please correct it.

extern double Alert_Time_1 = 13.00;
input string MSG1 = "Hi, type you msg here";
bool   T1 = false;

//--------------------------------------------------------------- 2 --
int start()                            // Spec. start function
  {
  
  int server_lag = 30;
    if (TimeCurrent()+ server_lag/100 >=Alert_Time_1  && T1 == false)             // If the time for the event has come
  
   {
     Alert(MSG1);
     T1 = true;
   }

Why don't you trigger the alert based on your local time? TimeLocal()

Start() will only get called when a new tick comes in. If there is no tick, there is no check of your alert.

Try running your alert from OnTimer() with maybe a 1 second timer

Thanks Knave, I have no issue with TimeLocal() can you tell me what data type should I use before Alert_Time_1 to correctly execute the condition mentioned below


 if (TimeLocal() >=Alert_Time_1  )  
Alert ();


Also let say I want to execute an alert on Local pc time 19:30, should I write Alert_Time_1 = 19.30 or after converting the fractional part to 19 hr + 30/60 min = 19.5 ?
