hello everybody, 

I want to programm an EA, that opens at a certain time (which the user can define) pending orders and I have problems with this date and time functions like TimeCurrent().

Until now I have this: 

extern datetime time = D'2014.08.15 11:10:00'; 

and now I want to compare this time with the TimeCurrent() to open a pending order. The Question is: what argument should I put in the bracket? I don't really understand the definition in the documentary

https://docs.mql4.com/dateandtime/timecurrent 

 

The next question I have is: Is there the possibility to 'do math' with this datetime. For example if I have again the time defined like above, how can I define NewTime=time +3minutes ??

It would be very helpfull if somebody can answer. Thanks a lot

You need to understand what a datetime  (<---- link, please click me  ) type variable is . . .  ". . .   as the number of seconds elapsed since January 01, 1970"

 

If you want the datetime 3 minutes from now . . . TimeCurrent() + 3 * PERIOD_M1 * 60

  1. What bracket?
  2. Like this
    #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) ); }

thanks a lot guys, now I know how to do it. With the bracket I meant the one after TimeCurrent(). But it's the same think as in Symbol(), doesn't need any input arguments.

whish you a nice weekend
