OrderOpenTime function

With the help of the OrderOpenTime() function we can get the date and time of opening of an order/position selected previously by the OrderSelect() function.

   datetime OrderOpenTime()

• In case of a pending order the OrderOpenTime() function returns the date and time when the order was placed.
• In case of an open or closed position it returns the date and time when the position was open.

In order to determine that a position was open today we need to know the value of the type datetime for today’s date at 00:00:00 o’clock.

Four new functions will help us in this:

• datetime CurTime() — the time when the last quotation came in the form of the number of seconds passed after 00:00 January 1, 1970;
• int TimeHour(datetime time) — returns the order number of the hour for the time time;
• int TimeMinute(datetime time) — returns the order number of the minute for the time time;
• int TimeSeconds(datetime time) — returns the number of seconds from the beginning of the minute for the time time.

For example for 02:16:05 functions TimeHour, TimeMinute and TimeSeconds will return consequently 2, 16 and 5.

We remember that a value of the type datetime represents the number pf seconds passed since 00:00 1 January 1, 1970. Also we remember that there are 60×60 seconds in an hour, and 60 seconds in a minute. That’s why knowing the current time (we can get it with the help of CutTime), we can get the time of the current day for 00:00:00 o’clock:

   int c_time = CurTime();   
   datetime day_start;
   day_start=c_time-TimeHour(c_time)*60*60-TimeMinute(c_time)*60-TimeSeconds(c_time);

And the whole code which will count the profit on all closed positions that were opened today, will be as follows:

   //---- we will count the beginning of the day  - variable day_start
   int c_time = CurTime();   
   datetime day_start;
   day_start=c_time-TimeHour(c_time)*60*60-TimeMinute(c_time)*60-TimeSeconds(c_time);
   //---- we’ll count the profit
   int profit = 0;
   int pos;
   for ( pos = 0; pos=day_start) profit += OrderProfit();
             }
         }
       else
           Print("Error ", GetLastError(), " at selecting order ", OrderTicket());
     }
   Print("Total profit on all closed positions = ", profit);
