Problem solving in programming

[niloufar mohamadi]

Hi Can someone please solve the following problem for me? :)

      string delay="00:10";
       datetime    time=(datetime)PositionGetInteger(POSITION_TIME)+StringToTime(delay);
       printf(" open order Position  "+(datetime)PositionGetInteger(POSITION_TIME));
       printf(" time : "+time );

output :

2013.12.28 08:27:52    Core 1    2013.09.04 13:58:40    time : 2057.05.08 13:10:00

2013.12.28 08:27:52    Core 1    2013.09.04 13:58:40    open order Position  2013.09.04 13:00:00

It looks like that the StringToTime() function doesn't accept the format of "00:10", you may check out the function's reference in the Documentation section.

If the "00:10" means 10 seconds, you may simply write the code as:

datetime time = (datetime)PositionGetInteger(POSITION_TIME)+(datetime)10;

thnx for relpay

It's because 

   string delay="00:10";

when converted to a datetime gives you :

2013.12.20 10:21:59.930    SomeTests (EURUSD,H1)    delay = 2013.12.20 00:10:00

Please read the documentation about StringToTime():

The function converts a string containing time or date in "yyyy.mm.dd [hh:mi]" format into datetime type.

So if you want absolutely to proceed this way, you have to use :

   string delay="1970.01.01 00:10";

"Time" can have 2 different meanings: position and duration.

StringToTime() accept a string that represent a position in time (a particular moment) and not a duration/delay.

datetime data-type store seconds, so if you want to add your delay to a date, first you need to have its value in seconds.

If you want to represent a delay with the format HH:MM (hours : minutes), you need to extract from it the minutes substring with StringSubstr()

then convert it to integer with StringToInteger(), convert to seconds and add this value to your POSITION_TIME.

Something like this: (simplified)

StringToInteger(StringSubstr("00:10",3,2))*60
