Newbie question RE datetime expiration

New comment
 

Hi,

Just a quick question, I am trying to add an expiration time on a buy script. I have added the line extern datetime Expiration = 0; to my script which is ok but is there a way i can make the order expire at 9.00pm on the day that the order was placed rather than having to manually input the date and time every time when i launch the script?


Thanks in advance guys any info would be greatly appreciated.

You compute 9PM
   #define HR2400 86400 // PERIOD_D1 * 60 = 24 * 3600
int    time(datetime when=0){
   return int((when == 0) ? TimeCurrent() : when) % HR2400;  }
datetime   date(datetime when=0){
   return ((when == 0) ? TimeCurrent() : when) - time(when); }
/////////
datetime bod = date();   // Midnight
#define HR2100 75600     // 9PM = 2100
datetime expiration = bod + HR2100;
 

Hi, Thanks for the reply.

You will have to forgive me as this is the first time i am trying to mess with scripting, I downloaded the following script and added the following line extern datetime Expiration = 0; this gave me the option to set an expiry for the order which i had to set manually each time when i ran the script

how would I add the code you gave me so it would have a default expiration time of 21.00?


thanks again!
