need help with expiration and timing code

i want EA set pending order expiration = "good till today"

can someone show me how??



below is formula i apply on ordersend() 's expiration function.

expiration=TimeCurrent()+(Period()*60)

the problem is the EA dont delete order on next day 00.00.00 time,and sometime will "overtime" due to traffic jam and order open at friday.



i found another formula D' 00.00.00'
but i dont know how to use





one more ,how can i apply expiration to orderdelete()???


if(TimeCurrent()+(Period()*60))
{
OrderDelete(OrderTicket());
return(0);

when i compile,an error 'TimeCurrent' - comparison expression expected appear.
