Simple code using SLEEP not working
Did you see about function Sleep() ?
The Sleep() function suspends execution of the current expert within the specified interval.
The Sleep() function cannot be called from custom indicators since they calculate in the interface
thread and may not decelerate it.
The checking of the expert stop flag status every 0.1 second has been built into the function.
In addition to it see article Testing Features and Limits in MetaTrader 4:

- Some functions are processed/passed without output
These are Sleep(), Alert(), SendMail(), PlaySound(), MessageBox(), WindowFind(), WindowHandle(), WindowIsVisible()

Thanks Rosh,
As i said i'm really a rookie...
Do you know other way to make it work?
What i really want is to be able to make the order at a specific time, i.e., 3 or 4 hours from the moment i initialize the script in the pair.
Thank you once more.
Seeing you are a rookie!

Hello everyone,
I'm new to mql4 and I've been trying to use this very simple code with no success.
The idea is to trade at specific time, puting the script into sleep for about 2 hours, and then making the order.
It works for 6 minutes, but does not for such time as 2 hours, i.e., after 2 hours it is removed (uninit reason 0).
Does anyone can help me, or have other idea to make it work?
Many thanks in advance.
int start()
{
if ((Hour()==10) && Minute()==00)
{
Sleep(7200000);
OrderSend(Symbol(),OP_BUY,0.01,Ask,3,Ask-50*Point,Ask+20*Point,"",0,Green);
}
}
