Initializing EA with Time?

Hi all. I am just starting to learn mql4. I want the ea I make to only work during certain times. I am struggling to get it right.
Here is my code:


extern datetime start_t = D'06:00';
extern datetime end_t = D'14:00';


int start()
{
if (TIME_MINUTES > start_t & TIME_MINUTES < end_t)
{
Print ("Trading Time");
return;
} // Exit from start()
}


Does this look right to anyone?
I think its working but I dont no how to check. Or is there a better way to do it?

you can determine the current hour of the day with TimeHour(TimeCurrent()) same for the current minute of the hour TimeMinute(TimeCurrent()). Both of these will return an integer that you can compare with to determine if the current time falls within your requirements.
