How To Limit Ea To Trade Only On Sunday

I know this is simple, but It doesnt work for me.....any suggestions!??
I tried if(Day()==0) return(1);

Thanks

You actually need to use DayOfWeek(), otherwise you're pulling from the month, not week

string Day;

if(TimeDayOfWeek(TimeCurrent()) == 0) Day = "Today is Sunday";

Thanks guys, I appreciate it!

You want:
if(TimeDayOfWeek(TimeLocal())==0){......}

if you dont use the local time your computer might not trade since come brokers (Like Alpari) are CET time and actually start trading at Monday at 0:00 - even though its still sunday in the USA.
