Hello,
Simply Use DayOfWeek() function:
http://www.amibroker.com/f?dayofweek
dw = DayOfWeek();
NewWeek = dw != Ref( dw, -1 );
NewYear = Year() != Ref( Year(), -1 );
WeekNumber = Sum( NewWeek, BarsSince( NewYear ) );
Best regards,
Tomasz Janeczko

Subject: [amibroker] WEEKLY function workaround
>A suggestion I made at the AmiBroker site recently was a "WEEK"
