Hi,

Upon request, I had recently submitted an exploration output of those 
same calculations (as opposed to the graphics). After reading that, 
progster posted a modification which I believe used the end of month 
calculations the way you might expect.

See post http://finance.groups.yahoo.com/group/amibroker/message/125857
