RE: [amibroker] Ref. specific data

["bluesinvestor" <investor@xxxx>]

Here is how I have done it:

Cum(1) will assign a number to each bar of the stock.

StartDay=10000*(YY-1900)+100*Mnth+DD; is the formula used for AFL DateNum().
(Change the YY/Mnth/DD for the date you want).

So StartDate=LastValue(ValueWhen(DateNum()==StartDay,Cum(1))); will give you
the bar number of the date in question.

Hope this helps,
Peter

Guys/Gals:

Is there a way to refrence specific data in AB? In other words if I
want the close on January 3rd to be refrenced to start my
calculation. I also need to use the specific date to make a
calculation. I actually want to calculate market days between
specific dates.

any help would be greatly appreciated!
