Exactly! This is why all of the solutions that have been suggested so
far won't work because I want to look at periods where the start and
end points are both in the past. Conceptually it's a very simple
thing, but programming it using AmiBroker is something else. I
thought about doing the same thing as you are considering, but HOLY
MACKERAL, what a headache! I cannot believe there isn't a quick and
dirty way to get what I want without a Cray computer and a PhD in
information technology. I just want to be able to specify a start and
end point for the regression and standard deviation calculations, but
from a calculation elsewhere in the code and not from manual input.
That doesn't seem like an impossible dream, but MAN what a hassle!
Using LastValue I can get this no problem. But I don't always want to
use the last value in the array and that's the problem I have. I'm
absolutely sure there is a simple answer to this and I'm just missing
it because my brain is so fried from thinking about it.

final solution array. I'm still thinking about it and am interested in
the topic. Hope you find a solution.
