I
think Barsindex IS a number. It returns basically the same number as cum(1)
the difference being that barsindex is faster and one is zero
based..
Regards,
Jayson

Boolean question
Thanks Graham,
I'm slowly making my way through this. I don't
have to use an IF. And won't again.
Now it seems that barindex() is
not a number. As in Close[Barindex()-i]. Sure looks
like a number to me.
