Hi Graham,
That adds the very next bar's closing price to the output list. Not
the very last bar in the array.
Let's say I run a scan for 1/4/2005, what I would like to see is the
closing price on 2/10/2006.
So I need someway of identifying the last bar in the array I think.
And if it requires too much hassle or code, just let me know.
Dave
