Roy:
I have one more question. I want to enter the start date
and stop date for these lines when I first initiate this
new indicator. How can I parse an input string of:
mmddyyyy
into three variables?
Thanks.
Bob

Bob
Here are some line plots that might help. One of these was writteen by Jose
Silva, one by myself, and the other possibly a combined effort - in short I
forget. If these don't suit your needs then you may be able to use some of
the ideas to create your own indicator.
I believe there are also dll versions around that are probably more
sophisticated. Someone may be kind enough to pass a dll on.
