Bob-
Sorry about the funny characters - they weren't there
when I typed the note - very strange to see them come
up now...(the funny "n" was supposed to be a minus
sign).
Anyway thanks alot for your help - You are very
generous with your time to this group - as are many
others. I am (obviously) still learning and
appreciate this.
By the way, I think a friend of mine, David Watts,
contacted you awhile back about a swing indicator I
was trying to get programmed. FYI, David is still
working on it although it still isn't finished --- he
thinks he is close, we are hopeful. We being the
collective me. Being in England is starting to affect
my brain.
