Hi Jayson,
No need to rub it in. Anthony F. has already pointed out my
stupidity :(
Seriously though, there was a huge lag yesterday before posts were
coming up so I guess you did not see my earlier admission of
dumbness.
I remember all sorts of variations like .EQ. for "equals" and I
always used to read := as "set to equal"
Very confusing for an amateur. I have never used Metastock but its
combination for "equals" seems easier to grasp.
Back to the topic. The formula now works and for those unfamiliar
with it and would like to read more, check out

Best regards,
Anthony
