Roy,
Thanks very much for your help. As with numerous times before,
you've come and saved the day. Your ValueWhen() suggestion works
like a charm. I did use the following earlier:
SUPPORT:=If(cond and cond=LastValue(cum(cond)), CLOSE, PREV);
However, the above still had the horizontal line at zero due to the
PREV initialization. Your ValueWhen() method eliminated that problem.
Thanks again,
-Alex

By counting these events using
