Rick, I just tried your suggestion without success. The problem is I sometimes want the horizontal line to be green (following a rising line) and sometimes red (following a falling line). The <= and >= only allows horizontals to be one color (the first specified).
What I'm after is something that says: "If HHV(C,99) increases, color green and keep green until it falls". Any further ideas?
