[amibroker] Re: Line color question

Trading Reference Links

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?

Steve
