<span

<font size=3 color=black
face="Times New Roman">Gurus,
<font size=3 color=black
face="Times New Roman">Does anybody
know how to subtract between two horizontal study lines in AFL code? I have to
study lines that I move around to calculate entry and exit points. What I'd
like to do is to show that vertical distance between these two horizontal lines
in the interpretation window. Would one of you gurus please let me know how to
do this?
