Hi Graham,
THANK YOU SO MUCH! YOU ARE SOOO NICE!
Please excuse me if I ask some stupid questions.
What does the "1" in "Slope20 = ROC(ma(c,20),1);"
represent? And what about the "1.3" in "addcolumn(slo
pe20,"slope20,1.3);" represent? Are they always constants or
variables that can be changed according to different conditions? Do
they represent slopes or something? I need to know this in order to
put the right value there.
Robert.
