What comes to mind further is to make the 'Chg' related to the volatility of the 
security rather than keeping it constant at 2.5 or 5 or some other value.

One additional question. How do you get the display of the values of Sup/Res on the
Y-Axis, (23.25/19.63) in the chart below ? (I guess it's some setting.)

Actually what I was inquiring about was, if have some studies (say simple
trend-lines) drawn on my Price chart already, and then if I plot a different chart
with 'Sup/Res' study, then I don't see my earlier studies and 'Sup/Res' chart within
a single Price chart. Of course I'll be able to re-draw the trend-lines, but don't
want to re-draw them if I can avoid it. And it I've got EMAs, BBs also on the Price
chart, then re-doing it all will be a time-consuming task ...
