Terry, it works if indeed I reverse the plot order AND remove
StyleOwnScale from the indicator.
As it turns out however I still don't get the same scaling on the two
panes next to each other, of course because they have different
indicators and therefore different Auto Scaling levels. To finalize
I'll take the Max/Min of all combined indicators, add a few
%'s and use StyleNoDraw.
Thanks for your help!
