hey ms leopard...... it would be nice if we had just a tad more flexibility in layout and template creation..... your request is a case in point.....
however, one 'roundabout' way to achieve your goal would be to create a layout.... first place your index as the top chart and second place your security in the lower ...... adjust their size, dates, and such.... then save that as a layout....
now just open the layout and change your securites in it.....
if you uncheck the option 'change all charts in layout' you can change the bottom chart and the index stays as is..... or if you want to change the index ,it will change and the lower chart remains as is.....
you can use the arrow keys to scroll to next security or just type symbol and hit enter.....h
