Hey Joe-
Once you have a style that you like, right-click in the inner window that you like and select 'apply to all inner windows". Then all windows should look the same. After that, save your style as a template: FILE | SAVEAS | TEMPLATE and give the template a name. Next, select FILE | OPEN | OPTIONS | 'Open with template' and select your template; select a new security and open. Your smart chart will update automatically. You will have to manually do this for all of your existing securities to have your new template applied.
The alternative would be to delete existing smart charts, set your new template as the default and then as you opened future securities, your new template would be applied.
HTH,
