Once the template is loaded, open the symbol changer settings and press okay.
It does not work until you do this.

Make sure to add the instruments you want(without a template attached so you can save resources).
Then "hide all" on your market watch. Now you will see your list of instruments on the symbol changer.

You can add the instruments manually in the settings if you want. This way you may not need any other charts open(I have not tried yet).

"TMA Market Info" indicator may need its y coordinates changed so it is not stuck over your RSI info etc.

These were the only hiccups I ran into when loading this all onto a new terminal.

Message me if you need any help setting up :)
