Global variables defined withing a function are scoped to that
function and all the sub functions within that function. But once
you call outside that function the variable is not available. If you
want the variable to be global it has to be in a global scope,
outside of the functions that will use it. Declare it at the top of
your code and it will have global scope as you mentioned. Otherwise
pass it as a parameter. This is much safer. You have to be careful
when using globals because anyone can change a global anytime and
anywhere, darn hard to debug if that happens. If that is OK then
make it global.
I would have to look at your code to see what you are doing.

of the indicator and was available to some others where the
indicator was used multiple times in same instance, but on different
panes.
