Change default line color and width on custom indicator

 

I'm using a Currency Strength Indicator showing 8 currencies. How can I change the USD default line color and width, so that it is saved? I can change it on a particular chart, but at next use, it changes back to the default value.

Edited to change currency pairs to currencies. Added details. Added file type.

USD color is Dark Blue, width 0. What I'd like: USD color Steel Blue, width 2. 

It is an EX4 file.
