How do I make the result of the formula 180 while accepting a difference of plus or minus 5 ???

If I make expert advisor with a special indicator How. I Can test the expert advisor without having the indicator in the files?. The means issue is if I share expert advisor with others. I have to share the file of the indicator too.
