A reader writes to ask:
Please-does anyone out there know how to end a manuscript for a short story or novel?
Do you skip a line and write -END- (margin left)
or THE END (Centered)
or...
I've seen both methods you mention, and in addition I know writers who always end their manuscripts with "###" or "-30-" centered. The simple fact, though, is that you don't have to do anything explicit to indicate the end of a manuscript. The fact that there are no more words or pages after a certain point should indicate the ending all on its own.
If you are truly afraid that someone reading your manuscript will reach the end and think there are pages missing, then either of the methods you cite would be fine. There's no standard method, so let your personal preference guide you.
But if someone reaching the end of your story doesn't realize they've reached the end, then you probably have a big problem with the story itself, not with the presentation of your manuscript.
