In Vim, the help says it all. So, :help :command-range gives the
following possibilities:
* both -range and -count omitted: a range can never be used
* -range : range allowed, default is current line (as in :s)
* -range=% : range allowed, default is whole file (as in :w)
* -range=N : count allowed in line number position, default N
* -count=N : count allowed either in line number position or as first
argument, defaults to N
So, IIUC, the answer is: "you can't" have a command where all three of
the following are valid and act in three different ways:
:MyUserCommand
:.,.MyUserCommand
:1,$MyUserCommand

Certain passages in several laws have always defied interpretation and
the most inexplicable must be a matter of opinion. A judge of the
Court of Session of Scotland has sent the editors of this book his
candidate which reads, "In the Nuts (unground), (other than ground
nuts) Order, the expression nuts shall have reference to such nuts,
other than ground nuts, as would but for this amending Order not
qualify as nuts (unground)(other than ground nuts) by reason of their
being nuts (unground)."
