There are no indicators that show that a person is moving (or for any other external event). There are, however, various transits that may coincide with the desire to move. Quite commonly transiting Mars conjoining, squaring or opposing its natal place will find us dissatisfied with some element of our daily routine, and we might find ourselves rearranging the furniture, changing an habitual route to work, or shift, or the grocery store or bank that we shop and bank at. Relationships can begin or end. Or we might decide to move from one apartment to another one. It's the decision, not the actual move, that will coincide with the Mars transit. Sometimes a major move, to a different part of the country, will coincide with a career or identity change, timed by Saturn conjoining, squaring or opposing the Nonagesimal (90° above the Asc) or Sun, enabling you to establish a new identity among people who don't know you by the old one. Uranus squaring or opposing natal Uranus, indicating a new kind of career or calling, might during an appropriate Saturn transit within the (approximately) three-year period of the Uranus transit result in a move. There are, in short, lots of reasons for moves. There is no one reason, and therefore no one transit, that by itself is associated with moving per se. If it's only a move, if you're just not satisfied with the place you're at, Mars transits will be relevant. If the move is part of a larger change in your life Mars will still be relevant to the timing of specific decisions, but each decision/change will be an episode within a larger overall shift, and therefore will be falling within the longer period of a more gradual planetary transit/transition.
