Odds are not static quotes — they are living prices, and they move for exactly two reasons: new information (injuries, lineups, weather, motivation news) and informed money forcing bookmakers to reprice. Watching how a line travels from open to close is watching the market think.
The key distinction is who moved it. A price shortened by a flood of recreational bets on a famous club is noise; a price shortened seconds after sharp books took large positions is signal. Soft bookmakers follow the sharp market with a delay — that lag is where most genuine value bets live and die, often within minutes.
A common myth deserves burying: "steam chasing" — blindly betting whatever moved — does not work at soft books, because by the time you see the move, the price you can still get has usually adjusted past the value point. Our own testing found line moves are predictable in direction more often than chance, but not by enough to clear the margin. Movement is context, not a strategy.
On TipsAudit, every value flag shows its lifecycle: the price when we flagged it, how the market moved afterwards, and where it closed. If the market moves towards our flag, the edge was real and CLV confirms it; if it moves against us, we publish that too.

New information or money has changed the market's estimate. A shortening price means the market now rates that outcome more likely. Where the line ends up — the close — is the most accurate estimate; the direction of the move tells you which early prices were wrong.
We could predict the direction of moves with some accuracy and still lost money: the edge was smaller than the margin, and the bookmakers had usually moved by the time a bet could be placed. Steam chasing is in our strategy graveyard for that reason.
