The list
1. Betwatch
Betwatch records every price change at 44 books: live prices within seconds and pregame prices about once a minute at the big books. History goes back to April 2026 and finished games keep it. The line movement tracker page lists the games where the consensus has moved most since the open, and the live board charts each book's moves. It does not send alerts.
2. Linewhale
Linewhale says its Line History tracks 30 days of line movement across 100+ sportsbooks. Its Steam Moves tool, which tracks sharp line movement as it happens, is Premium.
3. Covers
Covers shows the opening odds beside the current ones and links a line movement view per game. It lists nine US books by default.
4. OddsTrader
OddsTrader labels the opener next to the current price on its boards. It describes where a market started and where it sits now, not a per-book timeline.
5. Odds Assist Pro
Odds Assist Pro lists Moving Lines among its tools behind a free signup. Its pages do not describe how the tool works or how far back it goes.
Questions
What is the best free line movement tracker?
For the most history across many books, Betwatch records every price change at 44 books back to April 2026 for free during its beta. Linewhale offers 30 days across 100+ books. Covers and OddsTrader are quicker open-versus-now checks.
How do I see which sportsbook moved a line first?
You need a tool that records each book's price over time, not only the consensus. Betwatch charts every book's moves for each game on its live board, and its research page measures which books lead line moves.
What is the opening line?
The first price recorded at each book for a market. Comparing it with the current price shows how far and which way the market has moved. Different sites use different books for the opener, so they can disagree.
What is reverse line movement?
Reverse line movement is a line moving toward the side that has fewer bets, which is often read as sharp money on that side. Tracking it needs both bet percentages and the line history.
Do I need an account to track line movement?
Betwatch's tracker page and team pages need no account; the per-book history of every game is on the live board, which needs a free account.
Try it
The Live Board is free with an account. Without one, you can still use the odds pages for every league, the team odds pages and the betting calculators.
