How it works

Betwatch records every price change at every sportsbook it tracks, from the opening line to the close. Open any game on the Live Board to see where the line opened and every tick since, charted per book, next to live scores and player props. The Movement Tracker lists steam moves, which book moved first in each one, and reverse line moves. Both are free during beta with an account.

What it covers

42 odds sources across 25 leagues: 27 sportsbooks, 9 prediction markets and exchanges and 6 pick'em apps. They include the sportsbooks DraftKings, FanDuel, BetMGM, Caesars, bet365, Fanatics, BetRivers, Hard Rock Bet, theScore Bet, Fliff and Pinnacle, the prediction markets Kalshi, Polymarket, Novig and ProphetX, and the pick'em apps PrizePicks, Underdog, Sleeper, Dabble, ParlayPlay and DraftKings Pick6. Moneylines, spreads, totals and player props. Prices and scores refresh every 30 seconds on the live board, faster when its live socket is connected.

How to read a line move

A line moves when a book changes its price, usually because money came in on one side or news changed the game: an injury, a lineup, the weather. The size of the move matters less than who moved and when. When a sharp book like Pinnacle moves first and the rest follow, the market is reacting to informed money. When one book sits off the consensus, that book is where the best price is, until it corrects.

Which books does the market actually follow? Betwatch measured it on two weeks of every price change at 23 books: which sportsbooks lead line moves.

The number you bet at matters too. Beating the closing line, getting a better price than the market settles on, is the most reliable sign a bettor has an edge over time, which is why the full history from open to close is worth having before you place a bet.
