Bettors and modelers
A decade of sportsbook lines next to the games
Moneyline, spread and total from 4 to 12 books per regular-season game for 2013-14 to 2023-24, joined to the result and our ratings.
Odds history is scattered, rarely names the book, and does not come with the game attached.
A backtest needs the price you could have taken and what happened after, in one row.
What to build
Closing-line backtests
Pull a day's lines by book, with each game's result against the spread and total, and test a rule against the price you would have got.
Model against the market
Compare our Elo-based win chances with the implied probability in the line to find where they disagree.
Movement before tip-off
Daily snapshots of each posted line show where the market moved before a game.
What it will not do
- Before 2023-24 each book has one final pregame line, stored as the close; there is no opening line then.
- Since 2024-25 there is usually one book per game. Nothing before 2012-13.
- Women's college basketball has no odds tools.
