What is a closing line?
The last price a sportsbook posts before the game starts. It is the market's final answer, which is why bettors compare the price they got with it.
Why do bettors look at closing lines?
Because a bettor who keeps getting a better price than the close is beating the market. The measure is called closing line value, and the guide on this site shows how to work it out.
Which sportsbook's closing line should I use?
Many bettors use a sharp book such as Pinnacle, whose prices the rest of the market tends to follow, and some use the consensus across books. Betwatch keeps each book's closing line, so you can use either.
Do historical odds include player props?
On Betwatch, yes. It records player props and alternate lines as well as spreads, totals and moneylines.
