What is a closing line?

The closing line is the final odds available on a market just before kickoff. It is the market’s last and most informed price — every bet, lineup announcement and piece of news that arrived before the match is reflected in it.

What does it mean when the closing line is different from the opening line?

The gap between open and close is the market’s week of learning compressed into one number. A price that shortened from open to close means the market raised that outcome’s probability; a price that lengthened means it lowered it. The bigger the gap, the more the market changed its mind.

How do you convert decimal odds to implied probability?

Divide 1 by the decimal odds. Odds of 2.50 imply 1 / 2.50 = 40%. Note that a full market’s implied probabilities sum to slightly more than 100% — the excess is the bookmaker’s margin (vig).

Why use Pinnacle closing lines specifically?

Pinnacle takes the highest limits in the world and welcomes winning players, so its prices are shaped by the sharpest money in the market. Its closing line is widely treated as the cleanest available estimate of true match probabilities, which is why analysts benchmark against it.
