How they are ranked

By the winner's closing price: the last price before the first bell, the best across the books we read. The chance shown is that price with the bookmaker's margin taken out.

02

What counts

Professional bouts with a price on both sides and a decided winner. Draws and no contests are left out; a disqualification counts as the result it was.
