What is Cross-Matching?
Cross-matching is a more efficient method of matching bets on Betfair’s Exchange. Before Cross-matching, bets would only attempt to match other bet requests against unmatched bets of the opposing bet type (backs vs. lays) on the same runner in the same market.
On markets where cross-matching is offered, bet matching will attempt to match the bet request against opposing bets on the same selection and unmatched bets on other runners e.g. in a soccer match odds market the bet matching algorithm will attempt to match a back bet placed on the home team against unmatched lay bets on the home team or unmatched back bets on the away team and the draw. Customers will receive the best price available on the exchange at the time of bet placement.
