Cross Matching

[vilnius]

Is there an explanation in the user manual for this function?

If not can anyone explain in simple terms what it does and in what circumstances it might be utilised.

Cheers

Thanks Mark, I had seen this page but it still has not sunk in, i need a simple easy to understand explanation.

Can I play in two or more markets (on the same event) simultaneously then green up across all markets with one click?

An explanation in the user manual would be useful

Cheers

The only purpose of the cross matching feature is to display the same odds as the website. It does not mean that you can green up across multiple markets. Cross matching is nothing to do with multiple markets. It does not mean that Betting Assistant is calculating the green up stake in a different way, this has not changed.

Here is another explanation from Betfair.

The Betfair Sports Exchange tries to match bets against the bets placed by other users as well as equivalent bets where possible. These "virtual" bets follow the rules for cross-matching posted in the Betfair.com Forum. For example, if a customer backs Player A in a tennis match at odds of 2.0, the exchange matches any lay bet at odds of 2.0 or better on Player A. In addition, the exchange also calculates all possible matches that are equivalent to a lay bet on Player A. So, if a customer backs Player B at odds of 2.0 or better, the exchange matches it with the back bet on Player A.

The Betfair website calculates the possible virtual bets that the Betfair Sports Exchange creates and displays those bets as if they were placed by other customers normally. In other words, bets displayed on the Betfair website may be actual bets placed by customers, or virtual bets that the website knows the Betfair Sports Exchange will match due to the cross-matching rules.

At the present time, the API returns only actual bets in the getMarketPrices, getMarketPricesCompressed and getCompleteMarketPricesCompressed services. The API does not include the virtual bets that the Betfair Sports Exchange creates for cross-matching.

Here is an example market in Betting Assistant. The bottom image is with cross matching calculations enabled. The example is with "Highlight liquidity created by cross matching" ticked in grid preferences.

As you can clearly see normally you would only see lay odds of 1.79 for under 2.5 goals. You would see 1.76 on Betfair's website and would possibly question this as other users have. Betfair do not provide the odds of 1.76 through the API, we have had to calculate them. All the odds highlighted in yellow have been calculated and are visible on the Betfair website, but not normally through the API.
