Betfair is the largest betting exchange in the world. Although you can trade on all manner of sports, here we focus on the
horse racing side of the Betfair empire. To find out more about what a betting exchange is visit our horse racing terms.
Personalised Betfair/Exchange Calculations
An extremely common request from our members was to show what the return would be if following a
horse racing system using a betting
exchange such as Betfair. In order to do this we investigated many different methods
of delivering this data - ultimately our research pointed to the clear facts there are so many opinions around, if we did
offer up a figure it was likely to upset someone. This is because of the nature of betting exchanges and how they operate with
the prices available to back/lay fluctuating dramatically dependent on movement in the market and several other factors.
Another option was to use the Betfair SP, but discussions both internally and with members led us again to the conclusion
this would not satisfy all with many finding the figures unsatisfactory for their purposes and the backdating of Betfair SP in line with
how far back our database goes would be nigh on impossible. Also the varying commission rates paid by members should be taken into account.
It seemed the only way to deliver an option to satisfy all was to offer the option for members to set their own figures.
To do so, we can use the SP (official starting price used as horse racing industry standard) and then deduct/add a
percentage dependent on the price range of the horse. For example if you believe horses at odds on
are approximately 5% better in price to back on Betfair, you can apply this setting appropriately.
