IR Cross Matching bot - How does it work?

Very good point!

My understanding is that the cross-matcher is supposed to give best execution, which is clearly not the case here.

Surely the 21 was matched as the 29 appeared ie it took all prices on the way up and nothing was matched at less than 29 afterwards?

The 21 was matched well after the 29.00 went up.  There is no doubt about that.  The times can be cross referenced against several sources, the declared fact that the 29.00 went up about a minute into the race, and the fact the times given by Betfair for the matches at 29.00 are after the Youtube video (which starts at about 14:04:18) shows the 29.00 was up there.

Always thought it was 1.01 the OP worked for Betfair.  However, if the cross matching bot really is jumping down to below the highest available price, skimming off more money for Betfair, that would be a major scandal.

It's hard to think of an explanation - other than the cross matcher is not providing best execution.

You're right ballabriggs - failing any other explanation this is a real scandal in the making.

in e-mails betfair have sent to customers who had bets voided in the race it says bets were matched at 21 but when I checked my account today it says bet matched at 29.I dont know if the e-mail is incorrect or if they have changed these bets at a later date.

I have received an e-mail at 3-03 from betfair saying customers will be informed shortly regarding this matter......

I DONT KNOW FOR SURE....

but suspect that the voiding email is displaying the price they asked for on thier bet not the matched price...

probably just as simple as that....



Other explinations for this are very complex - so until it is show that these where MATCHED prices and not REQUESTED prices...

I would not run away with ideas....

if these bets are MATCHED PRICES and not fabricated then, there is a issue to look at

so the guy was not really matched at 21.... but 29

the email is misleading... nothing more sinister ( I assume)

To the Magician's point - do you remember how you placed the bet?  Did you request a lower price?

OK in that case if 21 was genuinely being matched with 29 showing then BF and their in-running matcher have got some serious questions to answer as an aside to the main case.

seems a mislabelled email.... not a incorrectly matched bet....

as if they dont have enough problems, they could get thier email eaders correct.... FFS

but myth debunked...

If the OP does indeed work for Betfair, this does seem a particularly bizarre thread to start.

Someone posted this on hrse racing forum shortly after the race , so I guess those prices showing must have been the asking price while the matched price was 29 :
