Pre-race cross matching

[oddstrader]

TBH i just couldnt pinpoint any noticeable difference from my my side,

Hi
Strangely enough; I ran a BOT on the pre race today from a test account and it had a positive result. Looking at the P&L, XM doesn't seem to have caused any issues, in fact it may have assisted if anything.

I've heard mixed things from different quarters but most don't seem to have noticed much difference. In a bit of time I'll be able to give you a definitive answer on what impact it has had as we have been collecting data to see what behavioural changes it has had on the market.

[Euler]

Just analysing the first tranch of data and there are still quite a few markets where the book is going over broke. Not sure what this means or why this is happening. Should be nearly impossible if cross matching is on.

false starts ?

Rule 4's maybe, although you probably would have considered that. Maybe betfair's bot cant factor in 'dark liquidity' into its calculations

[Euler]

FYI, Was looking at the Aussie open final and noticed a 'this is a cross matching' market. On the rules tab.

Hi, I have seen one big difference so far.....the overs and under rounds have now finished pre race so my software is now scrap and my 15 - 20 K income has gone. If anyone comes up with a good work around I would like to know.....
Now going to cry in my beer, its like being made redundant!!!!!

TBH, I think this was Betfair's true intent with introducing this. As long as it result in a net gain to them. I don't buy the official rationale.

[dflowe]

Yep, I tend to agree with you, been getting some noise from them re the software for some time....
The20% tax was there first hit at me as a premium user
and I think they were very unhappy with the way I was"robbing them" I did the betfair trainers course and when the training team realised who I was they got a bit .....er....standoff ish....

Isn't the company that runs the XM called Betfair General Betting Limited who's main business is XM?

That companies profits from incorporation to 30 April 2008 was £272,497

To 30 April 2009 it was £1,253,140

It will be interesting to see 2010's and then 2011 when Horse Racing has been on for a full year......

Don't know if anyone spotted but on the 16:50 the book was overbroke constantly for around 2 mins. Very odd!

Just had a further thought about XM which I'm not sure has been addressed.

Pre-XM, if a massive lay spike appeared in a horse's chart, and it ran well below expectations, then eyebrows might be raised. But due to XM, surely it's unknowable (except by Betfair) whether someone was laying the horse in question or backing another horse. So do you guys think XM may encourage corruption?

Hi Jeff, Nice theory but I don't think so. If I lay one horse I effectively back another. XM or no XM, the net result is the same. Massive money to lay will see the price of a non wanted runner drift.

If you lay one horse, you back the field, not a particular horse, unless you're laying all the field except that horse (which I think is more or less what XM entails - and vice versa for backing).

But in the past, when there was a 10K lay spike for a horse, it was generally because a particular individual or organisation was heavily laying that horse, whereas now, it's not so clear why the spike occured...
