wiljons, why back Anderlecht at 12.5 when you can lay Munich at 1.09?

magician, I believe they nick the spread, see my example earlier

The implication here seems to be that betfair are operating a matching engine in some markets.

BF exists as I understand it as a person to person betting exchange . If Betfair themselves are operating in these markets then that obviously isn't person to person and Betfair are exploiting their position as the operator to profit from these markets.

Have they used the permission they received from the GC to operate in the exchange games markets as a precedent to do the same across the board? That would be a very worrying development. Playing poacher and gamekeeper at the same time gives them a wholly unfair advantage

Has anyone received any information from Betfair that they are not acting in this manner?

Teapot - you said earlier you tried to back Murray at 3.0 and betfair matched you at 1.48 on Duffy

So if iv got this right, lets say you put 10 at 3.0 on Murray

Gives a profit of 20

If betfair layed your 10 at 1.48 then it only cost them 9.60 to get you your potential 20 on Murray

Where does the 40p go?

"will they pass on best execution, or will they nick the spread, between request and execution price"

They pass on the best execution. If there is overage in either direction rather than leaving the bet in the market, if it can be partially matched on the opposite side of the book they match it.

mr chips2

I dont know what they are doing - i did not know they started doing it, and as yet I don not know if they are doing it on horses races or not

I suspect I know what they have implimented but lets wait and see....

Scrip seems to know, and I have asked - so might know something later tonight

but I SUSPECT

if a person asks to back a outcome at a price that is not available at the front of the cue (FOC) on the left hand side of the screen (LHSS)

but that request can be matched but laying all other outcome at the FOC on the RHSS, then they do so and match you back, against a combination of back against all other runners

that is what I SUSPECT

questions are

1) does client still get best execution
2) does the existing time priority of the orderbnook get preserved
3) tounge in cheek, does and owner that backs an opponent get in trouble for laying his own horse :o)



Betfair match that individuals by laying all other outcomes

The Magician, my post was in haste, i apologise.

Scripophilist, is it any wonder? All he's asking who is matching the bet if not betfair or an end-user, the answer surely isn't that hard.

In fact i've just asked the question myself.

the man marcus

glad you find me polite.... and hope my post ( which I was typing while you posted yours) relives any suspicion that I have anything to hide

miljons, I can't be sure that they matched me at 1.48 but it was the price that appeared on the screen after I placed my bet, if they did indeed match me at 1.48 then they didn't pass it on to me they must have kept it for themselves lol... anyway im guessing a bit here because Betfair haven't announced exactly what they do, I was just surprised to matched at all

Scrip

I have called betfair - and expect an answer shortly ( but is it working on the horses)

a) in the market
b) in the SP betting

I suspect it is as my algorythms detected a change roughly that date - but I untill tonight put it down to random fluctuations

if they can do this, I assume they are now using Project X software. which is good news for all.

but if this matching process is allowed then betfair should start offering

All-up betting
Betfair Scoop 6 etc etc

typical betfair response, they just told me theyd email me, which they still havnt

Isn't this somewhat reminiscent of what sporting options started doing.

I seem to remember that ended none too well.

Does this happen when BF becomes aware of the incoming order, or only when it hits the exchange screen?

Before it hits the exchange screen

So we've established the following:

someone/thing behind the scenes can see our bets before they hit the system, let's call it The Jolly Green Giants Matching Engine for this exercise

The Jolly Green Giant Matching Engine presumably is an instant operator, else his purpose is non-existant

so in summary, something behind the scenes sees the market before we do and can take the money instantly

very people to people betting and fair

and no 5 sec delay

to add to this, i was also told by my source that this was first implicated on Football match odds, and is liekly to be spread across the markets but not the ones with more than 4 outcomes

strange - reports where Project-X coudl handle this for 400 outcome events.... perhaps they are not using it yet..... mmmmm more questions than answers

but this is fun, a new challange, writing bots to deal with the impact of this change

I have noticed in in-running tennis over the last couple of weeks that I have fairly often been matched at exactly the price I had asked for despite no money being available at that price on a refresh just prior to my money hitting the market and no excess money being available after my matched bet. This would fit with my bet being matched via the price on the opposing player. My bet on these occasions is being matched at exactly the price I ask for which would seem to suggest that any overround goes straight to betfair's coffers. This was not happening back in January during the Australian open etc.
Surely it would be fairer to use the B.td.q system whereby available back money on a two outcome market automatically also appears as an available lay on the other side.

The Magician

surely it's not possible to write a bot that can see bets before they hit the system and then match them instantly on in-play markets?

Guys, I remember a thread from about 2 months ago, I asked "bot" if Betfair intends to implement cross market matching & automatic overrounds matching, does anybody remember what the thread title was or who the starter was so I can pull it off?

Scripophilist.

I thought that the matching engine they used to employ was discontinued in 2005 or thereabouts. Have you any information to the contrary?
