Presumably most punters will have noticed it by now. It started a couple of days ago, and operates in markets where it can instantly place an inverse bet. So for example, all the overs/unders markets in football. If you place a lay of over 2.5 goals at odds 1.5 for £100, the bot will instantly place a back of under 2.5 goals at odds 3.0 for £50, i.e. exactly the same bet. If you try to take some of its offer, it will instantly take the same amount of yours, resulting in a neutral position, so although it's easy to coax the bot to place bad value offers, you won't beat it, it's too quick.

It gets more interesting in-play when doing the same as above, because the bot's bet is not subject to the in-play delay, it appears instantly as soon as your bet hits the market.

The positives are that it is doubling liquidity, but should it be allowed to beat the in-play delay? What do you guys make of it?

Erm. There's a reason why the bot "beats" the in-play delay.

It's the Betfair cross-matching bot. It is just showing the equivalent of your bet on the other selection. The reason your initial bet get instantly matched if you try to take this "new" bet is that you are matching your own bet. It's like a bird who looks in a mirror and thinks he's seeing another bird. It was you all along. :-)

betfair cross matcher which skims money when someone bets on it and not the original bet.

It appeared this week, it's not the old cross matcher bot, it places bets more so than matches them. It replicates every bet and amount placed.

I just find it strange that nobody minds it being able to beat the in-play delays that we're all subject to.

It's just the inverse of your bet.  By displaying it on both outcomes, it improves your chances of getting matched.  **** displays your bets on both sides of the screen too.

It's doing the same job as the crossmatching bot. It's more of an algorithm than a bot really.

Trevh is right, I've noticed it too in the last few days. It would have to be Betfair doing it right? Surely nobody else is able to develop a bot that isn't subject to the in-play delay...

Because it's not a bot. If Betfair had promoted this better there would be far less angst about it. It's an algorithm to increase liquidity. Everyone complains about falling liquidity yet Betfair create ways of increasing it by getting more money matched and creating fairer markets and yet people still complain.

Schnyder's description was far more eloquent.

Are you referring to the cross-matching? That's been around for a long time. Think we're talking about something different...
Report Darlo Bantam November 9, 2014 12:33 AM GMT
It's doing the same as crossmatching but doing so across different but linked markets, e.g. O2.5 goals and 3+ goals, or match odds and the AH.

Yes don't have a problem with the cross-matching concepts, but I've been noticing some strange things happening last few days, I'm sure of which aren't related to the cross matching. I'm going to take a closer look at some in-play markets today to work out exactly what's going on

Well it started on Weds (poss Thurs) of this week, where as cross matching has been around for years?

So if it's replicating my bet, who is putting the money up, or is it spoof money? If I place a lay of over 2.5 at 2.0 for £100, it will place a back of under 2.5 at evens for £100. Can only £100 be matched then? Or can someone match my lay and match the bots back at the same time?

If it disappears and is not actually available liquidity, what is the point of it? It would be no more than spoof money in that case. I.e. someone tries to take the available £200 showing, but only £100 is actually available to match? How is that boosting liquidity?

The "bot" is replicating your money so it's more likely to be matched somewhere.

Your example above - before cross-matching - two people asking for the same thing but on different sides of the market wouldn't have been matched despite the fact they were on opposite sides of the same bet.

As far as I read, the new crossmatching across markets, is doing the same kind of thing. It's boosting liquidity because it's money that wouldn't have previously been matched despite the fact they were asking for other sides of the same bet.

Forget thinking of it as a bot, and simply a way of matching money - the same as one person backing something at evens, is matched against someone laying something at evens.

Um, this has been happening for years. Is that not what the cross-matching bot is? Maybe they've expanded into some new markets as part of them venturing into cross market cross matching.

If someone backs the £100 at over 2.5 then the £100 at unders is just reduced. If someone matches the unders then Betfair will match the equivalent of your bet.
