Betdaq and Betfair Arbitrage

This was taken an hour ago from Wolverhampton’s 7:50pm Ladbrokes Poker Maiden Auction Stakes. dozens of opportunities for arbitrage on Betfair and Betdaq today. The example I show you here is the 7.50pm at Wolverhampton. Please look at Denton Diva. £6 available at 16 and £57 available at 15.5 to back on Betdaq so what the bot does is look for another opportunity in Betfair. Ahh, lovely, there’s £22 available to lay at 9.8 and £37 available at 10.

So fill or kill orders go in simultaneously on both exchanges. The bot sees what is matched and aims to balance for a risk free profit of £20. I’ve allowed for a commission of 5% in both exchanges. A yield of 2.85% in a second. And no risk – assuming you’re matched in both places. I’ll write more on this at another time. And if ever there was a good time to have an account with both Betdaq and Betfair it is now. But it will not last for long!

    Hello. Is there actually a bot for the above (Betdaq and Betfair Arbitrage), and if so, how does one obtain it. Thanks

  2. Man of Mystery says

    Hi Rab. There isn’t one commercially available because each API from Betdaq and Betfair specifically precludes such a trading application. You can’t feed both APIs in to one bot. But it is technically possible. Though the vendor would lose their authorisation currently in a New York minute if they did it.

    But then again a screen scraper not using the API couldn’t be stopped, perhaps. Watch this space. 😐

  3. Rab says

    Thanks Man of Mystery.

    Looking at that image, there has to be something wrong with the feeds, one of them must be delayed. No way are prices ever that far out of line. I’ve heard you mention betdaq/betfair arbing a few times but I’ve yet to see an arb.

  5. Man of Mystery says

    Hi George.

    Valid point. But as I was only watching it’s impossible for me to say definitively. But there have been many other such spreads. I doubt they are all lagging.

    Have a great weekend sir.

  6. George says

    ok, thank you.

    I’ve just looked through all of todays racing and didn’t spot a single arb. The closest I saw was back price being the same as lay price on just a couple of runners. Maybe a piece of software would find a pip here and there if it was constantly looking, but minus commission and occasional mess-ups it surely would be hard making money.

    Another thing that concerns me is what happens when there’s a NR. Your snapshot is still far too good to be true, had a NR just been removed / announced perhaps?

    Hello guys,

    we’ve started developing this software. Only one problem is that there exists time stamp that makes the whole bets not really sure. Second thing is that BetDaq doesn’t have such amount of betting volume as betfair.

    Cool thing would be for example betandwin + betfair but betandwin = flash – no chance of parsing the data.

    Any other ideas or betting exchanges with API?

  8. Peter Allan Roberts says

    The only bot you need is between your ears & fast fingers, two pc’s or split screen; I trade mainly football & devise dynamic spreadsheets. A model I use determines the true spread prices of any market and by checking both exchanges one can instantly see which exchange is out of sync which often leads to an arb.

    Today for instance the true price on overs in Morecombe V Preston was 1.7 ~ Betdaq had 1.98 on offer ~ Betfair was 1.63 to lay ~ of course I cleaned up so don’t anyone say they don’t exist. I gave the arb out on Twitter ~ greenday4u profile.

    Hi Guys, tried this with 2 instances of gruss software 1 for betfair 1 for betdaq and both feeding the same workbook and logging the results and I can say that for a 1 week run I recorded just the 1 arb of 1 tic, it was a worthwhile exercise learning all the sort routieens etc but not financially.

  10. bob says

    This is fascinating… i thought of combining bet angel for betfair and bet angel for betdaq, running them both simultaneously, linked to excel. it could be possible to feed both sets of data in and make a formula to place the bets in the event of an arb!
    This means there are 2 APIs so no rule is broken technically if I’m not mistaken. I am going to work on this.
    Even if arbs rarely occur, an automated solution means it’s not taking up my actual time….
    To me it’s worth trying to create this kind of setup just to see if there is potential – the slightest consistent profit would mean it could be tweeked and scaled up.
    Please let me know your views on this idea 😉
