  • Hi everyone,

    Does anyone know what book % is needed to back dutch in different markets? Just having "less than 100%" does not work, here is why:

    Market #1
    Back £1.28 @ 7.8

    Market #2
    Back £8.68 @ 1.15

    The book percentage above is 99.77% which would be £0.02 profit in the same market, but because they are in different markets it is a £0.04 loss:

    LOSE: £1.28 @ 7.8 = -£1.28
    WIN: £8.68 @ 1.15 = £1.30 - commission = -£0.06
    TOTAL: -£1.28 + £1.30 - £0.06 = -£0.04

    So how do I know what book percentage I need to make a profit dutching different markets?

    Thanks,

    Whitey :)

  • hi
    the best way is to ADD the commission to the bets made, then you will make the profit.

  • Hi mcbee,

    How do you mean?

    Add 5% to what would have been staked?

    So £1.28 becomes £1.28 x 1.05 = £1.34 and £8.68 becomes £8.68 x 1.05 = £9.11

    Thanks,

    Whitey :)

  • Hi mcbee,

    That does not work, it just makes more of a loss because you are staking more money at the same book %.

    Do you have any other ideas?

    Thanks,

    Whitey :)

  • Hi Whitey,
    If I'm understanding correctly you are trying to dutch in two markets as being treated as one event. I fail to see the logic behind it.
    Each race is bet to a tad over a 100% Betfair market.
    In any case you are treading too close to the 100% line when you quote odds of
    7.80 and 1.15 (7.80 = 12.82%) (1.15 = 86.96%) total = 99.78% and no room for error and commission to be paid on top of that !!. Of course if they both win then happy days. I feel
    you are trying to obtain the impossible. Try dropping your total% to 80 or below.

  • Hi racepro,

    It would be impossible for them both to win. The outcome HAS to be one or the other.

    In the example there is a profit if it is in the same market, but in separate markets it doesn't work. So I want to know what book % it needs to be to make a profit using 2 markets.

    Thanks,

  • hi
    sorry, you are correct, my brain didn't work as it should.
    i have tried many combinations and it cannot be done due to the commission been taken.
    the only way that i can work out is to have 2 more conditions that check the dutched payout from each market is more than your minimum profit that you want.
    the triggers will only place a bet if both markets have a profit.

  • Hi,
    I didn't understand obviously.
    You were talking about two markets on the same race.
    From what I see the margins are too tight and no room for error even if
    you did find any kind of solution.

  • hi
    the answer is 98.70
    but the highest price market has to place the bet *1.02
    the lowest price market has to place the bet*.98
    so 7.8=1.28*1.02   and the 1.15=8.68*.98
    but in your case the prices need to be 8.6 and 1.15 or 7.8 and 1.17 or better.
    at the book% 98.70 there will be a profit on both markets.

  • Hi,
    The mathematics may be correct but is this practical ?

  • hi
    i think he is using soccer markets 0-0 and over 0.5
    so if the prices are correct you get a guaranteed return,small but any profit is good.
