There are 3 methods of Dutching shown here.
Each has its advantages over the others concerning odds input for
calculation, control of total stakes, and profit target.

Simple Dutching

Allows odds to be input in
any sequence

Stakes remain unaltered
throughout

There is no control of Total
Stakes.

Set Amount
(Stakes Limit) Dutching

The odds of ALL the
runners need to be input before calculations can be done

Stakes will adjust, if more selections are added.

There is total control of Total Stakes.

Dutching
to a
profit target

Maintains profit level
regardless of number of runners or odds.

As
the number of selections increases, all stakes are adjusted to maintain
the desired profit.

Total Stakes can spiral
alarmingly, especially if the odds are short.

Dutching to a Profit
Target
Win as much as you like !
Choose a profit target.
Bet up to 25 selections for an equal
profit whichever wins.

Dutching to a Set
Liability
Lay to your
comfort level.
Choose how much to lose if you hit a winner with your lays.
Lay 1 to 25 runners, but your liability will remain the same.

Dutching is a method of staking several
selections in the same race.
Stakes are calculated so that providing
you hit the winner, each selection returns the same profit.

Dutching can be a very effective way of
betting on a number of selections in order to show a profit, but whilst
increasing the number of selections obviously increases your chance of
hitting the winner, every additional selection also reduces your overall odds,
and reduces your profit.

If Laying, the opposite applies.
Whilst
increasing the number of selections obviously increases your chance of
hitting the winner, every additional selection also reduces your overall odds,
but increases your profit it you miss the winner, since all your Lays will
be successful.
Bookies, or Betfair traders who Lay bets, are in effect Dutching the
market.

The number of bets placed is only limited
by the odds of your selections.
Once the combined percentage of all the odds of your selections exceeds 100%, the
calculation for Dutching cannot work, and returns a loss on every
selection.
You cannot Dutch an over-round book to profit by Betting.
Your Betting book must be under-round.
You cannot Dutch an under-round book to profit by Laying.
Your Laying book must be over-round.
Click on the Lay Tab above for an explanation of an over-round,
under-round book.

Odds as a percentage.
To calculate the percentage of your odds, divide the decimal "Betfair"
odds into 100.
For example, we know that even money is a 50 - 50 chance, so evens should
equal 50%.
Decimal "Betfair" odds for even money is 2.0.
100 divided by 2 = 50%

1/1 is 2.0 in decimal odds, so
100 / 2 = 50%
3/1 is 4.0 in decimal odds, so 100 / 4 = 25%
4/1 is 5.0 in decimal odds, so 100 / 5 = 20%
9/1 is 10.0 decimal odds, so 100 / 10 = 10%

Those percentages added together =
105%. The book is 5% over-round.
Odds of 1/1, 3/1 and 4/1 would = 95%. That book would be 5%
under-round.

Simple
Dutching.
This is the most commonly used method of Dutching.
I would guess that most Layers use this method to Lay selections to a
profitable book, but the same calculation can be used to Dutch Bet a
market.
The advantages of this method are that

The math's involved are
very simple

Each stake remains the
same regardless of the odds of other runners.

If used to Bet, there is no control of Total
Stakes.
As we Bet more runners, our liabilities increase.
If used to Lay, the
increase of total Bet £ accepted becomes an asset, as the
liabilities on a winner are offset by successful Lays on other
runners.
As we Lay more runners, our liabilities decrease.
We stand to lose a smaller amount on any winner due
to successful Lays on additional losers.

Dutching Example Betting.
As an example, we can Dutch selections priced at 4.0, 5.0 and
10.0, (total 55%).
Stakes would be :-

Odds

Winnings minus
Losing stakes

Net

5.0

80 -

10.0

90 -

45

An equal profit will be shown providing the percentage of the combined odds of
your runners doesn't exceed 100%.
Above 100% will show an equal loss on all selections.
A big problem if Betting with Simple Dutching is that , our total stakes increase as
we add more selections, so our liabilities increase on any winner.
(We stand to lose a greater amount).
If we add further selections with odds of 10.0, our total stake
increases by £10, (100/10). With 2 selections priced 4.0, 5.0, our total stake stands at £45.
With 3 selections priced 4.0, 5.0, 10.0, our total stake increases to £55.
With 4 selections priced 4.0, 5.0, 10.0, 10.0, our total stake increases
to £65.
With 5 selections priced 4.0, 5.0, 10.0, 10.0, 10.0, our total stake
increases to £75.

The size of the increase is in proportion
to the size of the odds.
Short odds add large increases, and longer odds add smaller increases.
For instance odds of 2.0 adds £50, whilst 20.0 adds
£5.

If Laying using Simple Dutching, the
increase of total Bet £ accepted becomes an asset, as the
liabilities on a winner are offset by successful Lays on other
runners. (We stand to lose a smaller amount on any winner due to
successful Lays on losers).
If we don't hit the winner, our net profit is the total of the stakes we
have accepted.

Now if we Lay further selections with odds of 10.0,
our total
payout decreases by £10, since we would have additional successful Lays. With 2 selections priced 4.0, 5.0, our total bets accepted stand at £45.
With 3 selections priced 4.0, 5.0, 10.0, our total bets accepted increases
to £55.
With 4 selections priced 4.0, 5.0, 10.0, 10.0, our total bets accepted increases
to £65.
With 5 selections priced 4.0, 5.0, 10.0, 10.0, 10.0, our total bets
accepted increases to £75.

In each case, as more bets are accepted, we have more funds available to
pay out on a winner.
If we are able to Dutch a Lay market of more than 100%, we make a
guaranteed profit.

own book.
To sum up, as you Lay more runners your liabilities become less,
and the more you stand to make on a "Skinner" - any horse you haven't Layed.

Set
Amount (Stakes Limit) Dutching. Set Amount Dutching uses a different formula to control our total
stake to stop it spiralling as we add more selections.
In the simple Dutching example above, each
stake remains the same regardless of the odds of other runners.
With this Dutching formula, the stake on each runner decreases as
more runners are added.
In this way, the Total Stake remains constant.

This example uses a total stake of £100.

A winner at odds of 4.0 wins 3 x 45.45 = £136.35 less losers of £36.36
and £18.18 = a net profit of £81.81.

Before placing these bets, we could see
that we would be betting odds-on, since the percentage of the odds
combined exceeds 50% (evens).
Another indication is that our profit of £81.81 is less than our total stake of
£100.
If our percentage was less than 50%, our profit would be more than £100
and we
would be betting odds against.

Setting a stakes limit on your Dutching
is a very effective way of betting on more than one selection,
especially if you follow a staking plan.

Dutching (Laying) to a Liability
Target
This Dutching method
offers total control of your liabilities whilst you lay up to 25
runners.
Use this spreadsheet to lay up to 25 runners for a liability of your
choice if you hit a winner.

Dutching to a Liability target.

The stake on
each runner increases as more runners are Layed.
The total stake (your "Skinner" amount if you don't hit the winner) increases as more runners are added.

Desired liability remains constant.

This Lay staking method may be suitable
for use with a staking plan.

Lay big odds for small liabilities if you choose.

Limit the amount you lose if you Lay
the winner - in any sport.

As you lay more runners, your
liability remains at the level of your choice.

As you lay more runners, your Total
Stakes increase.
If you don't hit the winner with your lays, all
your lays are successful and you clean up with profit equal to the
total of all your lay stakes.

A problem with this
method of Lay Dutching is that the odds of all your selections need
to be put into the spreadsheet before you start to place your lays.
If you alter any of the odds or you add another runner, ALL the
stakes will change in order to maintain your liabilities at your
chosen level.

Problems. A problem with Dutching several runners is that placing a series of Bets or
Lays takes time.
During that time, the odds of your
selections often change.
You need to decide which Dutching method suits you best, a Set Amount for
your Total Stakes, uncontrolled Totals Stakes, or if you are laying,
total control of your liabilities.

If you are using the Simple Dutching method, time makes no difference since
your stakes remain the same regardless of the odds of other runners,
but you will have no control over increasing Total Stakes.
Simple Dutching is best suited to Laying in my opinion.

Dutching to a Profit Target could be used
as part of a staking plan.
This method is best suited to bigger priced selections, since short
prices can cause dramatic increases in stakes.

Minimize your Internet window and Excel window so that you
can see them together side by side.

Place all your bets so that you can see them all together -
Don't submit anything yet.

Adjust your spreadsheet and your bets to suit so that all
your bets carry the required stake at the current odds.

At the appropriate moment, submit the whole lot together,
and hopefully, you should get all matched in one go.

I know from experience that odd ones may not get matched due
to odds movements, but even using one touch software
submissions, it is difficult to get matched every time.

Lay and a Bet with a stake less than the £2 minimum For a bigger view of the videos below,
click the icon with 4
small arrows near the bottom right
hand corner, just below the " T " in the word "Tube"

Be careful.
Make sure you get the odds right.
There are plenty of sharks on Betfair waiting for
mistakes.
If you offer to Lay at 1000, instead of 1.01, and your
Betfair balance is big enough, your Lay could get matched and cost you a
packet.
You could be paying out at 1000/1, so my advice would be to raise your
initial liability which would raise your minimum stake on the
spreadsheet, or find another match / race, unless of course you are sure
of what you are doing when betting or laying at less than the minimum.
