With relative success I have been using the Dutch Betting method on my horse racing betting.
I was wondering if anyone out there has or would have an idea on how I could set this up on an excel spreadsheet.
I sometimes bet on up to 7 or 8 horses a race using the dutch method and roll over my losses into the next race so when I collect I win my target profit plus winning back what I had lost on earlier races.
Please Help me!!!

Go to the following site which has an an excel spreadsheet for dutch betting with a saver bet: http://vic-greyhounds.com. Go to the dropdown search box and click on Staking.
This is most likely not exactly what you want but the author of the site may be able to help you out.

G'day TajRossi75(what a great horse!),

One question: When you invest on 7 or 8 runners in a race, what is your anticipated percentage return on investment?
Is it a pre-determined amount or do you rely on the market to hopefully return a div in excess of your outlay.
Do you bet utilising Prepost prices or do you bet close to start-time. Also, do you bet race-to-race or only on selected races. For example, from my experience it is very hard to gain an edge in races with odds on favs or where the percentages are dominated by only a couple of runners.
As this is a strategy similar to one I am currently researching, I am interested to see what safeguards you have employed to ensure you do not risk your bank by having too many losing wagers.
If you don't have a sound strategy, I can assure you that this strategy is fraught with danger(remember, you are backing more losing runners than winners).
Therefore, you must wager on your runners in the appropriate amounts to at least recoup your outlay, if possible.
Do you bet fixed odds or tote divs?
I personally utilise the "overs" available in having accounts in the three mainland TAB's.
I invest on 6 horses per qualifying race so I don't necessarily invest on each race on the program. This is because I must have a potential "edge" of 15% when I invest as it offers a buffer for late shorteners.
I repeat, in this strategy, protection of capital is the primary objective.
It would also appear that by backing 7 or 8 runners per race you may be concentrating on long-shots. Also, the very fact that you are investing on so many runners can be quite an exhausting exercise in itself.
I hope that I haven't probed too intrusively with my questions but this is an interesting approach and it requires constant monitoring of fluctuations and other factors etc. If the necessary effort and concentration is put in, this approach offers the prospect of long-term returns.

Hi
I am also in Adelaide
I have re-designed the original Dutchbook and made a creditcard size laminated calculator so it can be done within seconds without needing anything else exept ofcourse selecting the horses.

Have a look at my post (My Dutching System 25/03/03). Does this do what you want?

Have a play and see what you think.

Good luck
