Works fine for me.
When you are attempting to set these books up and you are looking at a profit target of say $20 have you ensured that you have got the book over 100% and there is an overround present?
What I suggest you do is google some articles on the art of bookmaking.

Faults with Bookmakng / Dutching tabs
Not exactly. You need the book to be over 100%, so you may be able to leave out the occasional long shot (aka a "skinner").demmas wrote:You must select all of the rows, is practically a LAY THE FIELD. I hope not to say inaccurate things.
But generally you will need all the runners.

Polite question:
I have just tried to make a Book from the Bookmaker tab by selecting all the horses to Lay and then set the Staking method to "Lay for a target profit of... 30". Why is the amount to bet on each horse 0.00?
If I choose either of the other two staking methods then varying amounts will be bet on each horse.
I have also tried this with some of the horses de-selected (same results).
cause your offering to lay all runners at prices that
add up to less than 100%. by asking ba to lay for a target profit of £30 it is not possible at the prices you are offering; it is saying to you THIS IS NOT POSSIBLE -hence individual stakes are 0.00 and total stake is 0.00
below is a screen shot for ascot 13:15 laying for a profit of £30 at the current lay odds available - as you can see at those odds you would be laying into a 99% book - cant be done by using the current lay odds they are under %100. you need to adjust your book so that you are offering prices that add up to a book of over 100%.

You do not have the required permissions to view the files attached to this post.
if you was to adjust the first 3 each 1 tick lower you would achieve a overround of 100.4%. ba would then be able to offer up your book.
fav 2.3 adjust to 2.28
2nd 3.15 to 3.1
3rd 4.3 to 4.2
4th stays at 200
but you would need stakes of 3 grand plus, 2 grand plus, 1500 plus and £35 respectively - total stake of over 7 grand - not really worth the risk.
you would be better off to stake to a more realistic liability, and after "each" book is matched so to speak, churn it over, and hope that no shorties get withdrawn.

It's because you are creating a partial book. With a normal trade you back and lay or vice versa so you hedge on that but when creating a book that's not applicable as it could create a really wild position. So we mark is as n/a by default to stop people getting into that mess accidentally. But you can remove the restriction if you wish.
