Back Dutching
« on: 23 Apr 2014, 10:27 »
Just wondering how it would be possible to put a limit on my back dutching so that it will not bet on situations where my potential profit is less than say 20% of my potential loss.

hi
you would need a condition to calculate the dutch profit and loss.
to do that you need to know how many selections are been dutched

You can use this trigger condition:

Selection's Trigger Expression (100 - match_b_book)/match_b_book is equal or greater than P/100

Where P is the percentage, i.e. 20.

FYI:

liability = (ATW*match_b_book)/(100 - match_b_book)

Where ATW = amount to win in a back Dutching.

Would the condition "and selections trigger expression match_b_book is equal or less than 80" in the dutch trigger do the same thing mcbee /oxa?

A simple check proves that no, it wouldn't.

If match_b_book, say, is 75, then:

(100 - match_b_book)/match_b_book >= 0.2

is true, for 100-75/75 = 0.33.

Yet

match_b_book >= 80

is not true.

I did amend mine to "is equal or less than 80" as I realised my mistake after I posted, I'm sure this works?

If match_b_book, say, is 81, then:

(100 - match_b_book)/match_b_book >= 0.2

is true, for (100-81)/81 = 0.23.

Yet

match_b_book <= 80

is not true.

So no way trying to guess, use the formula I provided. :)
