Anomaly in horse race in running green up bot

[kenfrost]

Folks your input on this would be greatly appreciated.

I am currently testing a bot on in running horse races.

It has a back/lay liability of £4, and is designed to place a lay bet on a horse in running then (if the lay is matched) green up by 5 ticks with a back bet.

It has worked without glitches, until yesterday.

It placed a 29p lay bet at 13.50 which was fully matched.

It then greened up at 24p at 16.

The horse went on to win, and so I had a loss of 3p.

My question is this, why didn't it place a back bet of 25p? That would have given me a profit whatever the result.

To be absolutely clear, my log shows that the back bet was 24p and was fully matched (ie it didn't try to place 25p and only get 24p matched).

Thanks

Sounds like a rounding issue.

If you had it at 25p then thats an extra 16p so still wouldn't be exactly right


The larger the stakes, the less significant the rounding issue

Without doing the maths would have thought its some kind of rounding error

could be, thanks

thanks. Why would 16p extra be a problem? I seem to be not understanding something?

When you green up it tries to do it in the most balanced way possible.

So if you are -3p when it wins, that's more neutral than a +16p win

To put it in a more obvious context -

If your green up value is displaying as 50p. It would be better that a win gives you 48p, than 66p as the 48p is closer to the true profit value

Thanks, the mist of my misunderstanding has cleared
