Betfair Cash Out - how does it work.

[ken1921]

I'm curious how Betfair's cash out works

I have a Exchange back bet at 1.56. In the last 2 hours the lay odds have moved up and down by one tick but each time the cash out value has been different when I was expecting it to be the same when the lay odds value returns to it's previous value. So what is happening here?

Lay
Odds. Cash Out Value
1.58 -£0.38
1.57 -£0.20
1.58 -£0.28
1.57 -£0.17

Many thanks

it can be inaccurate, think there is a delay on the cash out amount shown too ( better using software!)

They use the full market to calculate their cash out values rather than simply the current odds of the selection you bet on. So it's a bit like cross matching rather than a simple trade of one runner and also they check the amounts on offer to fully cash out the bet so it may have been calculated across more than one odds increment depending on the bet size available

Betfair did have an article somewhere explaining cashout. It takes into account the amount of money available and I think only 80% gets placed at best price, the remaining 20% gets placed at second and third best price to increase the chances of matching. I'm sure you'd be better off greening up with BA or whatever trading software you use, which is usually more customisable.
