Complete back/lay bets

[eminbe]

Hi

I have an automation that places a lay bet of odds 3.0 on all selections for £10, as soon as one gets matched it cancels the rest. When the number of matched condition on the market is equal to 1.

In some occasions if a runner just hits 3.0 slightly and back high the lay bet gets a percentage on the £10 matched e.g. £2.50 out of £10.

I need some help here, is there a way to make the automation cancel all bets when £10 get matched in more than a runner if it don't get fully matched on the first runner.

For example:
Runner hits 3.0 and up high ---> giving £2.50 matched out of £10
The automation should reduce the lay bets from £10 to £7.50 and wait till the £7.50 gets matched on a different runner.
It should cancel all bets when £10 lay bet is match in different selections.

Thanks in advanve.
