Greening on Profit or loss % of stake

[Ianhski]

Hi again

This is for Horses in-play and I am exploring Servants and their uses.

If I have an automation or manual bet running where for example I have placed a lay with offset & Green

But I think that I may have been over optimistic so I want to trigger a servant that would either

1) Get out at an acceptable green, determined as a % of stake
or
2) Exit at a degree of loss, also a % of stake.

I may even add this to the automation itself but in general I want that to do its stuff but if I am monitoring the race, a servant would allow me to jump in.

Can a single rule do this or do I set 2 rules?

And when we say % of stake, I would probably be laying by liability so will it calc on actual stake or the liability value? I would imagine the rule would apply to back or lay of course.
