Hedge variant's

Hi all
I’m thinking about variant’s of covering some yiled strategies that i’m doing somewere else but on token’s that frikiton has.
*For example *
that’s a good yeild on AVA i
buy it or land USD and borrow AVA,
then i put it in LP with some stable
and to cover AVA movements open on option

But here i got a questions:
what amount i need to put into call/put to cover possible AVA movements in this case?
How to count it?
Is t there is a fix rate in Vaults, what’s is going in option and what % go to cover it?

thanks
