Following discord thread and Bugfix explanations (thanks you!), I now think that -4 is the more fair for everyone, as it is based on position size and not on collateral. I’m against differentiating users based on their positions size or leverage. Every trader using the protocol as intended should be considered the same.
I also think that Perp should try to compensate for the remaining losses (with a debt token , vested Perp, etc)
Good luck to the team and to every perpv1 traders impacted, I hope we will find a solution!
