Implementations

impl PerpInfo

pub fn health_contribution(&self, health_type: HealthType) -> I80F48

Total health contribution from perp balances

For fully isolated perp markets, users may never borrow against unsettled positive perp pnl, there pnl_asset_weight == 0 and there can’t be positive health contributions from these perp market. We sometimes call these markets “untrusted markets”.

Users need to settle their perp pnl with other perp market participants in order to realize their gains if they want to use them as collateral.

This is because we don’t trust the perp’s base price to not suddenly jump to zero (if users could borrow against their perp balances they might now be bankrupt) or suddenly increase a lot (if users could borrow against perp balances they could now borrow other assets).

Other markets may be liquid enough that we have enough confidence to allow users to borrow against unsettled positive pnl to some extend. In these cases, the pnl asset weights would be >0.

pub fn weigh_health_contribution( &self, unweighted: I80F48, health_type: HealthType ) -> I80F48
