Provided Methods

fn funding_fee_amount_per_size( &self, is_long: bool, is_long_collateral: bool, ) -> Result<Self::Num>

Get current funding fee amount per size.

fn claimable_funding_fee_amount_per_size( &self, is_long: bool, is_long_collateral: bool, ) -> Result<Self::Num>

Get current claimable funding fee amount per size.

fn validate_open_interest_reserve( &self, prices: &Prices<Self::Num>, is_long: bool, ) -> Result<()>

Validate open interest reserve.

fn min_collateral_factor_for_open_interest( &self, delta: &Self::Signed, is_long: bool, ) -> Result<Self::Num>

Get min collateral factor for open interest.

fn cap_positive_position_price_impact( &self, index_token_price: &Price<Self::Num>, size_delta_usd: &Self::Signed, impact: &mut Self::Signed, ) -> Result<()>

Caps positive position price impact in-place. If impact is not positive, the function does nothing.

fn cap_negative_position_price_impact( &self, size_delta_usd: &Self::Signed, for_liquidations: bool, impact: &mut Self::Signed, ) -> Result<Self::Num>

Caps negative position price impact in-place. If impact is not negative, the function does nothing.

Returns

• The capped amount of the negative impact.
