Required methods

fn on_serp_initialize(
    now: BlockNumber,
    sett_price: Self::Balance,
    sett_currency_id: Self::CurrencyId,
    jusd_price: Self::Balance,
    jusd_currency_id: Self::CurrencyId
) -> DispatchResult[src]

fn adjustment_frequency(adjustment_frequency: BlockNumber) -> DispatchResult[src]

The time used to denote the frequency of price elasticity adjustment; just a BlockNumber.

fn on_block_with_price(
    currency_id: Self::CurrencyId,
    block: BlockNumber,
    price: Self::Balance
) -> DispatchResult[src]

Contracts or expands the currency supply based on conditions.

fn serp_elast(
    currency_id: Self::CurrencyId,
    price: Self::Balance
) -> DispatchResult[src]

Expands (if the price is high) or contracts (if the price is low) the currency supply.

fn supply_change(
    currency_id: Self::CurrencyId,
    price: Self::Balance
) -> Self::Balance[src]

Calculate the amount of supply change from a fraction given as numerator and denominator.
