Implementations

impl CurrencyPair

pub fn new_checked( id: InstrumentId, raw_symbol: Symbol, base_currency: Currency, quote_currency: Currency, price_precision: u8, size_precision: u8, price_increment: Price, size_increment: Quantity, lot_size: Option<Quantity>, max_quantity: Option<Quantity>, min_quantity: Option<Quantity>, max_notional: Option<Money>, min_notional: Option<Money>, max_price: Option<Price>, min_price: Option<Price>, margin_init: Option<Decimal>, margin_maint: Option<Decimal>, maker_fee: Option<Decimal>, taker_fee: Option<Decimal>, ts_event: UnixNanos, ts_init: UnixNanos, ) -> Result<Self>

Creates a new CurrencyPair instance with correctness checking.

Notes

PyO3 requires a Result type for proper error handling and stacktrace printing in Python.

pub fn new( id: InstrumentId, raw_symbol: Symbol, base_currency: Currency, quote_currency: Currency, price_precision: u8, size_precision: u8, price_increment: Price, size_increment: Quantity, lot_size: Option<Quantity>, max_quantity: Option<Quantity>, min_quantity: Option<Quantity>, max_notional: Option<Money>, min_notional: Option<Money>, max_price: Option<Price>, min_price: Option<Price>, margin_init: Option<Decimal>, margin_maint: Option<Decimal>, maker_fee: Option<Decimal>, taker_fee: Option<Decimal>, ts_event: UnixNanos, ts_init: UnixNanos, ) -> Self
