Variants

Sizing(SizingError)

Existing policy, price, or floating-point sizing validation failed.

UnsupportedInstrumentSizing

The instrument quantity and P&L model combination is not supported by this sizing path.

Fields

quantity_unit: QuantityUnit

Instrument quantity unit.

pnl_model: EconomicsModelId

Instrument P&L model.

MissingNativeToAccountRate

Catalog-backed monetary sizing did not receive a native-to-account conversion rate.

InvalidNativeToAccountRate

The supplied native-to-account conversion rate is not usable.

Fields

value: f64

Invalid conversion rate.

ExactDecimalOutOfRange

The exact instrument decimal cannot be represented as a finite f64.

Fields

field: &'static str

Instrument field being converted.

value: Decimal

Exact value that could not be converted.

UnsupportedQuantityGridOrigin

The quantity grid origin is incompatible with the retained zero-based lot-step result.

Fields

value: Decimal

Unsupported grid origin.

QuantityBoundOffGrid

An exact quantity bound is not on the declared quantity grid.

Fields

field: &'static str

Quantity bound field.

value: Decimal

Off-grid exact quantity.

InvalidQuantityBounds

The exact quantity bounds are inconsistent.

Fields

minimum: Decimal

An exact quantity bound cannot be represented as a supported lot-step count.

Fields

field: &'static str

Quantity bound field.

value: Decimal

Exact quantity that overflowed.

InvalidQuantityGrid(GridError)

Exact quantity-grid arithmetic failed.

PriceOffGrid

A replay price is outside the declared price grid.

Fields

field: &'static str
