make_finite_difference_accumulator_engine ​

cpp
Result<FiniteDifferenceAccumulatorEngine> kiyosi::make_finite_difference_accumulator_engine(FiniteDifferenceSettings settings)

Creates an engine after validating its configuration. 返回值: The engine, or an invalid_parameter error.

kiyosi::FiniteDifferenceAccumulatorEngine ​

cpp
class kiyosi::FiniteDifferenceAccumulatorEngine

Marches the accrual value back as an affine function of the accumulated quantity, so a single sweep prices every opening position. Accepts 3..2,000 asset steps and 1..2,000 time steps.

FiniteDifferenceAccumulatorEngine ​

cpp
kiyosi::FiniteDifferenceAccumulatorEngine::FiniteDifferenceAccumulatorEngine()=default

Creates an engine with valid default settings.

price ​

cpp
Result<double> kiyosi::FiniteDifferenceAccumulatorEngine::price(const Accumulator &option, const PricingContext &context) const

Prices an accumulator by finite differences. 返回值: Price, or a contract, context, or numerical error.

price_with_greeks ​

cpp
Result<PricingResult> kiyosi::FiniteDifferenceAccumulatorEngine::price_with_greeks(const Accumulator &option, const PricingContext &context, GreeksRequest greeks, NumericalShiftSettings settings={}) const

Prices with the explicitly requested Greeks; unavailable measures remain empty. Delta, gamma, and speed reuse the solved layers; vanna/zomma and charm/color difference native delta/gamma shifted in volatility and time. Other measures use numerical price differences.

settings ​

cpp
FiniteDifferenceSettings kiyosi::FiniteDifferenceAccumulatorEngine::settings() const noexcept

Returns the engine settings.
