Struct BsmState 

Source 
pub struct BsmState { /* private fields */ }
Expand description

Mutable European option under BSM (spot / vol / time / strike updates).

Fallible constructor is BsmState::new → FinanceResult (Result-only naming).

Implementations§

Source§

impl BsmState

Source

pub fn new(params: BsmParams, option_type: OptionType) -> FinanceResult<Self>

Validate and store contract + market snapshot.

Source

pub fn params(&self) -> BsmParams

Source

pub fn option_type(&self) -> OptionType

Source

pub fn set_spot(&mut self, spot: f64) -> FinanceResult<()>

Underlier mark moved (most common live update).

Source

pub fn set_vol(&mut self, vol: f64) -> FinanceResult<()>

Set model / implied vol directly (absolute annualized).

Source

pub fn set_time_years(&mut self, time_years: f64) -> FinanceResult<()>

Clock / expiry decay — pass remaining time in years.

Source

pub fn set_strike(&mut self, strike: f64) -> FinanceResult<()>

Rarely changes live; included for completeness (e.g. corporate action resstrike).

Source

pub fn set_rate(&mut self, rate: f64) -> FinanceResult<()>

Source

pub fn set_dividend_yield(&mut self, dividend_yield: f64) -> FinanceResult<()>

Source

pub fn set_vol_from_price(&mut self, market_price: f64) -> FinanceResult<f64>

Invert market premium into IV and store it (trading: mark to mid).

Source

pub fn price(&self) -> FinanceResult<f64>

Model price at current params.

Source

pub fn greeks(&self) -> FinanceResult<BsmGreeks>

Model Greeks at current params.

Source

pub fn cross_greeks(&self) -> FinanceResult<BsmCrossGreeks>

Cross Greeks (vanna, volga, charm) at current params.
