class Greeks.GreekFillers.DeltaGreekFiller.DeltaGreekFiller(delta_bump_size)

Class that retrieves the relevant market states for delta computation, computes the finite difference and fills the greeks dictionary.

Parameters:

delta_bump_size : float

The additive bump \(\epsilon\) applied on the underlying \(S\) for delta computation.

Methods

fill(...)

Retrieve the relevant market states for delta computation, computes the finite difference and fills the greeks dictionary .

fill(pvs: typing.Dict[Common.MarketStateKey.MarketStateKey, Common.PricingResult.PricingResult], results: typing.Dict[Common.ResultKey.ResultKey, float]) → None

Retrieve the relevant market states for delta computation, computes the finite difference and fills the greeks dictionary .

Parameters:

pvs : Dict[MarketStateKey, PricingResult]

Dictionary that maps each market state to the option price given that state.

results : Dict[ResultKey, float]

Dictionary that contains the results of greeks computation.

Returns:

None

>>> from Greeks.GreekFillers.DeltaGreekFiller import DeltaGreekFiller
>>> from Common.MarketStateKeys import MarketStateKeys
>>> from Common.ResultKeys import ResultKeys
>>> from Common.PricingResult import PricingResult
>>> pvs = dict()
>>> results = dict()

>>> pvs[MarketStateKeys.delta_down] = PricingResult(1.50,0.0,0.0,0.0)
>>> delta_filler = DeltaGreekFiller(delta_bump_size=1.0)
>>> delta_filler.fill(pvs, results)
>>> print(results[ResultKeys.delta])
