AddOption vs AddOptionContract and Price models

Back

When backtesting with options I have seen that it is much more efficient to select the contract you are interested in and use AddOptionContract than to use AddOption for the security at the beginning.

The problem is that I have been unable to get an Option Price Model to work using the AddOptionContract approach? Is is possible to use price models with AddOptionContract? Is there any example available?

Thanks,
Felipe

Hi xxxxxx xxxxxx,

Yes. You can use SetSecurityInitializer:

def Initialize(self)
self.SetSecurityInitializer(self.OptionInitializer)

def OptionInitializer(self, security):
if security.Type == SecurityType.Option
security.PriceModel = OptionPriceModels.CrankNicolsonFD()

or you can set it right after the contract is added:

option = AddOptionContract(symbol)
option.PriceModel = OptionPriceModels.CrankNicolsonFD()
