and Vorst A.C.P. This paper presents a simple binomial algorithm as one way to implement the Hull and White approach to valuing lookback European options Journal of Differential Equations , 251 (11), 3063-3089. Especially, valuing them requires a solution for the free boundary problems, an approach which is similar to the valuation of other American options.

Fixed strike lookback options, as the name suggests, have a fixed strike price like most other options contracts. American options and other path-dependent options, not just for discrete barrier and lookback options.

I get a call option price as minus 4.24$ i.e a negative number , any explanations please. In this paper, we will introduce a numerical method to price the European lookback floating strike put options where the underlying asset price is modeled by a generalized regime-switching jump diffusion process. A lookback option is settled on the basis of either minimum or maximum underlier value achieved till the option expires. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative American lookback option with fixed strike priceâ2-D parabolic variational inequality, Chen, X., Yi, F., & Wang, L. (2011). By using Itô formula and Wick-Itô-Skorohod integral a new market pricing model is built. for Pricing Barrier Option 1998 2. An American lookback option involves the combination of two exotic features: early exercise fea-ture and lookback feature. lookbacksensbyls calculates values of fixed- and floating-strike lookback options. Broadly speaking, general methods will be less efﬁcient than the methods which take advantage of the special struc-tures of discrete barrier and lookback options… As an approximation, we will apply a time-discretization and a truncation of the innite space.
