Abstract: The lattice Boltzmann model (LBM) is used to solve the pricing problem of the American lookback option.The domain truncation technique and the penalty method are used to transform the linear complementary model satisfied by the lookback option into a one-dimensional nonlinear parabolic problem on a bounded domain,and LBM is introduced for the transformed bounded domain problem.The macroscopic equation is recovered by selecting appropriate equilibrium distribution functions and amending functions.The numerical simulation results show that the option prices obtained by LBM agree well with the results derived from the binomial tree method and other methods,which verify the effectiveness of the model in solving the pricing problem of the American lookback option.

Key words: lattice Boltzmann model, American lookback option, linear complementarity problem, domain truncation technique, penalty method
