We propose and analyse a new Milstein type scheme for simulating stochastic\ndifferential equations (SDEs) with highly nonlinear coefficients. Our work is\nmotivated by the need to justify multi-level Monte Carlo simulations for\nmean-reverting financial models with polynomial growth in the diffusion term.\nWe introduce a double implicit Milstein scheme and show that it possesses\ndesirable properties. It converges strongly and preserves non-negativity for a\nrich family of financial models and can reproduce linear and nonlinear\nstability behaviour of the underlying SDE without severe restriction on the\ntime step. Although the scheme is implicit, we point out examples of financial\nmodels where an explicit formula for the solution to the scheme can be found.\n
