Finally, I compare the four models through their statistics. The innovation of this article is to apply the method of Copula to calculate the ratio of margin and compare it with the other three models from the theory and empirical study. The theory is proofed feasible from the empirical study.In the margin system, the calculation of margin is the core issue, which directly affects the effectiveness of the other systems.
