【Abstract】 With the study on the per-duration stock market,the linear equation system was introduced so as to evaluate whether there exists the arbitrage opportunity.Besides,dealing with the solution of such system the trading strategies of the arbitrage were presented.Finally,based on the Farkas’ theory,a sufficient condition concerning the relationship between the arbitrage opportunity and risk neutral probability was offered.更多还原
