<t>Thank you daveangel.I think that this can be cured by pricing with carrying cost theoretically. However, it seems that there is still an accounting issue. Say, we have sold a call option expiring on Sep and hedging it with June future. Suppose we hedged the option perfectly until May. On someday ...

Thank you daveangel.Most people are directly using that formula on Hull's book for a long time. It is difficult to make a correction now.

I thank your results are correct and I have no problem in calcuating h.However, after obtaining h, how to calculate the number of foward contract N one needs to hold?My result is N = h*QA*S/(QF*F)but John Hull's book suggestsN = h*QA/(QF)Where QA is Size of position being hed...
