Thank you four wonderful lectures. Just question about closing option. In lecture regarding interest it was mentioned that we don’t gave to execute option. But if understood well at lesson regarding currency exchange optons we have to always execute them and close them (even if there is loss?).
No. Options do not have to be exercised (and they will not be exercised if there is a loss. Maybe you are confusing with futures because the futures deal has to be closed off whether there is a gain or a loss.
