I am looking at versio 5.8, com-ex41-oil-asian-barrier-option-strip.xml. I am new to this so please forgive my lack of understanding but I thought, a European option was exercised at expiry time, an American option could be exercised at any time up to and including expiry time and an Asian could be exercised at expiry time but was an average of the underlying over the period of the option. The example mentioned has a series of Exercise dates as well as a termination date which does not seem to stack up, any help would be appreciated
