Just say I bought the exchange traded fly +Jun13-2Sep13+Dec13 Is it possible to close out this position in the outrights? I.e. sell 1 Jun13, buy 2 sep13 and sell 1 dec13 I know that doing this will neutralize the position, but will the positions be aggregated at the end of the day? To put it another way, will my broker (or maybe the exchange?) combine the outright trades with the fly and consider the position closed?
