Dan,
Trades over a certain size, a multiple of EMS(EMS 100k here) are delayed by one hour. Therefore, this site and others, are not sophisticated enough to work out what the price was an hour previous, so they get marked as unknown.
Even larger trades(over another multiple of EMS) are delayed 2 hours. Then even larger ones are reported the next day. Like the 6m buy at 0.98 reported after hours from yesterday.
