I'm not sure re:connection between FTSE and AUS/USD but FTSE has always been a strange beast with Banks, Chemicals and Oil skewing its movement compared to rest of market - and I've been caught out on a number of occasions... I think AUS/USD more to do with gold and probably movement in Chinese markets at present.
May well go down but my point is when markets making new highs with some significant news also due next couple of days - take a brave man to call tops... imo further extensions highly probable in next two days.
