18th July, 2013 AUDUSD - up or down? How to trade this pair? Short at all highs?

Following up on the current direction of the AUD, it was unusual that the AUD strengthened although the RBA stated a possibility of further easing activity, but was satisfied with the current stance on monetary policy. However, nibbling on the long side on the way up netted me some small profits and I also managed to take a sell towards the peak, as I sold near to the point of the upper trendline as I believed that that was the extent of the upwards retracement on a bigger timeframe (H4 chart)

Currently, the AUDUSD has moved back into within the trend channel created from the high of 11th April, 2013 to the high of 11th July, 2013, therefore I am of the assumption it will continue the downtrend, as the RBA has not ruled out further easing of the currency if required.
