The Australian dollar retreats after a lacklustre retail sales reading in October. The pair is looking to hold onto its gains above 0.6700 following a rally earlier this month. A bounce off 0.6580 next to the 20-day moving average indicates interest in safeguarding the aussie’s recovery. 0.6720 is a fresh resistance and a close above 0.6800 would open the door for an extension to September’s peak of 0.6910. On the downside, a dip below said support would put the bulls on the defensive with 0.6400 as a second line of defence.
