Dollar's selloff from 85.91 (Mon) to yesterday's low 83.83 strongly suggests recent downtrend has resumed and expect minor consolidation before extending weakness to 83.70/80, however, below last week's 15-year low at 83.58 needed to yield further decline to 83.00/10.  
On the upside, above 85.15 would prolong choppy trading n yield gain to 85.46.
