Although yesterday's selloff from 86.25 to 85.17 signals dollar's minor correction from Friday's 8-month low at 85.02 has ended and intra-day downside bias remains, below said support needed to re-test 84.82 (Nov 09), break there would extend downtrend toward 84.00/10.  
On the upside, only above the said resistance at 86.25 would bring stronger retracement to 86.46 before another retreat.
