Friday's cross-inspired rally previous resistance at 84.89 (now support) confirms recent downtrend has formed a temporary low at 83.58 last Tuesday and outlook is supportive for further gain towards 85.80/90 after consolidation, however, near term over-bought condition should cap dollar's below 86.39 and bring retreat later.  
On the downside, below 84.60/70 would signal aforesaid correction is over instead and shift risk for weakness towards 84.27.
