Despite yesterday's rebound after falling to a new 3-year low at 102.60, as the price action from there looks corrective, reckon 104.00 would limit upside and yield another fall, below 102.90/95 would signal downtrend has resumed and bring re-test of said support first.  
Only a break above resistance at 104.36 would risk stronger correction of recent decline towards 104.95 (previous support).
