Although dollar's brief rise to 87.78 in NZ today confirms recent corrective rise fm 2010 low at 86.27 has resumed and marginal gain can't be ruled out, above 88.00/02 (previous support) needed to bring stronger retracement of recent fall to 88.40/50 later.    Below 87.12/23 would signal intra-day top is made and yield stronger retreat to 86.73.
