Although yesterday's breach of 87.23 resistance to 87.58 suggests further choppy trading above Friday's 2010 low of 86.27 would continue, outlook remains mildly bearish for recent downtrend to resume, below 86.64 would bring re-test of 86.27, then toward 85.86 later.    On the upside, only above the aforesaid resistance at 87.58 would bring stronger retracement towards 88.00/02.
