Dollar's strong rebound from yesterday's low at 88.02 suggests the pullback from Monday's 89.15 high has ended there and the erratic rise from July's 7-month low of 86.96 is expected to resume, above said resistance would yield subsequent gain to 89.46 but reckon 89.71 would hold.    On the downside, only below strong support 88.00/02 would risk stronger retracement toward 87.66 before up again.
