Despite this week's choppy trading after dollar's resumption of recent fall to 86.27 (Fri), as long as resistance at 87.58 holds, downside bias remains but firm break of 86.54 is needed to signal decline from 94.99 (May) has resumed, 86.27 and later toward 85.86.    On the upside, above the said resistance at 87.58 would confirm resumption of the rise and risk 87.95/00.
