Although dollar has continued to trade sideways after last week's strong rebound from 89.75 to 90.81, this move signals the pullback from 91.09 high has ended there, upside bias remains and above 90.81 would yield resumption of erratic upmove from 88.14 to re-test said top and then further headway to 91.55/60.   
On the downside, only below 89.75/83 support area would yield stronger retracement of aforesaid rise to 89.10/20 before rebound occurs.
