As dollar has risen again after Friday's strong retreat from 104.82 to 103.90, suggesting the 'erratic' upmove fom 08' low at 95.77 to correct medium-term downtrend has once again resumed, however, a breach of strong res at 105.00 is needed to retain bullish bias for further subsequent gain to 105.20/30, weakening of upward momentum should cap price at 105.50/55 today.  
On the downside, below 104.30/40 would defer present bullish scenario and may risk a re-test of aforesaid Friday's low at 103.90.
