Dollar's breach of resistance at 90.99 last Friday confirms the rise from last month's low at 87.13 has resumed and correction of medium-term decline to 92.70 and 93.00/10 would follow, however, overbought condition should cap upside below 93.50 and risk has increased for a retreat to take place later this week.  
On the downside, below 91.20/30 would signal temporary top has possibly been formed and bring a pullback towards support at 90.79.
