Yesterday's cross-inspired rebound from 107.21 suggests the correction from last week's top at 108.62 has possibly ended and consolidation with upside bias is seen, however, a break above 108.33 is needed to confirm recent upmove has resumed and bring subsequent re-test of said resistance.  
On the downside, below support at 107.21 would risk another corrective fall to 106.99 and then towards 106.50/60 before prospect of a recovery.
