Dollar's selloff below 107.42 support on Friday in line with the greenback's weakness across the board suggests the erratic decline from last week's top at 108.59 to retrace recent upmove would extend to 106.90/00, however, anticipated oversold condition should prevent steep fall below support at 106.56.  
On the upside, above resistance at 108.08 (Friday's high) would indicate aforesaid fall has ended and risk gain towards 108.40/44.
