Dollar's intra-day rally from 98.80 in part due to cross selling in yen suggests the choppy trading inside 98.56-101.04 would continue and mild upside bias is seen for gain to 100.40 (Friday's high) but a firm break there is needed for re-test of 101.40 later.  
On the downside, below 98.80 yields another fall to 98.56 and breach of latter level would extend the erratic decline from 101.04 towards 98.00.
