Yesterday's selloff below 106.71 (now resistance) indicates the erratic decline from 108.62 would extend towards previous support at 105.71 and a break there would confirm medium term downtrend has finally resumed and bring re-test of January's low at 104.95  
Above 107.15 (previous support) would signal a temporary low has been formed yesterday at 105.95 and yield correction to 107.40/50.
