Heating Oil .618 Retrace

Could be a complete series of abc's  up from the lows, hitting the .618 retrace point.
Back below 1.75 would confirm a reversal,  and nearer by under  a .618 retrace  of that leg @ 1.7930 would probably do it.

Longer term this would  imply a resumption of the downtrend.  See   Heating Oil Chills
