DexCom appears to be in a Diamond Pattern while showing big MACD Hidden Bearish Divergence on the Weekly Timeframe that could later lead to a Confirmed ABCD/Gartley BAMM Harmonic breakdown upon the breaking the B point which from there likely could take it down to the Pattern Completion Zone of $30.64.
I will be playing this via the currently slightly OTM: FEB and MARCH $100 Striked Puts.
