Really upset with this one. I sold it for no logical reason (I THOUGHT it would fail but it was showing all bullish signs - volume, holding trend line etc). It kept holding the trend line, then broke the HOD which was also the 52 week high. Left 10-15 percent on the table. Chased AVEO (exact same pattern as ZN) because it was closer to the high of the day and thought would break faster. Took a small loss on AVEO instead. Should of realized AVEO was over extended with its vertical moves.
