Just happened to notice that one this morning. Not a good one to start a new position today, IMO, with pop at decision point of a negative descending triangle. Needs another few days to prove sentiment change, or 1st resistance actually broken, for new entry. Note; same thing happened end of June without follow through. It was added to my watch list. The one I got into this morning was CDXC which I just posted a chart on.
But if your down on TTOO and looking to get even. Things look a little better since the descending triangle has popped, not dove. Personally I'd sell half or more if $200 high is reached. And the second half at gap above fill, on continuation. But if continuation stalls above $2.00, I'd think about dumping the second half on 2nd red day.
