I bought and sold this several times today. I did well buying as prices retreated from steps and selling when they got back to the previous level, but I am new at this and did not realize until after my last two buy trades that the chart had changed and started to slope downwards overall, not just the little stair steps down like before. This stock had multiple pauses through the day. Just saw a Tim Lesson saying not to trade these when they get halted. Good learning today.
