You did the right thing staccani.
Delays and lack of clarity ARE scary. I would suggest, however, that if you were once a believer in this stock, you keep close track on German revenue announcements, or lack of same. If they actually realize some $ by end of year, that would be a tip off that maybe, just maybe, this thing has a chance. BUT, at that point there would be plenty of time for you to jump back in to capture the upside. I have no positions currently, sold out my trading longs yesterday, so I will refrain from posting again until I take another side of fight, financially. If this gets under 5.70 I may look to take another long trade. With possible catalysts, real or hyped, on the horizon, I would suggest that people not short this thing right now.
