Thank you for the good advice.
As I can't afford to sit on dead money, I took the risk of selling with an order registered right before open @$.4098. Then I had an appointment but when coming back to the action, I was pleased to see that I spotted the right price action as my sell order got filled almost optimally before price retraced back. So, as for now I'm out.
But I believe in this stock, hence, if I see no better transitory use of the money made available, I will reenter FCEL around $.33 e.g. possibly tomorrow before close, if there are no other news.
Btw, I'm so addicted to FCEL that I already resisted to reenter around $.35 today, LOL
