the key to successful trading is analytics not emotions. you should use this to identify your cover point. if you were trading short term yesterday may have been the day. if not then use the lower BB, which is rising with time. the key to failure is emotions, which are a contra- indicator. when you (as a short) are euphoric - cover. when you as a short are fearful - short. GL to you. You sound pretty euphoric right now.
I continue to be very bullish for the long term. The turnaround is working - first expenses (proven), then grow sales (not yet proven, although this was first Q with sequential growth and I think next quarter we see possibility of yoy growth). I think shorts who fail to take profits over time (short and hold forever) will lose six to sevenfold or more.
