Machie,
I have not suggested sell at the open, merely be aware that the trading activity at the close last night suggests that a shortterm top is imminent. As a holder I hope that isn't the case.
The point I was trying to make is that you need to have a game plan before the event.
Sitting in front of the screen watching the trades move rapidly up or down and thinking "oh god, do i sell or not" usually doesn't produce the best outcome.
