$PACB inlast one hour went dn from $13.73 to $13.18 and then spiked again to $13.73. I couldn't judge if it was goin to spike from $13.18 and thought it might keep going down since it was the last hour. How to tell if the spike from $13.18 was not going to be a fake out. Or is it just about taking a chance. Are there other factor to consider to be a little more confident about the move the stock is going to make?
