Not much history to go by chart wise or fundamentally. If you were in the right place at the right time you would have gotten in on a huge run but it's now very over bought and needs to prove that it's worth that price. I'd say the emotion is running out fast and it time to fill gaps.
If in I would take profits and buy on the break do 1.60. I don't agree that it's over-bought, but it is trading sideways in a channel that could break up or down at any given time. Plan the trade and trade the plan, right and to me it needs to prove it can exit the channel with volume.
