IMHO it is just normal resistance. If you look at the 3 year chart you will see that back in October 2007 the 1.70 area seemed to be a big resistance point. Once we break the 1.70's it should be an easy ride up to the $2.15 - $2.25 range which is where there was good resistance back in January of 2007
i am not an expert of charting... just in my own opinion. i would seek confirmation from someone that knows what they are talking about :)
