I hate to admit it but you are right. It broke 6.36 easily last week. I think it will go past 6.55 this week. It looks to me it's next level of resistance is around 6.78.
As a side note its well known on this board that I have shorted this on pops but I will admit at least for the time being the longs finally have the momentum and would not be surprised to see it hit 7 next week.
This thing is heavily shorted. Last week I tried to short at 6.36 and Scottrade had no shares to short.
Look for a squeeze this week.
