First, the minor at 82.02 was broken, followed by the next minor support at 81.84.
A move below the major support at 81.37 will break the going back to the September 2013 low, effectively breaking the recent uptrend.
Unfortunately, that's precisely what I'm expecting given the corrective pattern unfolding off the January highs. In terms, the pattern appears to be a double (2 consecutive 3-wave patterns), labeled WXY. Utilizing the theory that corrective patterns tend to channel around 90% of the time, an area price target of 80.80 to 81.16 seems reasonable for the intermediate term.
What comes next is far less clear in the long term, but a bounce that lasts for a period of at least several weeks is reasonable. A longer term view will require that a new is established up or down, or an 8-wave EW setup ( 5-wave impulse followed by an correction). I wouldn't be surprised at all if prices were confined in this narrow 2015 range for the remainder of the year.
