It's a no-brainer to know what this dudes are up to. At $1.61 is our 200 day moving average line and as an avid follower of moving averages, these contact areas are so oftern used by would be shorts as an anticipated resistance level so they apply the pressure. We had a good run all the way up from about $1.10 and it seems logical for them to begin their attack.
Interesting though, is the weekly chart's MACD moving average lines. The shorter term one is ready to cross the slower one and it could result in an extra push higher on this move if it, does indeed, get penetrated to the upside. The days ahead should prove interesting. Will BMO and Anonymous succeed or will they be proven wrong?
