Below is a 10 day chart of PRB from bigcharts.com. In reference to the red converging Bollinger Bands, the proabilities are high that a noticable move is near. It is also noticed that anonymous is feeding shares into the market at the top band. If this top band gives way to increased buying the result could be another nice move and in the process hook anonymous.
