RE:RE:RE:RE:RE:Decison Time Its been my experience that Bollinger Bands work best when the underlying security exhibits an accretive style return profile , when a security is more episodic (return happens suddenly sharp upside or downside price action). They are useful , when a stock is episodice to ot trnd potential not mean reversion. IMHO we see $7 to $8 before we visit a sub 4 handle again. Trade smart and safe the commodity curve underpinning value is notouriously dangerous.
above is just my opinion does not make it so ...do your own technical work , if inclined study up on fat tail distributions , which is heurestically biased to the right
