Another words like Bollinger Bands? dey dont do anything but tell u where its been, no imagination nor in da formula that puts the bands on da graph. when i see anything similar, its just semantics, technical stuff that one puts on a graph, its the interpretation that means everything in investing. and technical charts without fundamentals means nothing, cause u have to know why the technicals are doing what they do and where they may go, its all in the interpretation.
