From the view of BTA chart, it seems BTA is going to fail. It peaked at $3.47 on 16/10/09. Since then, it gradually declimed with a few lower high, $3.25 @17/10/09, 3.15@4/12/09, 2.59 @17/12/09, and lowered low, 2.63@21/10/09, 2.53 @ 27/11/09, 2.3@15/12/09 and 2.13@8/1/10(if it could hold for the moment). Short term, it could bounce up, but longer term it is bearish.
