The upbar on 15 JAN 2010 is confusing, the volume under it being the factor. If you zoom out of your chart sufficiently, then you will find a trading range at the same price level during JUN 2010. Hence, its is not clear whether the professional money has sold into the high volume or absorbed from locked in traders. In hind-sights, few warning signals could be found(but I am not sure if they really "exist" or it is my subconscious bias as I have seen the chart), but doing it on immediate basis is difficult. Anyways, let learn and move on.
