I know Sinofax reckons that big miners are in a new bull market but the charts do not look well today. In fact, as BHP tumbled -4% in London, RIO -2.9% and GLEN -3.6%, all three are sitting on very precarious supports with bearish patters to boot. BHP has a pretty good head and shoulders pattern and a descending triangle:

RIO has a near perfect head and shoulders pattern and is sitting right on the neckline:
