Chart is BHP Billiton...a diversified ore producer.
I have highlighted prior crossover areas for bearish moves but ADX strongly up and any crossover would provide the strongest signal of a DMI+ above the ADX and DMI- being below to confirm a directional move. Using weeklies we got a buy signal at 856p and trade is profitable but the real longer term signal is currently building. Weeklies suggest the old cup and saucer pattern fwiw.
For long term positional trades you need a spread of 10+ on dmi+/dmi- also if both of these are above the ADX do not trade the signal as it implies market chop only and not direction.
