Copper steady atm after 4 up days and China PMI was good news for a return to modest growth which should support Cu and in turn is good for AVB as it heads towards production.
For the TA savy out there (which I'm not) I have noticed recently that when the bots play the buy side it seems to be followed by a good up day and when for the first time on Wed I think we saw bots on the sell side it was followed by a small retrace. Anything in it? Just thought it was interesting.
