On the charts, LME tin and zinc look well positioned to push higher but technical indicators on nickel and aluminum are still pointing lower so expect further consolidation in these two metals, says Will Adams of BaseMetals.com. The pattern of strong market openings and a tail off in the afternoon seems to be developing while copper prices consolidate, but at some stage prices should push higher again, Adams says, adding the next upside objective is $8,000 a metric ton. LME copper trades at $7,711/ton, -0.3% from Monday.
