The contract broke above the upper trendline of the triangle that formed between $1,828 and $2,494, a bullish target at $3,403 has been established over a longer period of time.

But a realistic target within a four-week time frame will be at $2,800, as pointed to by an upper channel line, parallel to the lower trendline of the triangle.

Confirming the bullish outlook is the impulsive wave pattern on the rise from $1,279 to $2,494, as it indicates the current rally could be either a wave "C" or a wave (3), both are capable of pushing aluminium up to $3,043.

Support is at $2,480, a fall below which will extend to $2,400.
