Most likely zinc is just starting to show initial signs, yet it's a fairly strong indication of higher side move.
As long as it continues to stay above the breakout level, & closes above 238, the probability of higher levels seems fairly strong.
At this point of time, targets of 260 to 280 seem be doable.
The upside view gets invalidated, if the breakout fails and zinc starts to close and sustain below 232 levels.
Unlike stock charts that I typically study, the volumes here are not very helpful in understanding the breakout better.
Due diligence advised. This view is purely for study purposes.
