ZINC - Seems it breaks monthly support

The lanted green support line has a crack.
It's a first indication of a turn in mid-term trend.

Long term Medianline view on ZINC shows that price is battling at the L-MHL. If we get a weekly close and new open below it, it's ripe for a short.
At least I will stalk it on the daily.

PTG1 is the Center-Line.
