Possible Dow Chemical multi-decade breakout

DOW broke out 17-month triangle last week and today confirmed break with test of the trendline.
Decisive weekly close above 2005&2015 all time highs would clear way to strong multidecade breakout.
First support at 55.00. Anticipatory long in today at 55.35. Will add if all time high cleared. SL weekly close below triangle.
