I like this one outside the downward diagonal trendline .
Earnings are coming pretty fast so don't forget that fact.
I was hoping for a bigger drop but support seems pretty decent in that area with the red POC 5.71% and two Tim West Key Option Levels ( KOL -1.44% ) in the support area .
Note that one of the KOL -1.44% is actually hidden by the POC 5.71% as they share the same level.
The stock will do what it needs to do but I would not be surprised to see the stock ramp up along the edge of the lower Linear Regression channel.
The yellow area will be my stop-loss area.
Since ALGN -0.70% are selling items like the Invisalign braces, they might be a lot more "Tweet-Resistant" than many of the other healthcare suppliers Trumps likes to torment slowly one Tweet at a time.
