$COST pulled back to $516 and then took off again so I believe this Subwave 1 is not complete yet and we have not experienced Subwave 2 yet.
I mentioned before that any pull back is a buy here as the upside potential is a lot.
If you have not added, maybe waiting for Subwave 2 to complete is the smart strategy now.
When I see Subwave 1 completing, I will add the Subwave count.
Either way, I see no issues with this going back up to the First Target at $585.
