This is a complex H&S forming on TWTR.
It's a bit complicated due to how pronounced the H&S is, so I've made the target a good bit short of what it actually would be if you used the general measure rule.
Tech, in the eye of the public is now carrying the generalization of being "overvalued".
Sentiment is also trashed due to all of the political risk out there.
Easy short, pyramiding position at break of the next trend-line.
