Low risk entry against this breakout support (green box).
I like how it reacted to "old resistance" labeled with the red box.
For the fundamentalists: The story is that T-Mobile is paying to switch customers over to them, hence the new focus on the upside and you can see from the lack of free cash flow, that they need to do something to keep this $22 billion market cap afloat while revenues are only $7.88 billion.
If TMUS is up on the day I will consider a long position and risk a little less than 3 average daily ranges for a target of 3 average ranges. 50:50 payout, but better than 50:50 odds of a winner.
