AMT Support and Resistance Levels

Price was turned away at a ceiling near $189.86 about 8 weeks ago and has been sliding since. On the weekly chart, the next floor below sits near $170.46 — still about 2.7% away.

  • Traders commonly watch $170.46 as a target (its 100% retracement) — think of it as a sensible next stop, not a guarantee.
  • That floor is the first place the slide might steady — worth watching how price behaves as it gets there.
  • There's nothing to act on here — the spot to watch was the $189.86 ceiling about 8 weeks ago, when price was turned away there, but price has already pulled lower. What's left is the slide playing out, not a fresh starting point.

Nearest auto-detected support sits near $168.59, resistance near $191.50. These are chart/swing-derived levels, not formula pivots.
