WST Support and Resistance Levels

Price was turned away at a ceiling near $367.25 about 3 weeks ago and has been sliding since. On the weekly chart, the next floor below sits near $221.11 — still about 37% away.

  • Traders commonly watch $221.11 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 $367.25 ceiling about 3 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 $314.29, resistance near $356.89. These are chart/swing-derived levels, not formula pivots.
