Falling Wedge · playing out now

COST Support and Resistance Levels

Price was turned away at a ceiling near $1,130.12 about 2 months ago and has been sliding since. On the weekly chart, the next floor below sits near $844.06 — still about 9% away.

Traders commonly watch $844.06 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 $1,130.12 ceiling about 2 months 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.
