COST support and resistance levels
Price was turned away at a ceiling near $1,124.42 about 5 weeks ago and has been sliding since. On the weekly chart, the next floor below sits near $844.06 — still about 12% 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.
Nothing here is a signal to act — the short would have set up at the $1,124.42 ceiling about 5 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 entry.
Nearest auto-detected support sits near $849.43, resistance near $1,085.36. These are chart/swing-derived levels, not formula pivots.
