Pullback from 0.8395 high, stabilising below EMAs · RSI 44 · price 0.8267
Double top at 0.8382/0.8395, neckline 0.8227 holding on closes.
The September advance from 0.8183 left twin highs at 0.8382 and 0.8395. That forms a double top whose neckline at 0.8227 was pierced intrabar to the 0.8218 swing low, though no H4 bar closed below it. Since then a rebound line of higher lows from 0.8218 has lifted price back to the ema20 near 0.8270 as US yields recover. EMA20 sits below EMA50, and ATR(14) near 24 pips has compressed from last week's expansion.
Support: 0.8227, 0.8218, 0.8183
Resistance: 0.8270, 0.8300, 0.8327
What it said to watch
H4 close below the 0.8227 neckline and 0.8218 swing low confirms the double top and exposes the sept low at 0.8183
Acceptance above the ema20 and the 38.2% fib at 0.8286 puts the 0.8300 round number back in play; reclaiming it weakens the double-top read
Break of the rebound line under 0.8245 returns focus to the neckline
Fib 61.8 at 0.8327 is the deeper retracement ceiling of the 0.8395-0.8218 drop
Friday US PMIs and the US 10y yield near 5.13% could materially shift this read
Double top 0.8382/0.8395, neckline 0.8227 tested, tight base below ema20.
USDCHF carved a double top at 0.8382/0.8395 and dropped 177 pips from the swing high as US yields slid after dovish Fed comments and AI-linked risk aversion lifted CHF. The selloff stalled at the 0.8218 swing low, just under the 0.8227 neckline, and price has since built a 0.8233–0.8270 consolidation with ATR(14) easing to roughly 24 pips. The latest bar is pressing the base top into the ema20 near 0.8272 as US yields rebound, while EMA20 holds below EMA50 after last week's ema cross.
Support: 0.8227, 0.8218, 0.8200
Resistance: 0.8272, 0.8300, 0.8395
What it said to watch
H4 close above the 0.8300 psych level and the 38.2% fib (~0.8286) undermines the double top read and refocuses on the 0.8395 swing high
Close below the 0.8227 neckline and the 0.8218 swing low confirms the double top, exposing the 0.8200 round number
Rejection at the ema20 (~0.8272) keeps the post-top consolidation intact beneath resistance
US 10y yield around 5.13% and Friday's S&P Global PMIs could materially shift this read; a renewed AI-tech equity selloff is the main downside tail

Downtrend from 0.8395, stalling at neckline · RSI 36 · price 0.82412
Double top at 0.8382/0.8395 with lower highs since; price pinned to the 0.8227 neckline.
The spike to 0.8395 on hot US inflation data failed below the early-October 0.8382 high. Dovish Fed remarks and softer Treasury yields then drove a 175-pip unwind into the 0.8227 neckline, completing a double-top shape. Price wicked to the 0.8218 swing low but H4 closes keep holding above the neckline, and EMA(20) has crossed below EMA(50). ATR(14) has eased to around 27 pips from the spike-driven expansion, leaving price compressing on the neckline with the ema20 near 0.8275 overhead.
Support: 0.8227, 0.8218, 0.8183
Resistance: 0.8275, 0.8300, 0.8395
What it said to watch
H4 close below the 0.8227 neckline confirms the double top and exposes the 0.8183 sept low
Holding the 0.8218 swing low keeps the neckline retest unresolved; a reclaim of the ema20 at 0.8275 would ease downside pressure
Recovery above the 0.8300 range floor (also near the 50% fib) negates the double-top read and reopens the 0.8395 double top
Thu US Initial Claims and Fri S&P PMIs and UoM 5y inflation expectations could materially shift the neckline test

Downtrend, testing the neckline · RSI 34 · price 0.82346
Double top 0.8382/0.8395, lower highs, price at the 0.8227 neckline.
Hot US CPI lifted the pair to a double top at 0.8395 (prior peak 0.8382). Dovish Fed remarks and falling yields then drove a ~180-pip unwind back to the 0.8227 neckline. The 0.8218 swing low wicked through it, but H4 closes have so far held above, and the bounce high near 0.8260 is capping. Price sits below both EMAs after a bearish EMA20/50 cross, RSI is low-30s and ATR(14) near 28 pips is still elevated from the breakdown.
Support: 0.8227, 0.8218, 0.8183
Resistance: 0.8260, 0.8300, 0.8395
What it said to watch
H4 close below the 0.8218 swing low confirms the double top, with the 0.8183 sep low next
A recovery through the 0.8260 bounce high and then the 0.8300 round number (50% fib zone) would neutralise the breakdown read
