Lower highs since 0.8395; flat range 0.8222-0.8270 above swing low.
The PPI-driven spike to the 0.8395 swing high failed quickly. USD/CHF shed about 175 pips as US yields and oil eased on US-Iran deal hopes, leaving a double top with the 0.8382 high from earlier in the window. Price has since held a tight range between the 0.8222 range low and the 0.8270 range cap, just above the 0.8218 swing low. It trades below both EMAs with EMA20 under EMA50, and ATR(14) has compressed to about 22 pips from the expansion seen during the selloff.
Support: 0.8222, 0.8218, 0.8200
Resistance: 0.8270, 0.8300, 0.8395
What it said to watch
H4 close below the 0.8218 swing low confirms the double top and exposes the 0.8200 round number
Close above the 0.8270 range cap and the lower-highs trendline puts the 0.8300 psych level back in play
Range compression near 0.8222-0.8270 suggests a directional break is pending
US jobless claims Thu and S&P Global PMIs Fri could shift yields and break the range
FOMC next week; a flagged December hike would challenge the downtrend read toward the 0.8395 swing high
US 10y yield back above 5.12% would signal the dollar pullback is ending

Downtrend from 0.8395, basing at neckline · RSI 52 · price 0.82578
USD/CHF has a double top in place at 0.8382/0.8395. The dollar has been on the defensive as near-term Fed hike pricing faded and US housing data missed, driving a roughly 175-pip slide to the 0.8222 neckline. Since then the pair has held a tight 0.8222–0.8270 range below a descending sequence of lower highs, with price back over EMA20 but still beneath EMA50. ATR(14) has compressed from about 40 pips during the selloff to the low-20s, so the neckline is now the pivot for the next swing.
Support: 0.8222, 0.8200, 0.8196
Resistance: 0.8270, 0.8300, 0.8395
What it said to watch
H4 close below the 0.8222 neckline confirms the double top and exposes the 0.8200 round number and the 0.8196 window low
H4 close above the 0.8270 lower high breaks the descending trendline and opens the 0.8300 round number, near the 38.2% fib
Fri Oct 23 US S&P Global PMIs (high impact) could materially shift this read
FOMC next week; a hawkish December-hike signal would challenge the double top read
Lower highs from 0.8395; tight band above neckline.
USD/CHF has rolled over from a double top at 0.8382/0.8395. Fed-pause repricing and softer UST yields after the hot CPI/PPI spike drove a 177-pip slide to the 0.8218 swing low, which wicked through the 0.8220 neckline without a close below it. Since then price has compressed in a 0.8220–0.8270 band under a falling EMA20, which has crossed below EMA50. ATR(14) has eased to ~21 pips, the bounce high stalled short of the 38.2% fib at 0.8286, and the old 0.8300 range floor now sits overhead.
Support: 0.8220, 0.8200
Resistance: 0.8270, 0.8300, 0.8395
What it said to watch
H4 close below the 0.8220 neckline confirms the double top and exposes the 0.8200 round number
Close above the 0.8270 bounce high and the 0.8286 38.2% fib breaks the lower-highs sequence
Reclaim of the 0.8300 range floor would negate the double top read toward 0.8395
US jobless claims Thu and S&P Global PMIs / UoM inflation expectations Fri could shift this read
FOMC next week: a hawkish hold flagging December would challenge the neckline test
Double top at 0.8382/0.8395; lower highs, tight base above 0.8218.
Twin highs at 0.8382 and 0.8395 formed a double top. The roughly 1.4% reversal from the second peak came as dovish Fed commentary, falling Treasury yields and AI-led equity jitters outweighed hot US data, and it carried price to a 0.8218 swing low just through the 0.8227 neckline. Since then USDCHF has held a narrow 0.8233–0.8270 base below a bearish EMA20/EMA50 cross, with the EMA50 converging on the 0.8300 psych level, while ATR(14) has contracted to about 21 pips from the selloff's expansion.
Support: 0.8227, 0.8218, 0.8200
Resistance: 0.8270, 0.8300, 0.8395
What it said to watch
H4 close below the 0.8218 swing low confirms the neckline break and exposes the 0.8200 round number
Close above the 0.8270 range top and the lower-highs line shifts focus to the 38.2% selloff fib near 0.8286 and the 0.8300 ema50/psych zone
Recovery through 0.8300 would undercut the double top read; 0.8395 remains the cycle high
Fri Oct 23 S&P Global PMIs and the US 10y yield around 5.13% could materially shift this read
Lower highs since 0.8395 peak; double top neckline 0.8227 tested, not closed below.
The spike to 0.8395 on hot US CPI reversed fully as US yields slid on AI-equity stress. That left a double top against the late-September 0.8382 high, with the neckline at 0.8227. Price wicked to a 0.8218 swing low without a close below the neckline, and the rebound stalled at the 0.8270 bounce high. That high sits near the 23.6% retracement and under a lower-high trendline drawn from the 0.8316 lower high. Price is below both EMA20 and EMA50, and ATR(14) has eased to ~21 pips from ~40 during the sell-off, a sign the pair is compressing above the neckline.
Support: 0.8227, 0.8218, 0.8200
Resistance: 0.8270, 0.8300, 0.8316
What it said to watch
H4 close below the 0.8227 neckline confirms the double top and exposes the 0.8200 round number
Close above the 0.8270 bounce high and the lower-high trendline opens the 0.8286 38.2% retracement and psych 0.8300
Reclaiming the 0.8316 lower high negates the lower-highs sequence
US S&P Global PMIs Fri Oct 23 13:45 UTC could materially shift this read via US yields
FOMC next week and shifts in Fed hike pricing are the main swing factor
Double top 0.8382/0.8395, neckline 0.8227 held on closes.
USD/CHF has a double top in place at 0.8382/0.8395. The 1.4% slide from the second peak tagged a swing low at 0.8218, a false break of the 0.8227 neckline with no H4 close beneath it, as a sharp drop in US yields and AI-tech risk aversion hit the dollar. The rebound to 0.8267 coincides with the 10y back near 5.13% and is now pressing the ema20 near 0.8271, with the ema50 near 0.8290 above. ATR(14) has compressed to about 22 pips from the post-peak expansion, and price sits below the 38.2% fib of the decline.
Support: 0.8227, 0.8218, 0.8200
Resistance: 0.8271, 0.8300, 0.8395
What it said to watch
H4 close below the 0.8227 neckline confirms the double top and exposes the 0.8200 round number
Acceptance above the ema20 and psych 0.8300 negates the double top read and reopens the 38.2% fib near 0.8286
A run back toward the 0.8395 double top high would need US 10y yields holding above ~5.13%
