Uptrend, pressing 16-month high · RSI 64 · price 0.83576
Higher highs and higher lows since the 0.8183 low.
Higher-low structure has held since the 0.8183 low. The leg through the 0.8300 pivot came after the dovish SNB shift on 24 Sep, and resilient US growth data (GDP, Chicago PMI beats) has so far offset the soft PCE. Price is retesting the 0.8358–0.8362 16m high, with the 0.8321 swing low beneath. EMA20 sits above EMA50 and price trades above both. ATR(14) is steady near 20 pips, so the trend is extending without expanding and RSI is not yet overbought.
Support: 0.8321, 0.8300, 0.8272
Resistance: 0.8362, 0.8400
What it said to watch
H4 close above the 0.8362 16m high extends the trend and opens the 0.8400 round number
Failure to hold the 0.8321 swing low and a break of the rising trendline would mark the first lower low of the leg
Loss of the 0.8300 pivot exposes the 50% fib near 0.8272
Swiss CPI (Thu 06:30 UTC) and US ISM Manufacturing with Waller (Thu 14:00 UTC) could materially shift this read
Higher highs and higher lows since 0.8183, tight 0.8321-0.8358 hold.
USDCHF has built a clean higher-high, higher-low sequence from last week's 0.8183 swing low. The leg accelerated after the dovish SNB hold and has been carried by a firm USD, with dip-buyers absorbing today's soft core PCE on the back of GDP and Chicago PMI beats. Price is now consolidating in a narrow band between the 0.8321 swing low and the 0.8358 16-month high, well above the rising support line. EMA20 remains stacked above EMA50 and ATR(14) near 20 pips shows no expansion yet.
Support: 0.8321, 0.8300, 0.8271
Resistance: 0.8358, 0.8400
What it said to watch
H4 close above the 0.8358 16m high extends the higher-high sequence and brings the 0.8400 round number into view
Failure to hold the 0.8321 swing low exposes the 0.8300 pivot, with the fib 50% retracement at 0.8271 below
A break of the rising support line from 0.8183 would mark the first structural crack in the swing sequence
Swiss CPI Thu 06:30 UTC (f/c 1.0% y/y) could materially shift this read
US ISM Manufacturing and Fed's Waller Thu 14:00 UTC are the larger event risk for the 0.8358 16m high
13:03 UTC
Uptrend, pausing below the high · RSI 65 · price 0.83463
Higher highs and higher lows, tight band under 0.8358.
Higher highs and higher lows have held since the 0.8067 base early in the window. The SNB's dovish shift on 24 Sep added the latest leg to a swing high at 0.8358, and price has since held above the rising EMA20 in a 0.8324–0.8358 band. Today's mixed US data (soft core PCE, firm GDP and ADP) left the pair closing near the top of that band, and ATR(14) near 20 pips shows compression under the swing high.
Support: 0.83242, 0.8300, 0.8271
Resistance: 0.83585, 0.8400
What it said to watch
H4 close above the 0.8358 swing high extends the higher-high sequence and brings the 0.8400 psych level into view
H4 close below the 0.8324 swing low opens a deeper pullback toward the 0.8300 pivot
Loss of 0.8300 exposes the fib 50% retracement at 0.8271, where it lines up with the prior swing low
Rising trendline from the 0.8067 and 0.8183 lows sits near 0.8256; a break there would end the multi-week higher-low read
Swiss CPI Thu 06:30 UTC and US ISM Thu 14:00 UTC, with NFP later in the week, could materially shift this read
Higher highs / higher lows since 0.8052, tight consolidation under 0.8358.
Higher-high / higher-low structure has held since the early-month 0.8052 low. The leg from the 0.8183 swing low ran to the 0.8358 swing high as the dovish SNB hold and firm Fed-hike pricing widened the rate gap, clearing the prior high at 0.8264 along the way. Price is now chopping just under 0.8358 and pressing the rising trendline from 0.8183. ATR(14) has eased to about 19 pips, which reads as a pause rather than trend expansion.
Support: 0.8304, 0.8271, 0.8264
Resistance: 0.8358, 0.8400
What it said to watch
US ADP (12:15 UTC) and core PCE (12:30 UTC) today could materially shift this read; a soft core PCE print has more room to trigger a pullback given rich hike pricing
Swiss CPI Thu 06:30 UTC (f/c 1%); a hot print would challenge the franc-weakness leg
H4 close below the 0.8304 swing low breaks the higher-low sequence and exposes the fib 50% at 0.8271 and the prior high at 0.8264
Sustained trade beneath the rising trendline from 0.8183 would mark the leg as losing momentum
H4 close above the 0.8358 swing high extends the uptrend toward the 0.8400 round number
Higher highs and higher lows since the 0.8052 early-month low.
Higher-high, higher-low structure has held since the 0.8052 early-month low. The latest leg ran from the 0.8183 swing low to a 0.8359 swing high, clearing the 0.8339 16-month high as the dovish SNB hold and hawkish Fed repricing weighed on the franc. Price is now holding a tight shelf above the 0.8332 swing low, with EMA20 above EMA50 and ATR(14) steady near 19 pips, so the trend is extending rather than compressing.
Support: 0.8332, 0.8300, 0.8271
Resistance: 0.83585, 0.8400
What it said to watch
US ADP (12:15 UTC) and core PCE (12:30 UTC) today could materially shift this read
Swiss CPI Thu 06:30 UTC; a hot print could trigger a pullback toward 0.8300 psych
H4 close below the 0.8332 swing low exposes 0.8300 psych and the 50% fib at 0.8271
Close above the 0.8359 swing high opens the path to the 0.8400 round number
A break of the rising trendline from the 0.8067 low (near 0.8250) invalidates the higher-low structure
01:02 UTC
Uptrend, extended near highs · RSI 68 · price 0.83425
Higher highs and higher lows since early-September low.
Higher-low structure has held since the 0.8052 early-September low, with the higher-low trendline well below price after last week's dovish SNB hold and hawkish Fed pricing lifted the pair through the 0.8298 range top. Price set a swing high at 0.8359 and the latest bars are holding just above the 0.8332 swing low. EMA20 sits above EMA50, RSI is elevated near 68 and ATR(14) around 19 pips shows steady rather than explosive expansion.
Support: 0.8332, 0.8298, 0.8264
Resistance: 0.8359, 0.8400
What it said to watch
Core PCE and ADP today (Sep 30) could materially shift this read
Swiss CPI Thu 06:30 UTC is the CHF-specific risk to the move
H4 close below the 0.8332 swing low exposes the 0.8298 range top as a retest zone
Failure to hold the range top brings the 0.8264 range low and the 50% fib near 0.8271 into view
H4 close above the 0.8359 swing high opens the path toward the 0.8400 round number
