Uptrend, retesting yearly high · RSI 61 · price 0.82468
Higher highs and higher lows since late Aug; pullback held above 0.8183 swing low.
Higher-low structure has held since late August. The post-Fed pullback from the 0.8264 yearly high found demand at the 0.8183 swing low, near the 61.8–78.6% zone of the Sep impulse, and today's blowout US PMI beat lifted price back to 0.8260, where supply capped the move. ATR(14) has eased to about 20 pips from the Fed-week expansion, and price sits above both the ema20 and EMA50. The pair is compressing just under the yearly high ahead of the SNB.
Support: 0.8224, 0.8183, 0.8153
Resistance: 0.8264, 0.8300
What it said to watch
H4 close above the 0.8264 yearly high would extend the higher-high sequence and expose the 0.8300 round number
A second rejection at 0.8260–0.8264 followed by a break of the 0.8183 swing low would set up a double top and break the rising-lows line
Loss of the ema20 near 0.8224 would signal the PMI leg fading, with the 0.8153 prior low the next higher low below
SNB decision Thu 07:30 UTC (press conference 08:00): FX-language or inflation-forecast surprises could materially shift this read
US jobless claims and Fed's Williams on Thu could move the rate gap driving the pair
17:02 UTC
Uptrend, pressing the cycle high · RSI 59 · price 0.82508
Higher highs and higher lows since 0.8067; flag pullback resolved higher.
Higher-low structure has held since the 0.8067 low. The Fed-driven spike to the 0.8264 cycle high was followed by a shallow flag that bottomed at the 0.8183 swing low, close to the 38.2% retracement of the 0.8067–0.8264 leg. Blowout US PMIs and Fed-SNB divergence have lifted price back out of the flag and above both EMAs. ATR near 20 pips is steady rather than expanding, and the pair is now pressing the cycle high.
Support: 0.8200, 0.8183, 0.8153
Resistance: 0.8264, 0.8300
What it said to watch
SNB decision Thu 07:30 UTC: a hawkish hold or softer intervention wording could drag price back to the flag lows near 0.8200
H4 close above the 0.8264 cycle high extends the higher-high sequence and opens the 0.8300 round number
Failure to hold the 0.8183 swing low breaks the higher-low trendline and the 38.2% fib, exposing the 0.8153 higher low
US jobless claims and Williams/Hammack Fedspeak Thu could shift October hike pricing and the USD leg
13:27 UTC
Uptrend, pulling back into consolidation · RSI 55 · price 0.82344
Higher highs since 0.8052 low; post-breakout drift with lower highs below 0.8264.
The Fed hike drove a vertical break from the 0.8150-0.8199 shelf to a 16m high at 0.8264. Since then the pair has drifted in a shallow sequence of lower highs, and demand stepped in at the 0.8183 swing low, holding above the 78.6% fib of the 0.8153-0.8264 impulse. Price has reclaimed the 0.8200 round number and both EMAs, and is pressing the 0.8239 lower high, while ATR(14) has compressed to roughly 19-20 pips from the breakout expansion.
Support: 0.8200, 0.8183, 0.8155
Resistance: 0.8239, 0.8263, 0.8300
What it said to watch
H4 close above the 0.8239 lower high reopens the 0.8263 16m high; acceptance beyond it exposes the 0.8300 round number
Failure back below the 0.8200 round number and the 0.8183 swing low would confirm a lower-low and expose the 0.8155 range floor
US flash PMIs today 13:45 UTC and Fed's Barr at 14:05 UTC could shift the USD leg of this read
SNB decision Thu 07:30 UTC: the FX-intervention and inflation-forecast language is the swing factor for a break of either consolidation edge
Higher highs/higher lows since 0.8026, now consolidating under the 0.8239 range top.
The multi-week advance off 0.8026 has produced a clean sequence of higher lows, capped last week by the 0.8264 swing high printed on the hawkish Fed repricing that drove CHF to funding-currency lows. Since then price has gone sideways in a roughly 55-pip band between the 0.8183 swing low and the 0.8239 range top, holding above both EMA20 and the rising EMA50 near 0.8203, with RSI back to neutral around 50 and ATR(14) compressing to ~18 pips — a flag-type pause rather than a structural turn. Lower highs off 0.8264 mark the upper edge of that pause, while demand has stepped in twice near 0.8183.
Support: 0.8203, 0.8183, 0.8153
Resistance: 0.8239, 0.8264, 0.8300
What it said to watch
H4 close above the 0.8239 range top re-opens the 0.8264 swing high and the untested 0.8300 psych level
Loss of the 0.8183 swing low breaks the higher-lows trendline and exposes 0.8153 prior low
SNB decision Thu 07:30 GMT plus press conference 08:00 GMT is the main event risk for this consolidation
US flash PMIs today 13:45 GMT could resolve the compression in either direction
Sustained trade back below the ema50 at 0.8203 would weaken the higher-low structure
Higher lows intact, lower highs since 0.82638 peak.
The advance from the 0.80258 low into the 0.82638 range high was driven by hawkish Fed repricing after the September 16 hike; the last two weeks have been a grinding pullback with successive lower highs from 0.82638 through 0.82389 to 0.82230, while the 0.8200 round number and the 0.81833 swing low have absorbed repeated probes. Price is now pinned just above both EMA20 and EMA50, which are flattening, and ATR(14) has compressed to roughly 18 pips from the 30-pip regime of the impulse leg — a coiled flag inside the larger higher-low sequence. RSI near 47 is neutral, consistent with corrective rather than impulsive price action.
Support: 0.8200, 0.81833, 0.81752
Resistance: 0.8223, 0.82389, 0.82638
What it said to watch
H4 close above the 0.82230 lower high would end the sequence of lower highs and re-open 0.82389
Loss of 0.81833 on a closing basis breaks the higher-low structure that has held since the 0.80258 low
SNB decision Thu 07:30 UTC and press conference 08:00 UTC is the dominant event risk for this range
US flash PMIs later today can resolve the ATR compression in either direction
Higher lows intact, lower highs since 0.8264 — converging into a flag.
The three-week advance off 0.8016 remains a higher-low sequence, but price has spent the last ten sessions drifting lower inside a descending flag after the post-Fed impulse topped at the 0.8264 month high; the 0.8225 range cap has now capped four attempts. Price is sitting on the 50% retracement of the 0.8153–0.8264 impulse at roughly 0.8209, below EMA20 but still above EMA50 near 0.8186, with CHF firmer for a fourth day as USD longs get trimmed. ATR(14) near 18 pips is mid-range for the window, with the descending highs and the rising higher-low line converging toward the 0.8183 week low.
Support: 0.8183, 0.8175, 0.8153
Resistance: 0.8225, 0.8254, 0.8264
What it said to watch
H4 close below the 0.8183 week low breaks the higher-low sequence and exposes the 0.8175 impulse base, then the 0.8153 swing low
Reclaim of the 0.8225 range cap on a closing basis re-opens the 0.8254 prior high and the 0.8264 month high
US flash PMIs today 13:45 UTC and the SNB assessment Thu 07:30 UTC are the events most likely to resolve this compression
