21:03 UTC
Uptrend, extended after impulse · RSI 71 · price 0.82453
Higher highs and higher lows; post-breakout consolidation under the 16-mth high.
Sequence of higher highs and higher lows has run uninterrupted from the 0.7983 low, and the FOMC hike bar cleared the 0.8191 prior high in one 88-pip candle to the 0.8264 16-mth high — the widest single H4 range in the window. Price has since gone sideways in a tight 0.8225–0.8264 band with ATR(14) around 20 pips, well above the 12-pip readings that preceded the break, so the expansion regime is still active rather than resolved. Both EMA20 and EMA50 sit below price and are rising, while RSI in the low 70s shows the move is stretched without any lower high yet forming.
Support: 0.8225, 0.8191, 0.8153
Resistance: 0.8264, 0.8275, 0.8300
What it said to watch
H4 close above 0.8275 band top would extend the breakout toward the 0.8300 psych level
Loss of the 0.8225 range low on a closing basis would put the 0.8191 prior high back in play as the first test of the breakout
A close back under 0.8153 swing low would break the higher-low sequence
SNB decision and press conference on 24 Sep is the main scheduled event risk for this structure
17:03 UTC
Uptrend, extended after breakout · RSI 69 · price 0.82482
Higher highs and higher lows since 0.7983; consolidating under 16-month high.
Three weeks of unbroken higher highs and higher lows off the 0.7983 base, with the hawkish Fed hike and dot plot triggering a near-70 pip impulse bar that cleared the 0.81911 pre-breakout ledge and printed a 16-month high at the 0.82638 range top. Price has since gone sideways between that range top and the 0.82225 range floor while EMA20 and EMA50 stay stacked beneath spot, so the trend structure is intact but the last four bars are net flat. ATR(14) near 21 pips is inflated by the single breakout bar; the follow-up range is narrower, which is typical post-impulse digestion rather than expansion.
Support: 0.82225, 0.81911, 0.81532
Resistance: 0.82638, 0.8300
What it said to watch
H4 close above the 0.82638 range top opens the path to the 0.8300 psych level
Loss of the 0.82225 range floor would put the pre-breakout shelf at 0.81911 back in play
A close back below the 0.81532 swing low would break the higher-low sequence
SNB decision on 24 Sep and the tone of the press conference are the main scheduled risk to this read
15:21 UTC
Uptrend, extended after impulse · RSI 75 · price 0.8254
Higher highs / higher lows; consolidating just under the range top.
Unbroken higher-low sequence since the 0.8052 swing low in late August, with the hawkish Fed against an SNB pinned at 0% driving a single 70-pip H4 impulse bar through 0.8196 to a 16-mo high at 0.8264. The last four bars have gone flat in a tight 0.8237–0.8262 band, so price is digesting directly beneath the range top at 0.8275 with 0.8300 the next round-number barrier above. ATR(14) near 19 pips is inflated by that one expansion bar; RSI in the mid-70s shows the up-leg is stretched rather than reversing.
Support: 0.8225, 0.8191, 0.8160
Resistance: 0.8264, 0.8275, 0.8300
What it said to watch
H4 close back below the 0.8225 range base would break the post-breakout consolidation and open the 0.8191 brkout base
Loss of 0.8191 would put the rising ema50 near 0.8160 back in play and end the higher-low sequence
A sustained H4 close above 0.8275 extends the up-leg toward the 0.8300 psych barrier
Fed's Bowman and US Industrial Production on Fri 18 Sep, then the SNB decision on 24 Sep, are the events most able to reshape this structure
13:03 UTC
Uptrend, extended after breakout · RSI 72 · price 0.8254
Higher highs and higher lows, fresh 16-month high, now consolidating under it.
Sequence of higher highs and higher lows has been intact for three weeks, and the hawkish Fed hike triggered an 88-pip expansion bar that broke the 0.8199 shelf and printed a 16-month week high at 0.8264. Price has since gone flat in a 0.8250-0.8264 coil with EMA20 above EMA50 and both beneath spot, so the breakout has not yet been given back. ATR(14) near 20 pips is inflated by that single impulse bar; the four bars since show renewed compression directly under the highs.
Support: 0.8225, 0.8185, 0.8155
Resistance: 0.8264, 0.8300, 0.8350
What it said to watch
H4 close above the 0.8300 round number would confirm the breakout is extending rather than stalling
Failure to hold the 0.8225 range low would put the 0.8185 swing low back in play and break the higher-low sequence
RSI above 70 with price stalling under the week high sets up the conditions for bearish rsi divergence if a new high is made on weaker momentum
US jobless claims / Philly Fed today and the SNB assessment on 24 Sep are the events most able to reshape this structure
13:03 UTC
Uptrend, extending after breakout · RSI 72 · price 0.8254
Higher highs / higher lows since 0.8052; new consolidation above the broken 0.8199 prior high.
Three weeks of stair-step higher lows off 0.8052 culminated in an impulsive H4 candle that cleared the 0.8199 prior high and printed a 16-mo high at 0.8264, driven by the policy-divergence trade — a hawkish Fed hike against an SNB expected to sit at 0%. The four bars since have gone sideways in a tight 0.8237–0.8264 band with ATR(14) around 21 pips, so the expansion candle has been digested rather than reversed. Price holds well above both EMA20 and EMA50, with the EMAs stacked bullish since early in the window, while RSI in the low 70s shows momentum stretched at the highs.
Support: 0.8237, 0.8199, 0.8185
Resistance: 0.8264, 0.8300
What it said to watch
Sustained H4 acceptance above 0.8264 would open the path to the 0.8300 round number, the next real gate
Loss of the 0.8237 consol low, then a close back under the 0.8199 prior high, would mark the breakout as a false break
0.8185 key support is the level whose failure would break the higher-low sequence
US claims and Philly Fed today, plus the SNB assessment on 24 Sep, are the events most able to reprice this structure
11:49 UTC
Uptrend, extended after impulse · RSI 78 · price 0.82584
Higher highs and higher lows, pausing above broken prior high.
USDCHF has built higher highs and higher lows across the three-week window, lifting from the 0.7972 area to a 0.82638 range high, and the 0.81990 prior high was cleared by the widest bar in the window before price flattened into a tight consolidation between 0.82366 and 0.82638. The advance fits the digest's framing of CHF as G10's weakest link and funding currency of choice, with the USD leg — post-NFP dovish repricing versus safe-haven demand — dictating pace. ATR(14) near 19 pips is up sharply from the sub-13-pip compression that preceded the breakout, so volatility is expanding rather than fading, with price stretched above both EMA20 and EMA50.
Support: 0.82366, 0.8199, 0.81532
Resistance: 0.82638, 0.8300
What it said to watch
Acceptance above the 0.82638 range high opens the path to the 0.83000 round number
An H4 close back below the 0.81990 prior high would negate the breakout read
Loss of the 0.82366 consol low would put the breakout bar's body back in play, with 0.81532 swing low the base of the current leg
US CPI is the dominant catalyst for the USD leg and can reshape this structure within the next few bars
