Downtrend, extending and oversold · RSI 24 · price 1.32414
Lower highs and lower lows since early Sep; post-Fed range broken lower.
Lower highs and lower lows have held since the 1.3568 early-September top. This week price broke out of the 1.3336–1.3400 post-Fed cap range and through 1.3300 former support, as a blowout US PMI beat and soft UK services data lifted USD. The move printed a 1.3223 swing low. RSI(14) near 24 is oversold, ATR(14) around 30 pips is expanding, and price sits below both EMA20 and EMA50, with EMA20 holding under EMA50.
Support: 1.3223, 1.3200
Resistance: 1.3300, 1.3336, 1.3400
What it said to watch
Failure to hold the 1.3223 swing low exposes the 1.3200 round number.
An H4 close back above 1.3300 former support would stall the breakdown. The 1.3336 prior low sits at the 61.8% fib of the latest leg.
The lower-highs trendline near 1.3355 and the 1.3400 post-Fed cap frame the upper edge of the downtrend.
Thursday's BoE speakers (Breeden, Dhingra, Lombardelli), US jobless claims and Fed's Williams could materially shift this read.
13:26 UTC
Downtrend, extending to new window lows · RSI 27 · price 1.32665
Lower highs since 1.3568; 1.3335–1.3400 range broken lower.
Lower-high structure has held since the 1.3568 early-September peak, with the Fed-driven drop through 1.3440 feeding a week-long 1.3335–1.3400 range where the 1.34 cap held four times. That range floor gave way this week, and today's soft UK services PMI against a hawkish-Fed dollar pushed price through the july low near 1.3274 to a new low at 1.3264. EMA20 remains below EMA50 with price under both, ATR(14) near 28 pips is expanding on the break, and RSI in the high 20s is oversold.
Support: 1.3264, 1.3200
Resistance: 1.3274, 1.3335, 1.3400
What it said to watch
H4 close back above the july low at 1.3274 would mark the break as a false break
Reclaim of 1.3300 and the range floor at 1.3335 would undercut the lower-low sequence
Round number 1.3200 is the next reference below the new low if the 1.3264 low gives way
US flash PMIs at 13:45 UTC and Fed's Barr at 14:05 UTC could materially shift this read
BoE's Breeden, Dhingra and Lombardelli on Thu could reprice November hike odds and move GBP
Lower-high trendline near 1.3360 caps any rebound; the 61.8% fib sits near the 1.34 cap
11:42 UTC
Downtrend, extending · RSI 31 · price 1.33022
Lower highs and lower lows, fresh 3-week low.
Unbroken sequence of lower highs and lower lows on H4 since the 1.3635 high three weeks ago, with each bounce capped progressively lower — 1.3400 (post-fed cap), then 1.3387 (prior high), and now the ema20 around 1.3348. The last two sessions broke the 1.3300 psych area that had held as the base of the mid-month consolidation, a move the digest ties to the August PSNB overshoot and softer UK services PMI against hawkish Fed repricing. ATR(14) near 26 pips is expanding versus the sub-20 pip compression seen mid-window, consistent with trend extension rather than range behaviour.
Support: 1.3300, 1.3274
Resistance: 1.3348, 1.3387, 1.3400
What it said to watch
Last close sits marginally above 1.3300 psych — a sustained H4 close below turns it into resistance and exposes the 1.3274 july low
Reclaiming the ema20 near 1.3348 would be the first break in the lower-high chain since the 1.3635 high
BoE speakers Thu 09:30 GMT (Breeden, Dhingra) and Lombardelli 14:00 GMT could materially shift this read
US flash PMIs and Thursday claims remain the USD-side catalysts for the channel to extend or stall
Unbroken lower highs / lower lows since 1.3635, new low at 1.3300.
Three weeks of clean downtrend structure: every bounce has failed lower, from the 1.3461 prior high through the 1.3398 swing high and now the 1.3349 lower high, with price closing at 1.3302 on a fresh cycle low. The descending channel has stayed intact throughout, driven by the Fed-BoE divergence story after the 16 September Fed hike and the BoE's 6-3 hold, which has capped every attempt at the 1.3400 area. ATR(14) near 26 pips is expanding rather than compressing, and price is trading below both EMA20 and EMA50, with RSI near 29 flagging an oversold but still trending market sitting directly on the 1.3300 psych level.
Support: 1.3300, 1.3274
Resistance: 1.3349, 1.3398, 1.3461
What it said to watch
Sustained H4 close below 1.3300 psych opens the july low at 1.3274 as the next reference
An H4 close back above the 1.3349 lower high would break the lower-high sequence and put 1.3398 swing high back in play
US flash services PMI at 13:45 UTC is the immediate lever on the dollar leg driving this move
BoE speakers Thu 24 Sep (Breeden, Dhingra 09:30 GMT; Lombardelli 14:00) could materially reprice the sterling side of this read
05:02 UTC
Downtrend, extending · RSI 31 · price 1.33159
Lower highs and lower lows within a descending channel; fresh low at 1.3315.
Sequential lower highs and lower lows since the 1.3640 area high three weeks ago, with price tracking the lower half of a descending channel and holding below both EMA20 and EMA50. The 1.3320-1.3330 shelf that held twice in the last two sessions gave way this bar to a new low at 1.3315, consistent with the hawkish Fed repricing and the UK fiscal overshoot flagged in the macro read. ATR(14) near 25 pips is mid-range for this window, so the move is grinding rather than impulsive, with the 1.3400 cap still unbroken since the Sep 16 Fed hike.
Support: 1.3315, 1.3300
Resistance: 1.3387, 1.3400, 1.3446
What it said to watch
Acceptance below the 1.3300 psych level would confirm channel continuation rather than a false break
A reclaim of the prior high at 1.3387 and a close above the 1.3400 cap would break the lower-high sequence
UK flash PMIs today plus US flash PMIs are the main near-term structural risk to this read
Failure to hold 1.3315 on a retest keeps the swing high at 1.3446 firmly out of reach
