21:02 UTC

Downtrend, steady grind lower · RSI 42 · price 1.33436

Sequence of lower highs and lower lows; fresh low at 1.3321.

Unbroken lower-high / lower-low structure over the three-week window, price sliding from 1.3650 to a fresh swing low at 1.3321 within a clean descending channel, with EMA20 near 1.3372 and EMA50 above it both overhead. The 1.3335 shelf that held repeatedly last week gave way on the Fed-BoE divergence theme and the UK borrowing overshoot, leaving 1.3300 as the next psych reference while 1.3400 has capped every rally attempt for four sessions. ATR(14) around 28 pips is mid-range — the move is extending steadily rather than impulsively.

Support: 1.3321, 1.3300

Resistance: 1.3372, 1.3400, 1.3435

What it said to watch

  • UK flash PMIs Wed 08:30 UTC and US flash PMIs 13:45 UTC are the window's main structural risk on both legs
  • An H4 close back above the 1.3400 capped-4x area, and then 1.3435 first barrier, would break the lower-high sequence
  • Acceptance below the 1.3321 swing low puts the 1.3300 psych level in play; failure to break it would leave a double-bottom attempt
  • Reclaiming the ema20 near 1.3372 on a closing basis would be the first sign the channel is flattening

17:02 UTC

Downtrend, extending lower · RSI 38 · price 1.33241

Lower highs and lower lows; range floor broken.

Unbroken sequence of lower highs and lower lows since the 1.3655 print three weeks ago, with price now 330 pips below that swing high and trading under both EMA20 (~1.3370) and EMA50 (~1.3395). The 1.3355–1.3400 band that contained the last four sessions has given way: the latest bar closed at 1.33241, beneath last week's 1.3335 floor, with the Fed–BoE rate differential and the £18.27bn August borrowing overshoot cited as the drivers. ATR(14) near 28 pips is stable rather than expanding, so this is a grind lower rather than an impulsive leg, and RSI at 38 is soft without being washed out.

Support: 1.3323, 1.3300

Resistance: 1.3355, 1.3400, 1.3435

What it said to watch

  • A close back above 1.3355 would frame the move as a false break of the range floor
  • Failure to hold 1.3300 psych level confirms continuation of the lower-low sequence
  • UK flash PMIs Wed 08:30 GMT and US flash PMIs 13:45 UTC are the nearest catalysts that could reset this read
  • Four failed sessions at the 1.3400 cap remain the ceiling reference on any recovery toward 1.3435 prior high

13:02 UTC

Downtrend, momentum stalling · RSI 45 · price 1.33619

Lower highs and lower lows since 1.3655; last 10 bars coiling inside a 1.3326-1.3398 range.

Price has stair-stepped lower for three weeks from 1.3655, carving an unbroken sequence of lower highs and lower lows, and now sits below both EMA20 (~1.3373) and the declining EMA50 near 1.3425. The last ten bars have compressed into a 1.3326-1.3398 range, with the 1.3400 range cap capping every attempt higher while the range low at 1.3326 has absorbed two probes — the softer UK PSNB print (£18.3bn vs £15.7bn) and the Fed's upgraded hike path are the macro backdrop. ATR(14) at ~25 pips is well off the 40-60 pip bars seen during the mid-window breakdown, so the trend impulse has drained even though the structure has not turned.

Support: 1.3326, 1.3300, 1.3272

Resistance: 1.3400, 1.3435, 1.3425

What it said to watch

  • H4 close above the 1.3400 range cap would break the three-week lower-high sequence and open the 1.3435 prior high and EMA50 at 1.3425
  • Failure to hold the 1.3326 range low confirms continuation toward 1.3300 psych and the 1.3272 measured ext
  • UK flash PMIs Wed 08:30 UTC (Services f/c 52.0) then US flash PMIs 13:45 UTC are the events most likely to resolve the current compression
  • Sustained ATR expansion back above ~40 pips would signal the range has broken rather than merely widened

09:02 UTC

Downtrend, momentum flattening · RSI 44 · price 1.33534

Lower highs and lower lows; last 8 bars ranging above the 1.3335 base.

Unbroken sequence of lower highs from 1.3655 has carried price roughly 320 pips lower, with the hawkish Fed hike against a 6-3 BoE hold widening the rate gap and the £18.3bn borrowing overshoot adding a domestic drag. The last eight bars have stalled in a tight 1.3335-1.3400 range, capped below EMA20 near 1.3375 with EMA20 under EMA50, and ATR(14) has compressed to about 24 pips from 50-70 pips during the impulse legs. The 1.3335 base has been tapped twice without follow-through, so the multi-day read is a pause inside a downtrend rather than a completed low.

Support: 1.3335, 1.3300

Resistance: 1.3375, 1.3400, 1.3445

What it said to watch

  • H4 close above the 1.3400 range cap, and then 1.3445 swing high, would break the lower-high sequence
  • Failure to hold 1.3335 last wk low confirms a lower low and exposes the 1.3300 psych level
  • Reclaiming EMA20 near 1.3375 on a closing basis would be the first sign the compression is resolving higher
  • UK flash PMIs Wed 08:30 GMT and US flash PMIs Wed 13:45 UTC are the nearest catalysts capable of resolving the range

05:02 UTC

Downtrend, momentum flattening · RSI 47 · price 1.33819

Lower highs intact, price basing above 1.3336 shelf.

Three weeks of sequential lower highs from 1.3654 have carried cable into a tight 1.3336-1.3398 shelf, with the 1.3400 round number capping the last several attempts and EMA50 at 1.3432 sloping down above price. The hawkish Fed dot plot against a 6-3 BoE hold set the drift, and Friday's retail sales beat was surrendered inside the same range rather than breaking it. ATR(14) near 25 pips marks clear compression versus the 45-65 pip bars seen during the mid-window leg lower, and price is now pressed against a flattening EMA20 — a coil rather than a trend extension.

Support: 1.3336, 1.3300

Resistance: 1.3400, 1.3432, 1.3445

What it said to watch

  • UK flash PMIs Wed 08:30 GMT are the window's main catalyst for this range
  • H4 close above the 1.3400 round number would be the first in several sessions and neutralises the lower-highs read
  • Loss of the 1.3336 swing low confirms continuation and exposes the 1.3300 psych level
  • Reclaim of EMA50 at 1.3432 and the 1.3445 swing high would break the descending resistance line

01:02 UTC

Downtrend, momentum stalling · RSI 46 · price 1.3369

Lower highs and lower lows, now compressing above the 1.3336 swing low.

The H4 series has printed an unbroken sequence of lower highs and lower lows since the 1.3655 area at the start of the window, accelerating after the Fed's hawkish 25bp hike and the BoE's 6-3 hold left rate divergence working against sterling. Price has spent the last six bars in a 40-pip band between the 1.3348 pivot lows and the 1.3400 cap, with ATR(14) near 23 pips — a clear compression against the prior impulse legs. Both EMA20 and EMA50 sit above spot and the descending lower-highs line has capped every bounce attempt.

Support: 1.3348, 1.3336, 1.3300

Resistance: 1.3400, 1.3445

What it said to watch

  • Failure to hold 1.3336 confirms continuation of the lower-low sequence toward the 1.3300 round number
  • A sustained H4 close above the 1.3400 cap would break the compression and put the 1.3445 broken low back in play
  • UK flash PMIs Wed 08:30 GMT and US PMIs 13:45 UTC are the only high-impact prints inside the next bar sequence and can reset this range read
  • Repeated rejection at the lower-highs line keeps the downtrend structure intact
