21:03 UTC

Recovery uptrend stalled, momentum neutral · RSI 46 · price 157.344

Lower highs off 159.03 swing high; compressing range above 156.50.

The rebound from the 152.89 early-month low ran into a rejection at the 159.03 swing high, as Trump's yen concern and the joint US-Japan intervention message knocked USD/JPY lower. The pullback found a floor at the 156.50 weekly low, near the 38.2% retracement of the 152.89-159.03 leg. Price has since compressed between 156.50 and the 157.85 lower high, with ATR(14) near 49 pips versus 100+ early in the month and price sitting just under a flattening EMA20/EMA50 pair.

Support: 156.50, 155.96, 155.23

Resistance: 157.85, 158.40, 159.03

What it said to watch

  • H4 close below the 156.50 weekly low exposes the fib 50% at 155.96 and the fib 61.8% at 155.23
  • H4 close above the 157.85 lower high breaks the descending trendline and reopens the 158.40 prior high
  • 159.03 swing high is the upper marker; a return there is likely to draw fresh MoF/US Treasury pushback
  • MoF intervention data and US core PCE/ADP on Wed Sep 30 could materially shift this read
  • Tankan (Wed 23:50 UTC) and Tokyo CPI (Thu) feed October BoJ hike odds

17:03 UTC

Recovery uptrend stalled, pulling back · RSI 45 · price 157.511

Pullback from 159.03 held 156.50 swing low; range 156.50-157.85.

The higher-high, higher-low recovery from the 152.89 low topped at the 159.03 swing high. Price then dropped after Trump's yen comments and the live intervention threat, and the retest of the 156.50 swing low held just under the 38.2% fib. Since then the pair has compressed into a 156.50-157.85 range, with the range high a lower high versus 159.03. Price sits below EMA20 but above EMA50 as ATR(14) contracts to roughly half its early-window level, while Fed October hike pricing cushions the downside.

Support: 156.94, 156.50, 155.96

Resistance: 157.85, 158.40, 159.03

What it said to watch

  • H4 close above the 157.85 range high reopens the 158.40 prior high and the 159.03 swing high
  • Failure at the 156.94 range low and a break of the 156.50 swing low would confirm a lower low and expose the 50% fib at 155.96
  • Wed MoF intervention data and the Tankan could decide which range edge gives way
  • Wed ADP and Core PCE could materially shift this read via US yields

13:02 UTC

Uptrend stalling, rolling into consolidation · RSI 45 · price 157.146

Lower high at 157.85 after 159.03 peak; higher-low line intact.

The recovery from the 152.89 early-month low built higher lows into the 159.03 swing high. Friday's yen-concern selloff rejected that peak, and price is now compressing between a 157.85 lower high and the 156.50 swing low, below both EMA20 and EMA50. ATR(14) has contracted to about 50 pips from more than 100 early in the window, and price is holding the 23.6–38.2% retracement of the rally with the rising support line from 155.33 still intact.

Support: 156.50, 155.96

Resistance: 157.85, 159.03

What it said to watch

  • H4 close above the 157.85 lower high reopens the 159.03 swing high
  • Failure to hold the 156.50 swing low and rising support exposes the 50% fib at 155.96
  • JOLTS today 14:00 GMT, then ADP and GDP Wed 12:15–12:30 GMT, could break the compression
  • Wed MoF intervention data and Tankan at 23:50 UTC could materially shift this read

09:03 UTC

Uptrend from early-month low, momentum stalling · RSI 43 · price 157.413

Higher lows intact since 152.89; lower high at 157.85 after the 159.03 peak.

USD/JPY still holds the higher-low sequence from the 152.89 early-month low. It rolled over from the 159.03 swing high as Trump's yen remarks and intervention threats capped the Fed-hike bid, and Monday's low at 156.51 tested the 38.2% fib zone of that advance. Price is compressing between the ema20 (~157.60) and ema50 (~157.10) and is probing the rising trendline, with ATR(14) near 48 pips, roughly half the early-September regime.

Support: 157.10, 156.505, 155.96

Resistance: 157.854, 159.032, 160.391

What it said to watch

  • H4 close below the 156.51 monday low breaks the higher-low sequence and exposes the 50% fib at 155.96
  • Close above the 157.85 lower high reopens the 159.03 swing high; the sept high at 160.39 sits in the intervention-sensitive zone
  • Sustained trade below the rising trendline and ema50, with ema20 crossing under ema50, would mark the swing turning
  • JOLTS and Consumer Confidence at 14:00 UTC and heavy Fedspeak through 19:00 UTC today could materially shift this read
  • MoF intervention data and Tankan (Wed 23:50 UTC) are JPY-side event risk for the compression

05:02 UTC

Recovery stalled, sideways below 159 · RSI 43 · price 157.431

Higher lows from 152.89 broken by 156.50 undercut; range 156.50–157.85.

The recovery from the 152.89 low built higher lows into a 159.03 swing high, where intervention warnings and Friday's Trump-driven yen move produced a rejection. The pullback dipped to a 156.50 swing low, just under the prior higher low and near the 38.2% fib of that recovery. Price is now boxed between 156.50 and the 157.85 range top, with EMA20 flat at price and still above EMA50 near 157.15. ATR(14) at about 48 pips is roughly half the early-month selloff pace, so the range is compressing.

Support: 156.50, 155.30

Resistance: 157.85, 158.40, 159.03

What it said to watch

  • H4 close below the 156.50 swing low confirms a lower-low and exposes the 155.30 prior lows, which sit near the 61.8% fib
  • H4 close above the 157.85 range top and the lower-highs line reopens the 158.40 prior high and the 159.03 swing high
  • EMA20 crossing below EMA50 would mark the recovery sequence as rolled over
  • JOLTS today, Wednesday's ADP and MoF intervention data, and the Tankan at 23:50 UTC Wednesday could each break the 156.50–157.85 range

01:02 UTC

Recovery uptrend stalling, lower high in place · RSI 43 · price 157.361

Contracting range between rising higher-low line and falling lower-high line.

The recovery from the 152.89 early-month low built higher lows, including the 155.33 higher low, up to the 159.03 swing high. Intervention warnings from Tokyo then forced a rejection there, leaving a lower high against the 160.39 window high and a pullback to the 156.50 swing low, which held the rising trendline just below the 38.2% fib retracement. Price now sits between EMA20 (~157.7) and EMA50 (~157.2) with the 157.85 prior high capping, and ATR(14) near 49 pips is well below the early-month expansion, showing compression between converging trendlines.

Support: 156.50, 155.33

Resistance: 157.85, 159.03, 160.39

What it said to watch

  • H4 close below the 156.50 swing low breaks the rising trendline and exposes the 155.33 higher low
  • Close above the 157.85 prior high reopens the 159.03 swing high and the falling lower-high trendline
  • Wed MoF intervention data and Tankan could materially shift this read
  • US JOLTS Tue and ADP Wed could move yield spreads and test the range edges
