21:03 UTC

Uptrend, extension pausing · RSI 66 · price 157.432

Higher highs and higher lows since the 152.886 low; consolidating under the week high.

Price has carved a clean sequence of higher highs and higher lows off the 152.886 base, with the BoJ's dovishly-delivered hike to 1.25% driving the impulse leg from the 156 handle to 158.053 before a reported rate check dragged it back under the 157 pivot. The last six bars are a tight consolidation between 156.60 and 157.53, holding above both EMA20 and EMA50, with ATR(14) near 52 pips after the post-BoJ expansion. The 158.05 week high is the immediate cap, with 158.42 flagged as the intervention band above it.

Support: 156.60, 155.33

Resistance: 158.05, 158.42

What it said to watch

  • H4 close above 158.05 week high opens the path toward the 158.42 intervention zone and the psych 160 handle
  • Loss of the 157 pivot and a close below the 156.60 swing low breaks the higher-low sequence
  • US S&P Global PMIs Wed 13:45 UTC are the week's only top-tier data and could reset this consolidation
  • Unscheduled MoF/BoJ rate-check or intervention headlines remain the sharpest single-name risk to the read, with 155.33 the next prior low beneath

17:03 UTC

Uptrend, momentum consolidating near highs · RSI 66 · price 157.476

Higher highs and higher lows since the 152.89 base; sideways compression under 158.05.

USDJPY has rebuilt a clean higher-high / higher-low sequence off the 152.89 base, with the dovish BoJ hike and the hawkish Fed dot plot widening the rate gap and driving the recovery through 156.58. The last five bars have compressed into a tight flag between 156.58 and 158.05 in holiday-thin Tokyo liquidity, with ATR(14) around 57 pips and price holding above both the EMA20 and the EMA50 near 155.70. Supply capped the advance at 158.05 last week, leaving the 158.42 resist band as the next reference above.

Support: 156.58, 155.70

Resistance: 158.05, 158.42, 160.00

What it said to watch

  • H4 close above 158.05 prior high extends the impulse toward the 158.42 resist band and, above that, the 160.00 psych level
  • Loss of the 156.58 swing low breaks the higher-low sequence and shifts the read back into the 155.70 ema50 area
  • US flash PMIs Wed 13:45 UTC and any further BoJ/MoF rate-check or intervention headlines could materially reset this structure

13:02 UTC

Uptrend, pausing after impulse · RSI 59 · price 157.206

Higher highs and higher lows since the 152.89 base; tight consolidation under the week high.

Price has carved a clean sequence of higher highs and higher lows off the 152.89 base, with the final leg accelerating into 158.05 as the dovish BoJ delivery met last week's hawkish FOMC repricing. The last four bars are compressed in a 70-pip band above the 156.58 swing low, a shallow consolidation that keeps the impulse structure intact with price above both EMA20 and EMA50. ATR(14) near 57 pips is elevated versus the mid-window grind, so the expansion phase has not yet faded.

Support: 156.58, 155.33, 154.83

Resistance: 158.05, 158.85, 160.20

What it said to watch

  • Sustained trade above the 158.05 week high opens the path toward the 158.85 prior pivot and the 160.20 range high
  • An H4 close below the 156.58 swing low would break the consolidation and put the 155.33 higher low back in play
  • Loss of 154.83 prior low would end the higher-low sequence
  • US flash PMIs Wed 13:45 UTC and intervention headlines as 160 nears could materially shift this read

11:44 UTC

Uptrend, pausing below the prior high · RSI 63 · price 157.211

Higher highs and higher lows since the 152.89 base; tight consolidation under 158.05.

Price has rebuilt a clean higher-low sequence from the 152.89 base, with the dovishly delivered BoJ hike to 1.25% and the hawkish Fed dot plot driving the impulse from the 155 area to 158.05 before the reported rate check pulled it back under 157. EMA20 sits above EMA50 and both are below price, while the last five bars have compressed into a 70-pip band between 156.60 and 157.31 — ATR(14) near 58 pips is fading off the impulse peak, consistent with consolidation rather than exhaustion. Supply capped the advance twice at 158.05/157.90, and that prior high is the pivot that defines whether the multi-day advance extends or stalls.

Support: 156.60, 155.70

Resistance: 158.05, 158.42, 160.00

What it said to watch

  • H4 close above 158.05 (prior high) opens the path toward the 158.42 mof zone, where intervention headline risk is highest
  • Failure to hold 156.60 (swing low) breaks the higher-low sequence and puts the ema50 near 155.70 back in play
  • US S&P Global flash PMIs Wed 23 Sep 13:45 UTC are the week's main data risk to this consolidation
  • Unscheduled MoF/BoJ verbal escalation between 158.00 and 160.00 (psych) could gap the structure

09:03 UTC

Uptrend off the 152.89 base, momentum steady · RSI 62 · price 157.256

Higher highs and higher lows since 152.89; consolidating under the fri high.

USDJPY has carved a clean sequence of higher lows since the 152.89 base, and the hawkish Fed dot plot paired with a dovish-delivered BoJ hike powered the impulse leg to the fri high at 158.06 before a pullback into 156.58. Price is now consolidating in a tight 156.57-157.28 band above EMA20 at 156.42 and well clear of EMA50, with ATR(14) near 57 pips after the expansion into Friday's spike. The 156.58 swing low and the 158.06 fri high define the near-term container; the prior low at 155.33 is the first structural break point below.

Support: 156.58, 156.42, 155.33

Resistance: 158.06, 158.42

What it said to watch

  • A close above the fri high at 158.06 extends the higher-high sequence toward the 158.42 interv zone, where official rate-check headlines become a two-way risk
  • Loss of the 156.58 swing low and EMA20 at 156.42 would break the consolidation and expose the prior low at 155.33
  • US S&P Global flash PMIs Wed 13:45 UTC are the next scheduled catalyst capable of resetting this range

05:03 UTC

Uptrend, momentum pausing after impulse · RSI 58 · price 156.986

Higher highs and higher lows since the 152.89 low; consolidating below the 158.06 recent high.

After the mid-window slide from 160.39 to 152.89, price has built a clean sequence of higher lows and higher highs, culminating in the impulse to the 158.06 recent high — the recovery has now retraced roughly two-thirds of that decline, with the hawkish Fed dot revisions and a dovishly-delivered BoJ hike to 1.25% behind the leg. The last four bars have gone quiet in a 156.58-157.11 band above a rising EMA20 and EMA50, a flag-style pause rather than distribution, while ATR(14) near 58 pips is off the expansion peaks of the 158.06 push. RSI near 58 leaves room in either direction and the 156.58 swing low is the first structural marker beneath price.

Support: 156.58, 155.33, 154.83

Resistance: 158.06, 160.39

What it said to watch

  • H4 close above the 158.06 recent high would extend the higher-high sequence and open the 160.39 range high area
  • Loss of the 156.58 swing low breaks the flag and puts the 155.33 prior low back in play
  • A close back under the EMA50 near 154.83 would invalidate the higher-low structure
  • S&P Global Flash PMIs Wed 13:45 UTC and the Fed speaker cluster Tue are the nearest scheduled risks to this read
  • Unscheduled MoF intervention headlines near 158.00+ could sharply compress the range

01:03 UTC

Recovery uptrend off the 152.89 base · RSI 64 · price 157.014

Higher highs and higher lows, consolidating below the 158.05 week high.

USDJPY has rebuilt a clean sequence of higher lows since the 152.89 base, breaking out of the 155.00-156.40 multi-day range and tagging 158.05 before pulling back to retest the 156.50 pivot low area, where demand stepped in. The dovishly-delivered BoJ hike to 1.25% and a firm dollar post-Fed are the drivers behind the leg up, with price now holding above both EMA20 and EMA50 after the bullish cross. ATR(14) near 66 pips shows expansion rather than compression, consistent with an extending swing rather than a coiling one.

Support: 156.50, 155.33

Resistance: 158.05, 159.01, 160.00

What it said to watch

  • Acceptance above the 158.05 week high opens the path toward 159.01 swing high and the 160.00 psych level
  • Loss of the 156.50 pivot low would break the higher-low sequence and put 155.33 swing low back in play
  • Wed S&P Global US PMIs (Services f/c 56) are the main scheduled risk to this structure in the next sessions
