Downtrend after range breakdown, rebound attempts stalling · RSI 36 · price 156.90
Lower highs out of a 157.55-158.95 range, broke the range floor, holding a minor low above the 5-week low.
USDJPY spent most of the window in a 157.55-158.95 range, carving lower highs from 158.95 to the 158.60 lower high. It then broke the range floor this week and fell to a 5-week low at 156.08 as haven JPY demand and slipping yields pressured crowded USD longs. Price now sits below both EMAs with EMA20 crossed under EMA50, and ATR(14) has roughly doubled to ~50 pips from the range regime. Rebounds have capped at the 157.16 bounce high, near the 38.2% fib, while a minor low at 156.31 is holding above the prior trough.
Support: 156.31, 156.08, 155.50
Resistance: 157.16, 157.55, 158.60
What it said to watch
H4 close back above the 157.55 range floor, which aligns with the 61.8% fib, would negate the range-break read
Failure to hold the 156.31 minor low and the 156.08 5-week low exposes the 155.50 psych level
A break above the 157.16 bounce high would put the 157.55 range floor back in play
The lower-highs trendline from 158.95 caps the broader structure while it holds
Fed decision Wed Oct 28 18:00 UTC: a guidance-free hold or a hawkish December signal could materially shift this read
Tokyo CPI Thu 23:30 UTC and the BoJ decision Fri ~03:00 UTC are the JPY-side swing risks

Downtrend after range break, bounce stalling · RSI 34 · price 156.864
Two-week range broken lower, lower highs below 157.16.
USDJPY spent two weeks in a 157.55–158.95 range, with a lower high at 158.60. It broke the range floor this week as risk-off flows and falling US yields drove a flush to the 156.08 swing low. The rebound stalled at the 157.16 bounce high, near the 38.2–50% retracement of the drop. Price sits below both EMAs after a bearish EMA20/50 cross, and ATR has expanded to around 46 pips from a compressed range regime.

Resistance: 157.16, 157.55, 158.60
What it said to watch
Today's US flash PMIs at 13:45 UTC could materially shift this read
H4 close back above the 157.55 range floor would turn the break into a false break
Loss of the 156.08 swing low extends the lower-low sequence toward the 156.00/155.50 area
H4 closes below the 156.38 prior low leave the 156.08 swing low as the next reference
Rejection under the 157.16 bounce high keeps the lower-highs structure intact
Next week's BoJ decision (Oct 30) and FOMC are the main multi-day event risk

Downtrend after range breakdown, early rebound · RSI 35 · price 156.911
Three-week 157.50–158.95 range broken lower; lower highs since 158.95.
USDJPY spent most of the window boxed between the 157.50–157.60 range floor and 158.95, with a run of lower highs since the 158.95 peak. This week's yen haven bid, backed by firm JPY CPI and BoJ hike bets against a soft dollar, broke that floor and swept below the early-month prior low at 156.38 to a 156.08 month low. The rebound has stalled just under the 157.00 round number and the 38.2% fib near 157.17, with EMA20 now below EMA50 and ATR(14) expanding from about 30 to the mid-40s in pips.
Support: 156.38, 156.08
Resistance: 157.00, 157.17, 157.60
What it said to watch
H4 close back above the 157.60 range floor would neutralise the breakdown and put price back inside the old range
Failure to hold 156.38 prior low, then a break of the 156.08 month low, would confirm a fresh lower low
Rejection at 157.00 round number / fib 38.2 at 157.17 keeps the lower highs sequence intact
US flash PMIs (13:45 UTC) and UoM inflation expectations (14:00 UTC) today could materially shift this read
BoJ decision on Oct 30 and next week's Fed are the dominant catalysts for the range-break follow-through

Downtrend after range break, ATR expanding · RSI 34 · price 156.924
Range floor broken; lower highs from 158.95, fresh low at 156.08.
USD/JPY held a 157.50–158.95 range for most of the window, with lower highs from 158.95 to 158.60 and then 158.34. The range floor gave way this week as risk-off flows and firmer BoJ hike bets lifted the yen, and the drop ran to a 156.08 swing low, under the 156.38 prior low from early in the window. ATR(14) has expanded to around 44 pips and EMA20 has crossed below EMA50, while the latest bar recovered from 156.23 toward the 38.2% retracement of the 158.60–156.08 drop near 157.04.
Support: 156.38, 156.08
Resistance: 157.50, 158.34, 158.95
What it said to watch
An H4 close back above the 157.50 range floor would undercut the break and put price back inside the old range
Failure to hold the 156.38 prior low and a break of the 156.08 swing low would extend the lower-low sequence
A move above the 158.34 lower high and the lower highs line would break the descending swing structure; the 158.95 range high is the top of the old range
US flash S&P Global PMIs at 13:45 UTC and UoM inflation expectations at 14:00 UTC today could shift USD pricing
BoJ decision and Outlook Report on Oct 30 (~03:00 UTC), with the Fed due next week, could materially reset this read

Downtrend, range break extending · RSI 28 · price 156.445
Lower highs from 158.95, range floor 157.50 broken.
USD/JPY spent roughly two weeks in a 157.50–158.95 range, setting lower highs from the 158.95 range high, then broke the 157.50 range floor. The drop came on Thursday's risk-off tone, lower US yields and firmer BoJ hike pricing. Price is now pressing the window low near 156.38, below both EMAs, with ATR expanding out of the prior compression and RSI near 28 in oversold territory.
Support: 156.375, 156.00
Resistance: 157.37, 157.50, 158.946
What it said to watch
An H4 close back above the 157.50 range floor would flag a false break and a return into the prior range
A rebound that stalls at the fib 38.2 near 157.37 would keep the lower-highs structure from the range high intact
Sustained trade below the 156.38 window low exposes the 156.00 round number
US flash PMIs on Fri at 13:45 UTC: a strong print could slow the decline
The BoJ decision on Oct 29–30 could materially shift this read
