Sideways, higher lows, recovering · RSI 63 · price 158.544

157.55-158.95 range with rising lows off 156.95.

USDJPY has spent two weeks inside a 157.55-158.95 range. Lows have stepped up from the oct low at 156.95 along a rising trendline that held again near 157.70 on Monday. The rejection from the 158.95 swing high came as the broad USD retreated on the AI-led equity pullback, and price has since recovered above both EMAs to retake the 61.8% retracement of that drop. ATR(14) has compressed to roughly 34 pips from 50+ earlier in the window, a coiling profile between the range floor and the 158.75 prior high.

Support: 157.70, 157.55, 156.95

Resistance: 158.75, 158.95, 159.03

What it said to watch

  • H4 close above the 158.95 swing high and 159.03 range top breaks the range; 160 is the intervention-sensitive zone
  • Rejection again at the 158.75 prior high keeps the lower-high sequence from 158.95 intact
  • Close below the rising trendline near 157.70 exposes the 157.55 range floor; a break there reopens the oct low at 156.95
  • Japan National CPI Thu 23:30 UTC and US S&P Global PMIs Fri 13:45 UTC could materially shift this read

Range-bound, rising lows, pressing upper half · RSI 61 · price 158.486

Higher lows since 156.38 inside 157.50–158.95 range.

Since the 156.38 late-September low, USDJPY has printed a sequence of higher lows (156.95, 157.52, 157.55, 157.70) beneath a 158.75–158.95 cap, and the rising-lows line now sits near 157.73. Price has cleared the 158.33 lower high and the 61.8% retrace of the 158.95→157.55 leg, while ATR(14) near 37 pips is well below late-September readings. The H4 pattern is compression into the upper half of the range. The yen has stayed soft despite hawkish BoJ commentary, and USD is steadying after last week's pullback.

Support: 158.33, 157.73, 157.55

Resistance: 158.75, 158.95, 159.03

What it said to watch

  • H4 close above the 158.95 range top opens the 159.03 sept high and the intervention-sensitive 159–160 area
  • Slip back below the 158.33 lower high returns price to mid-range and points to a false break
  • Break of the rising lows near 157.73 and the 157.55 range floor would end the higher-low sequence
  • Japan September core CPI (Thu 23:30 UTC, f/c 2.1%) could materially shift this read
  • Fri US S&P Global PMIs and FOMC next week could drive the rate gap either way

Sideways, momentum neutral · RSI 55 · price 158.242

157.55–158.95 range with lower highs since the spike high.

USD/JPY has held a 157.55–158.95 range for about two weeks since recovering from the 156.38 low. Last week's spike to 158.95 faded straight back to the range low, as the soft-USD tone and a Fed hold that is still well priced outweighed hot US PPI and retail data. Price now sits at the 50% retracement of that drop and just above a flat ema50, with a lower high at 158.35. ATR(14) has compressed to roughly 38 pips, and the EMAs are converged and flat, so the range is tightening rather than trending.

Support: 158.15, 157.55, 156.95

Resistance: 158.35, 158.95

What it said to watch

  • H4 close above the 158.35 lower high reopens the 158.95 spike high, where intervention rhetoric near 159 becomes the main brake
  • Loss of the 157.55 range low, tested three times, exposes the 156.95 swing low
  • Repeated H4 closes below the ema50 at 158.15 would tilt the range structure toward the lower half
  • Japan National CPI (Thu 23:30 UTC) and US S&P Global PMIs (Fri 13:45 UTC) are the main catalysts that could break the compression

Sideways range, rising lows beneath · RSI 52 · price 158.162

Range 157.55–158.95 with higher lows since 156.38.

USDJPY has carved a 157.55 range floor to 158.95 prior high range since the early-October pullback. Lows have risen from 156.38 through the 156.95 swing low to the 157.55 floor, while the range cap near 158.50 has capped most rallies. The spike to 158.95 was rejected as the dollar slipped on fading Fed hike pricing despite hot PPI and retail data, and intervention risk weighed near 159. Price sits about 44% back into that drop, with flat EMA20/EMA50 converged near 158.10–158.15 and ATR(14) compressed to roughly 39 pips from 60+ earlier, consistent with a breakout pending.

Support: 157.55, 156.95

Resistance: 158.50, 158.95

What it said to watch

  • H4 close above the 158.50 range cap reopens the 158.95 prior high, where MoF intervention rhetoric is the cap to monitor
  • Failure to hold the 157.55 range floor breaks the rising-lows trendline and exposes the 156.95 swing low
  • Japan National CPI Thu 22 Oct 23:30 UTC (core f/c 2.1%) could materially shift this read
  • US S&P Global PMIs Fri 23 Oct 13:45 UTC ahead of next week's Fed meeting could rebuild or erase hike pricing

05:02 UTC

Sideways, higher lows under a flat 159 cap · RSI 48 · price 158.079

Higher lows since 156.38, highs capped 158.95-159.03.

Higher-low structure intact since the 156.38 swing low, with the latest higher low at 157.55 holding near the 50-61.8% fib of the 156.38-158.95 advance. Highs keep stalling at the 159 cap: the 158.95 spike on last week's hawkish BoJ chorus was sold back to 157.55 as the dollar softened despite hot US PPI and retail sales. Price is coiling around 158.00 on flat EMA20/EMA50 with ATR(14) near 40 pips, well below early-window readings. The rising lows under a flat top resemble an ascending triangle.

Support: 157.55, 157.36, 156.38

Resistance: 158.50, 158.95, 159.03

What it said to watch

  • H4 close below the 157.55 higher low breaks the rising-lows trendline and exposes the fib 61.8 at 157.36
  • H4 close above the 159 cap and 159.03 window high ends the range read; MoF intervention rhetoric near 159 has capped prior attempts
  • Prior highs at 158.50 are the first test of any recovery inside the range
  • Japan National CPI Thu 22 Oct 23:30 UTC (ex fresh food f/c 2.1%) is the main catalyst for a range break; a loss of 157.55 would put the 156.38 swing low back in view
  • US Initial Claims Thu and S&P PMIs / UoM inflation expectations Fri could shift US yields and test either range edge

01:03 UTC

Sideways, drifting toward range floor · RSI 40 · price 157.734

Three-week range 157.50-158.95 with a lower high.

USD/JPY has rotated inside a 157.50-158.95 band for three weeks. The latest push stalled at 158.95, a lower high under the 159.03 early-window peak, and the rejection has returned price below EMA20 and EMA50 toward the range floor, which held on four tests. The hawkish BoJ chorus is losing traction while the hot US PPI keeps rate differentials supportive, and ATR(14) near 42 pips is compressed against the earlier swings, leaving the range edges as the breakout candidates.

Support: 157.55, 157.22, 156.38

Resistance: 158.25, 158.50, 158.95

What it said to watch

  • H4 close below the 157.50-157.55 range floor breaks the three-week range and exposes the 157.22 swing low, then the 156.38 window low
  • Recovery through the 158.25 prior high and a close above the 158.50 range cap reopens the 158.95 lower high
  • Japan National CPI Thu Oct 22 23:30 UTC could materially shift this read
  • Hormuz/oil headlines at the open and Fri US PMIs could move this read through US yields
