21:02 UTC
Downtrend, range broken lower · RSI 30 · price 156.883
Lower highs from 158.95; range floor at 157.50 broken.
USD/JPY held a 157.50–158.95 range for about two weeks, with lower highs at 158.95, 158.60 and 158.39 before JPY strength on risk-off and softer UST yields broke the range floor this week. Price sits just above the 156.69 swing low, below both EMAs with EMA20 crossing under EMA50. ATR(14) has expanded to about 37 pips after the range-phase compression, and the 38.2% retracement of the 158.95–156.69 leg at 157.55 lines up with the broken range floor.
Support: 156.69, 156.38
Resistance: 157.50, 158.60, 158.95
What it said to watch
An H4 close back above the 157.50 range floor would turn the break into a false break
Failure to hold the 156.69 swing low exposes the late-Sep low at 156.38
Japan core CPI at 23:30 UTC (f/c 2.1%): a print at or below 2.0% risks a snap back into the old range
A reclaim of the 158.60 lower high would undo the lower-highs sequence toward the 158.95 range top
US flash PMIs Fri 13:45 UTC and next week's BoJ/Fed could materially shift this read
17:02 UTC
Turning lower after range break · RSI 33 · price 157.14
157.50-159.00 range floor broken; lower highs at 158.95 and 158.60.
USD/JPY spent roughly two weeks inside a 157.50-159.00 band. It made lower highs at 158.95 and then the 158.60 lower high, before breaking the range floor today. The move came as JPY outperformed on risk-off and falling UST yields, and price is now below both EMAs with EMA20 rolling under EMA50. ATR(14) has expanded to about 37 pips from the low-20s compression inside the range, and the swing low at 156.69 sits just above the 156.38 window low from late September.
Support: 156.69, 156.38
Resistance: 157.50, 157.87, 158.60
What it said to watch
Japan national CPI tonight (core f/c 2.1%) could materially shift this read; a sub-2% print raises the odds of a retest of the 157.50 range floor
An H4 close back above the 157.50 range floor would turn the break into a false break and reopen the old range
The 61.8% fib at 157.87 and the 158.60 lower high cap any rebound; holding below them keeps the lower-high sequence intact
A failure to hold the 156.69 swing low exposes the 156.38 window low; US flash PMIs Friday and Fed/BoJ next week add event risk
13:02 UTC
Downtrend resuming after a multi-week range · RSI 30 · price 157.001
Lower highs since 158.95; range floor at 157.55 broken.
USDJPY spent about two weeks capped by lower highs at 158.95, 158.60 and 158.34, with the 157.55 range floor holding each dip. Softer US yields and hawkish BoJ talk then broke the floor. The last two bars pushed to a new low at 156.69 on the widest ranges in a fortnight. ATR(14) is expanding out of the compression, EMA20 has rolled below the EMA50 near 158.05, and RSI near 30 shows stretched downside momentum, with the early-window prior low at 156.38 the next visible reference.
Support: 156.69, 156.38
Resistance: 157.55, 158.05, 158.60
What it said to watch
H4 close back above the 157.55 range floor would turn the break into a false break and reopen the old range
Failure to hold the 156.69 new low exposes the 156.38 prior low
Japan national core CPI at 23:30 UTC (f/c 2.1%) could materially shift this read; a sub-2% print risks a snap back into the range
Fri US S&P PMIs and UoM inflation expectations; a hot print could lift yields and test the ema50 near 158.05
Lower highs trendline from 158.95 remains intact unless price clears the 158.60 lower high
Lower highs from 158.95; 157.50–158.95 range floor broken.
USDJPY spent most of the window inside a 157.50–158.95 range, defending the floor four times, before the latest bar broke through to a 156.82 break low. Lower US yields after Tuesday's housing misses and hawkish BoJ messaging drove the JPY bid. Price now trades below both EMAs with lower highs since the 158.95 range high. ATR(14) has expanded to about 36 pips from earlier compression, and the 157.52 range floor now sits overhead as the first test of whether the break holds.
Support: 156.82, 156.38
Resistance: 157.52, 157.88, 158.95
What it said to watch
H4 close back above the 157.52 range floor would recast the move as a false break
Failure to hold the 156.82 break low exposes the 156.38 swing low from late September
Recovery through the 50% fib at 157.88 and the lower-highs line would neutralise the breakdown
Japan core CPI at 23:30 UTC (f/c 2.1%) could materially shift this read; a miss below 2% risks a retest of 157.52
US Initial Jobless Claims 12:30 UTC and Friday PMIs ahead of next week's FOMC and BoJ
Two-week range 157.55–158.95, lower highs pressing on a flat floor.
Since the rebound from the 156.38 window low, USDJPY has held a two-week band between the 157.55 range floor and the 158.95 range top. Highs have stepped lower to the 158.60 prior high and then the 158.35 lower high, compressing into a descending-triangle shape. ATR(14) is near 31 pips, roughly half the early-window reading. The latest bar dipped to 157.59 and closed back below both EMAs near the 50% rally fib, as softer US yields after the housing misses keep the dollar contained.
Support: 157.55, 156.94, 156.38
Resistance: 158.35, 158.60, 158.95
What it said to watch
H4 close below the 157.55 range floor ends the consolidation and exposes the 156.94 swing low
Close above the 158.35 lower high breaks the descending-highs sequence and reopens the 158.60 prior high
Japan Sept core CPI at 23:30 UTC (f/c 2.1%) could break the compression; intervention talk near the 158.95 range top has capped rallies
US flash PMIs Fri 13:45 UTC and next week's FOMC/BoJ could shift the range read
Lower highs from 158.95, higher lows from 157.55 inside the 157.50–158.95 range.
USDJPY has been held in a 157.50–158.95 range for about two weeks. Since the 158.95 swing high the pair has printed a lower high at 158.60. Higher lows at 157.55, 157.70 and 157.84 form a rising support line, and the two edges are squeezing price into a narrowing triangle around 158.15. ATR(14) has compressed to roughly 27 pips from 60–100 pips at the start of the window, and EMA20 and EMA50 are flat and intertwined. That fits a market balancing softer US housing data against BoJ tightening talk and intervention risk near 159.00. Price is sitting between the 38.2% and 50% levels of the 158.95→157.55 fib, and the 158.40 cap zone has turned back the last two rallies.
Support: 157.84, 157.52
Resistance: 158.40, 158.60, 158.95
What it said to watch
An H4 close below the 157.84 swing low breaks the rising support line and exposes the 157.52 range floor
A break below the 157.52 range floor would end the two-week range and the higher-low sequence
A close above the 158.60 lower high clears the 61.8% fib and the 158.40 cap zone, putting the 158.95 swing high back in play
Japan national CPI on Thu at 23:30 UTC (core f/c 2.1%) is the most likely trigger for the compressed triangle to resolve
US flash PMIs on Fri at 13:45 UTC; a hot print could test the lower-highs line, while the 158.95–159.00 area carries intervention risk
