Range after uptrend, compressing · RSI 50 · price 158.237
Rising lows under a flat 158.50 cap.
After the rally to the 159.03 swing high, the pullback found a floor at the 156.38 swing low. Since then the pair has printed rising lows at 156.95, 157.44 and 157.52 against a flat range top near 158.50, which has been tested three times. Price is holding between the 61.8% and 78.6% retracement of that pullback, above both EMAs. ATR(14) has compressed to around 37 pips, well below the 50-60 pip readings seen during the swing legs. USD is easing off its highs as yields cool, while US-Japan intervention risk keeps capping the topside.
Support: 157.50, 156.95, 156.38
Resistance: 158.50, 159.03
What it said to watch
H4 close above the 158.50 range top opens the path to the 159.03 swing high
Break of the rising-lows trendline and a close below the 157.50 range low exposes the 156.95 higher low, then the 156.38 swing low
UoM sentiment and 1y/5y inflation expectations at 14:00 UTC could break the compression either way
Japan-US meeting on the IMF sidelines next week carries intervention-rhetoric risk near the range top
09:03 UTC
Range after uptrend, momentum flat · RSI 51 · price 158.334
Higher lows since 156.38 under a flat 158.45-158.51 cap.
Since the 159.03 swing high, USDJPY has carved higher lows at 156.38 (range floor), 156.95 (swing low) and 157.52 (higher low), while the 158.45-158.51 range high has capped two pushes. The result is an ascending-triangle-like squeeze sitting between the 61.8% and 78.6% retracement of the 159.03-156.38 decline. ATR(14) has compressed to roughly 37 pips from 50+ earlier in the window as USD fades from 18-month highs on easing yields, while wide rate gaps keep the yen soft and intervention risk caps the topside.
Support: 157.52, 156.95, 156.38
Resistance: 158.51, 159.03
What it said to watch
H4 close above the 158.51 range high opens the path to the 159.03 swing high, where intervention rhetoric is likely to intensify
A break of the 157.52 higher low and the rising support line would end the higher-low sequence and expose the 156.95 swing low
Loss of the 156.38 range floor would turn the multi-week structure lower
UoM inflation expectations today 14:00 UTC and US CPI next week could break the ATR compression
Lower highs from 159.03, higher lows from 156.38; compressing range.
Since the 159.03 swing high, USDJPY has printed lower highs at 158.45 and 158.51 and higher lows off the 156.38 range floor and 156.95 prior low. That leaves price coiling around 158.00, which is the 61.8% fib retracement of the 159.03-156.38 drop, with EMA20 and EMA50 flat and stacked tight. The hawkish FOMC minutes lifted the pair toward the 158.51 prior high, but the move reversed as US yields eased and intervention risk near 158.50-158.70 capped it. ATR(14) has compressed to roughly 37 pips, consistent with a converging range.
Support: 157.52, 156.95, 156.38
Resistance: 158.51, 159.03
What it said to watch
H4 close above the 158.51 prior high breaks the lower-high trendline and exposes the 159.03 swing high
Failure to hold the 157.52 swing low shifts focus to the 156.95 prior low and the 156.38 range floor
UoM sentiment and inflation expectations at 14:00 UTC today could break the compression via US yields
Intervention rhetoric as price approaches 158.50+ could cap any test of the prior high
01:02 UTC
Sideways after rejection at 159.03, compressing · RSI 50 · price 158.009
Lower highs from 159.03 against higher lows from 156.38; contracting range.
Since the 159.03 range top, USDJPY has printed a lower high at 158.51 while the lows step up from the 156.38 range floor through the 156.95 swing low to the 157.52 higher low. That leaves a contracting wedge around 158.00, which sits at the 61.8% retracement of the 159.03-156.38 swing. ATR(14) has eased to the mid-30s in pips, and price is pinned between a flattening EMA20 overhead and EMA50 below. Yen relief from US yields retreating on Trump's Iran no-strike pledge is offsetting the hawkish Fed path, and intervention sensitivity near 158.50-159 keeps supply capping the topside.
Support: 157.52, 156.95, 156.38
Resistance: 158.51, 159.03
What it said to watch
H4 close above the 158.51 lower high breaks the falling trendline and puts the 159.03 range top back in play
Failure to hold the 157.52 higher low breaks the rising trendline and exposes the 156.95 swing low, then the 156.38 range floor
Fri 14:00 UTC UoM sentiment and inflation expectations, plus Fed's Collins, could resolve the compression via US yields
Iran/oil headlines eroding the no-strike pledge would shift the yield driver behind the range
