Intraday recovery, early Asia higher highs · RSI 64 · price 157.576
Weekly open gap filled, higher lows off 157.20 into Friday breakdown zone.
Monday's Asia open gapped about 10 pips below the 157.31 friday close from the 157.20 weekly open. Price filled the gap and ran to a 157.68 session high, and the pullback on that Asia leg held 157.53. It is now retesting the 157.60 area, which gave way during Friday's NY sell-off on Katayama's intervention warning, with the 157.77 breakdown point overhead.

Opening gap filled, pullback from 157.68 session high.
Monday Asia opened with a 12-pip gap down at the 157.20 weekly open. It filled the gap to Friday's 157.32 close and ran to a 157.68 session high before stalling, and is now at 157.53, about 31% of the opening leg retraced. The backdrop is Friday's slide to 156.94 on Katayama's 'bold action' jawboning; the rebound is stalling just above UOB's 157.60 pivot, with Friday's prior high at 157.47 the first shelf below.

Friday's slide from 158.84 to 156.94 followed MoF Katayama's 'bold action' warning. The pair reopened about 10 pips lower at the 157.20 open low, then recovered the gap and pushed to a 157.68 session high in thin early Asia trade. Price is now stalling near the 78.6% retracement of Friday's final leg, just under the 157.77 swing high, with RSI(14) near 69.

Monday's Asia open gapped about 12 pips below the 157.32 Friday close. Price filled the gap from the 157.20 Monday low and pushed through the 157.47 breakout level, the neckline of Friday's 156.94/156.97 double bottom. It is now pressing the 38.2% fib of Friday's Katayama-driven decline at 157.67, with RSI(14) near 71 in thin pre-Tokyo liquidity and the 157.77 swing high just above.

It has since settled into a range, with a double bottom at 156.94/156.97 and a run of higher lows. The weekly open gapped down to 157.20, filled Friday's 157.32 close within the hour, and early Asia is now pressing the 157.47–157.49 session high near the 23.6% fib of the Friday decline, with RSI(14) at 59 and price sitting right at EMA50.
