The USDJPY fumbled up and down in most of the US session, but a crack lower was strong enough to fall below the double-bottom and 61.8% of the move up from the June low near 157.364. The low-price extended down to 157.15 which was the same low going back to June 17 when the price bottomed against the rising 100-day moving average. The inability to break below that level and the subsequent move back above the 61.8% retracement, gave buyers ago had to push back higher.
What next?
