Daily chart of USDJPY shows that supply dominated last week. If not the Friday session, the sellers would pass a set of 5 bearish days. On Friday, however, there was a chance to recover, which after such strong declines seems necessary. The pin bar that was created that day, is bringing growth on start of new week. You can probably count on a re-test of the lower limit of a broader side trend. Even if the price does not get so high, it seems that you can count on at least the test of the last low from September 8, i.e. around 107.30.
