USDJPY pair for a long time oscillates around a very important resistance area, which defeated could pave the way for further gain. Considering that after the defeat at the beginning of the month downtrend line market has not yet tested this place from the top (according to the principle of polarity changes) we expect declines even to support around 99.90.
After all, it is worth to pay attention to the current situation on the H1 chart where yesterday price overcame local downtrend line. Today’s declines are re-testing now, mentioned trend line from the top in a place where it coincides with local support 103.75. The rejection of that level could open the way for further growth even in the vicinity of the level of 104.57.
