The USDJPY decline from 108.57 could be the beginning of larger wave 3 (as mentioned).
However, it is not yet safe to enter from the short side. We’ll wait for the drop from 108.57 to unfold in 5 waves or for the advance from 104.99 to unfold correctively (in what could be a small wave ii of 3). Potential resistance is in the 106.30/107.10 zone.
