Despite the decline, there are signals on the USDJPY chart indicating a possible upcoming change in direction.
The medium-term movement vector of USDJPY indicates the formation of a Triple Three wave structure. Now the formation of the wave [xx] is completed and the beginning of an upward movement within the wave [z] is expected.
At a lower-degree wave structure, the formation of a triple three is noted. Now the price is in the wave (z), which completes this formation. This wave is expected to end in the near future. After that the current price trend may change.
To summarize, at the moment the USDJPY chart is maintaining a downward movement vector. However, the corrective wave is in the final stage of formation.
In this situation, long positions are prioritized.
