Well, here we have the usd/jpy entering a bearish reaction zone, which could lead to price testing the breakout zone again.
We see that the dxy is within a reaction zone maintaining overbought levels, this could trigger a retracement, thus causing the usd to lose a little strength against the jpy
It is important not to go unnoticed that the usd/jpy maintains an overbought level in a period of 4 hours and below, so the price rebound is very close
Having said all of the above, the prudent thing would be to look for sales by confirmation, although if a risk entry was sought, the ideal would be to do it in the upper part of the OB, in both cases (risk or confirmation) good risk management must be maintained.
