Recently we witnessed a sharp dropped on USDJPY due to BOJ hints of intervene in currency market. However, in fact they just gave hint of intervention and did not specify the plan. In some scenario, many says, it was a move to alter the direction of JPY pairs for sometime. In our view price is likely to move upside strongly after touching our area. We therefore advise you, if you are taking sell entry be extra cautious.
Good luck and trade safe.
