The BoJ price stability is firm but at wider tolerance. Perhaps, this is caused by the carry trading activity by the JPY-carry traders. The wider tolerance causes possible risk in interdays trading but lower risk on short term target zone trading and lowest risk on medium term target zone trading. However, in term consistency very consistent on short and medium term. The pair is underway to 107.00 in short term and could be proceeds to 102.00 in medium term.
