The JPY has been changing direction every month since the low in May. May was a low instead of a seasonal high. and, almost all signals from the seasonal chart you showed have been inversions up to this point. that is, the seasonal has been 180 degrees from the market. highs have been lows and lows highs. 100% wrong on direction.
the October seasonal does hit the market so far. There was a high early this month.
This is why I am USD bearish until the entity can show me something other than inversions. although, truth be told, the JPY is a miniscule part of the actual DX make up.
