USD/JPY technical analysis
It's the best time of year to zoom out and look at the long-term charts. USD/JPY is indicative of the broader trend of falling volatility and tighter ranges.
When this breaks, it's not going to be 200-300 pips, it will be much more.
The dollar bears are coming out of hibernation at the moment and you can see the argument for why a break lower would be coming. At some point there is going to be a bear market in equities and money will fly to the yen.
