USDJPY- REVISTING FLASH CRASH LOWS? SPX RISK SENTIMENT RETURNING

Overall multifaceted analysis leading me to short USDJPY

SPX has entered a period of constrained volatility as we could see risk sentiment return to the market?

What does this mean for the so called "flash Crash" that we had in the Yen earlier in the year? Well at 700 Pip rally in less than a quarter is a massive move, but can we sustain that momentum?
