Yes, When Compression in Volatility ends - it results in explosive move.
USD/JPY saw a massive compression in volatility (the triangle pattern) between January 2014 and July 2014. I wrote about this couple of times that one should wait for breakout from this compression in Volatility.
Now just see what happened post breakout in volatility. JPY has made a big move from 102 to 107 in just one and a half month. A breakout from compression in volatility is always a rewarding trade
