near as I can figure, the usd/jpy is trading with the stock markets somewhat, and is a sign risk is more acceptable, when they do this more money is going into stocks and not bonds which will cause the usd/chf to drop and eur/usd to rise due to their negative correlation. I've been trading this for the last couple weeks and been doing pretty good. this is just a generalization and there are always lots of other factors at play, but watch the stock market and watch usd/jpy, usd/chf and eur/usd at the same time
