Hows the Yen like during opening compared to the Euro? I trade the Euro from around US open to lunch break (EST8:30pm to EST 11-12pm). Would love to include Yen in my trading when I wake up in the morning (i live in Asia). I'm mainly interested in the volatility for scalping. ^_^
I trade the EUR/USD too, and gravitated towards EUR/JPY as well, primarily watching these two pairs. I must say the EUR/JPY pair is more active in the london and new york hours, the range during asian hours is quite limited. (Today is exception )That being said, its a different vehicle in itself. I prefer this to the dollar yen, less noise, and intervention - at least to me.
I trade both AUD/USD and USD/JPY during Asian session. It may show some volatility if some economic release is expected.
