jpy crosses are good to trade on if you are experience and have good equity. They can be easily scalped to get some quick pips.
Yeah, that's true Jeppy is good for newbies because it always featured with nice swings&frequent trends. But recently after trading for 2 years I switched my focus to exotic pairs such as EUR/TRY, USD/RUB, Hotforex has quite tight spreads on them, around 10 copecks for USD/RUB (Russian cents) so I think it's a good opportunity to profit from RUB highly correlated with oil.
