Yen cross system

So I’m relatively new to forex and would like to find a solid system that would work for yen cross pairs. Anyone have any ideas or knowledge on the subject? Any input would be much appreciated.

Short the Yen and short it hard! What type of trading are you looking to do? Scalping, intra-day, Swing, Position?

Well I’m new so scalping seems like the most fun but I really don’t have time for it as I work 8 to 5. I usually have the best luck day or swing trading so I would like a system for that. Just curious why do you say short the yen?
