I've been battling back and forth for weeks whether or not to trade just the EURUSD or include all pairs in trading. Thing is i've done best at eurusd and pretty average at the others.Though i put the monthlies of the USD pairs and they pretty much move the same way as the others, so why even bother with pairs that i'm worse at? im probably not being clear here but in my case i want to trade every pair and keep track of the fundamentals of dozens of economies, but i seem to be much better at trading one and knowing its fundamentals well, and still paying attention to general news.
