DislikedI thought I share this with you guys. Some are totally aware of this way more than I am . Anyway, as we can see from this table, which is refreshed by Oande weekyl, some time it is not good to trade both EU and AU, sometimes it is fine.
The thing is that EU, AU ang GU do correlate to a degree but not allways and it is difficult to say whether they would do the next week.
A few months ago AU and EU moved on the short term together like real sisters. GU was kind of on her own pretty much all the time.
I hope this is useful for some.
