For questions related to currencies or foreign exchange markets. Ideally, this tag should be accompanied by specific currency tags under discussion.
This tag is to be used for any question related to rates between 2 pairs of currencies. If the question is generic, only this tag is sufficient. If its specific for a pair of currencies, ideally both the currency tags should also be used.
I was trying to tag some questions when I couldn't decide on which to use. What is the difference between these two tags?
