The markets widget shows all the trading pairs available on the platform. We are always working to add more options as we add new currencies to the site. 

Clicking on a specific pair will load this pair specifically for each other widget as well.

You have the option to just show the crypto only pairs by clicking on "Crypto" or the ones involving a trade into a fiat currency by clicking on "Fiat". You can click the stars to the left of the pair to add it to your favourites which will appear in a list when you click on "Fav.". You can see the whole list again by clicking on "All". You can also check our trading pairs for which we are offering a staggering zero fees by clicking on "No Fees".
