You can type any currency pair you want into the trade dropdown. Speaking of which, can anybody else see my BTC/BTC trade? The client makes it a puzzle to set up the trade correctly, but I don't see a reason it shouldn't work.
BTC/BTC? How do you see that market... I can't see that currency pair. Once I select an issuer of base currency, I cannot change the secondary currency other than by selecting a currency pair from the drop-down which does not contain BTC/BTC.
