Hello,
Coins-E seems to have its bid/ask orders flipped for the DOGE_BTC market (the highest bid rate - lowest ask rate is positive!).
If you compare https://www.coins-e.com/exchange/LTC_BTC/ with https://www.coins-e.com/exchange/DOGE_BTC/ you'll see what I mean. I had a close look at the API and even the auto-complete buy/sell javascript automatically fill in the wrong rates by default.
Either that or I'm stupid and goofed. Can anybody confirm this?
