That's because I always look @ best buy order, and there are none at the moment. This is just general error message, will be fixed in the future.

I was using last trade price earlier but that was confusing - with low trade volume and such big spread when someone buys 0.1 OFF for 10k satoshi for fun you can't treat 10k like price at which you can sell 1000 OFF
