So I go to Tradhill and check their Market data, and I see this:
Highest Bid: 4.2000 Lowest Ask: 4.0999
Last I checked, if one person is bidding 4.2 and another is asking 4.0999, then a trade should already have been executed. Any insight on why this happens?
Also, on Mt Gox, I go to the Trade page, and they list similarly strange numbers: Lowest Ask Price: 4.03354, Highest Bid Price: 4.50000
Perhaps they are listing the high trade instead of the highest bid?
