According to i286 ticker, ask sum is approaching 60k coins. Is that accurate or is the API screwed up again?
Does that page add up asks on multiple exchanges? I just did it manually with MtGox, Bitstamp and BTC-E and got at least 69k. On MtGox, it's 33k right now.
i286 has been wrong IMO since the 2nd correction from the china news. If it is doing a combined sum from all the exchanges then good, but then again that's not good putting it on a page along side metrics for gox only data.
www.blockchained.com order book 15 days chart is on the money I believe, it agrees with the summary here
