ICBIT just rolled out a major site redesign, so the trouble you experienced may have been related to that. As I speculated in the original article, however, a major source of risk for the strategy I outlined remains the exchange itself.

I'm afraid I don't have any other numbers to share with regard to highs or lows or averages, but I do think the going rates for futures are worth paying attention to every so often; sometimes the market is willing to be fairly accommodating.
