Hi Daniel – I’m not really a commodities trader sort of person, but here is what I know. I believe that the CS futures are traded on the chicago mercantile exchange (or, maybe CBOT, but I think Merc). So, any full service broker should be able to put in a trade through either their own house or an affiliated agent with a seat on the exchange. I don’t think it is anything exotic. Apparenetly trading is very thin, but looking back on its short history it has “forcast” actual CS index levels pretty well.
