Off-topic, but how did you get into commodities? Do you trade independently, or for a large firm?
After about 5 years of being on the webmaster team of a technology megacorp I was offered a chance to join great energy trading company in a sort of developer/analyst/bridge/free-agent role. Since then, that company has traded hands a couple of times and currently belongs to a large European bank that wanted into the US power market.
Email's in my profile if you want to chat.
