Thanks Pro-Life, Yes, I am aware of the risks and will likely paper trade for about a year before putting any money on the table.
As to your link, it's quite funny as I just bought her book about commodities, "A Trader's First Book on Commodities" by Carley Garner. I haven't finished it yet and I'll likely read it twice before starting paper trades, but thanks for the link for her paper trade site. I didn't know about it.
On a last question, can you suggest where on TDAmeritrade one could find more information about commodity options?
Thanks,
Allen
