I am planning to collect US commodity prices for at least 200 items
daily (day-before prices) for research purposes, and data and results
may be available free of charge to subscribers. It seems that CME and
NYMEX provide that data to a set of brokers, sellers, investors, and
data distributors. The questions is: What websites offer for free
commodity prices via web services, xml, or just text format that can
be legally parsed and stored on my end, and shared data and results
with others under this free-of-charge subscription basis? |
