Eric No I don't use commodity data. I depend on
them for stocks, market breadth data and mutual funds.

plus commodity backtesting question
Joe, same here, and I asked QP3 people, its the
limit
to which they support data.
Do you use the commodity data? Im
trying to get
started with developing and backtesting
commodity
strategies. Just looking for anyones thoughts about
data, and
backtesting of contracts using amibroker.
Thanks,
Eric
