So, is it safe to say that if we have a discrepancy in price between 2 commodities relative to their price history, AND there is no long term fundamental shift for that price change, there is a strong probability that the history of relative price will reassert itself?
I do not have long term data of commodity prices. Who would you recommend?
I use paritech for data, they have commodity data going back to 1979 for many commodites, and I use metastock for charts, but any provider that has long term data will do.
