Hi Alexed, I was looking at a book from the 30s that showed how to base the direction of the economy by the production and order size of domestic pig iron. I would definitely say that Steel, Copper and Aluminum production would still be a leading indicator as to the base economy. These metals are still the core of most businesses IMHO. With all of the head fakes in the other markets I would not be surprised to see one with Metals also. Take Care Alexed! :^)
Good Luck to All! :^) PLAN the TRADE and TRADE the PLAN!
