In the world of stock and hedge funding, does there exist, for instance, a way to gather a tremendous amount of data on the price of wheat from 20 years on the stock exchange (For instance, on Wall Street stock)? In fact, I'd like to treat, statistically, the price of a stock product, but I don't know where we may find out that type of data.
In the James Simons's discussions (A rare interview with the mathematician who cracked Wall Street), Simons explains that "The real thing was to gather a tremendous amount of data -- and we had to get it by hand in the early days. We went down to the Federal Reserve and copied interest rate histories and stuff like that, because it didn't exist on computers." (Time : 11:26), but where is that Federal Reserve?
