I believe Eric's point was a little off, anyway. The bank at Monte Carlo was broken using exactly the method which he was attempting to discredit.
A man went to the casino with several suitcases full of money and proceeded to play roulette using the progressive betting strategy. Eventually he broke the bank. That's when casinos started imposing house limits on the tables. I don't think this story is apocryphal.
In that case, please provide the time, place, and location -- also provide references to original sources so that we can look it up ourselves. Anyone who believes martingales work is invited to try simulating them by computer. You will find that they aren't effective.
I don't think the commodity exchanges have the same sort of limits set up.
You don't know anything about the commodities market, then. There are limits on how large a contract position you can hold, and they are there specifically to prevent attempts at market corners. Perry
