[Colonel Flagg]

Damn straight. Yes, you can make a killing, but you can lose everything and then some very quickly.

They run commercials like that on the radio: "You can make a fortune - buy futures in heating oil; for as little as a thousand dollars, you could make up to 50,000 if the price of heating oil increases this winter only 50 cents per gallon" - what they don't say, is that if the price goes down 10 cents, you lose 10,000 dollars in addition to the thousand you already spent. You need a strong stomach and resources to play this game effectively.
