Trillion is not realistic. If one is large AND behaving aggressively in the markets, one or two things will occur: 1) F.B.I. -U.S. Justice Department investigation. If they don't get you, they will get you to be less aggressive. See Warren Buffett. Buffett was Indicted for Illegal Market Manipulation in 1960's. Buffett since Indictment trades less aggressively. 2) They will change the rules. About nine or ten years ago, no more trading gold on margin. Mid-1930's, only can short on an uptick.
Btw., start with $10,000. Plow all wins back in. Seven wins in a row betting all one has, one will be a millionaire. Over 90% chance of losing.
