The so-called "don't ask where the hero comes from".

The suicide of his mother made Bruce coffler's childhood more unfortunate than the average. What is more than surprising is that his initial transaction principal was $3000, even from personal credit cards (10000 foreign exchange merchants opposed borrowing money or investing through overdraft credit cards).
Bruce coffler started buying soybean futures contracts, and a few months later, the money grew to $45000. However, a failed transaction lost more than half of his money in a flash. After feeling panicked, he began to realize the importance of "risk management".
"As long as there is an event that disrupts my mood and world outlook, I close all positions associated with that event."
Cruz coffler started his career at commonites Corporation. The company offers a wide range of product transactions, including corn, cocoa powder, and, of course, foreign exchange. During the six years of work, cruise coffler managed investment funds increased an average of 87 per cent a year, with outstanding performance. Commonites Corporation was later acquired by Goldman Sachs. Cruise coffler left office and founded his own company, Caxton, in 1983.
Asked about the secret of success, cruise coffler said: "first of all, I can predict what the world may be changing in the future and really believe that these changes will happen one day. I predict that soybean prices will double, and one dollar can only be converted to 100 yen. Second, even under heavy pressure, I can still keep my mind and abide by the principles. "
In addition, there was Steven Cohen, the first top trader who was "unskilled," whose story was also wonderful, known as "Michael Jordan in the trading world.".

Steven Cohen, before entering the trading world, was obsessed with poker games, which was gambling. He was born in a middle-class family and in high school he was addicted to poker. But he was not addicted to gambling. When it comes to remembering the poker game, Steven Cohen still believes that his success in the financial arena is due to the fact that poker teaches him how to take risks.
Steven Cohen's first deal was $1000, from his own tuition. After graduating at 22, he won the position of junior trader in gruntal & Co, a small investment bank on Wall Street, and earned $8000 on his first day of work, and has been earning about $100000 a day since then, and has been very popular on Wall Street soon.
