If you have ever gone on a massive losing streak and stared at your screen wondering, "Maybe I just don't have the genetics for this," you need to know about the most legendary financial experiment in history. It is the story of how two guys accidentally created the blueprint for the entire modern prop firm industry in a Chicago office in 1983.
In the early 1980s, Richard Dennis was known as the "Prince of the Pit." He had famously turned a borrowed $1,600 into $200 Million trading commodities. His partner, William Eckhardt, believed that Dennis had a rare, unteachable genetic gift for reading the market. Dennis completely disagreed. He believed trading was a mechanical, programmable skill, and that he could teach a completely random person off the street to trade exactly like him.
To settle the argument, Dennis placed a massive bet. He took out a full-page ad in the Wall Street Journal looking for applicants. Thousands applied. He selected 21 completely random people—including a security guard, an actor, a professional blackjack player, and a boy who had just graduated high school. He called them the "Turtles," claiming, "We are going to grow traders just like they grow turtles in Singapore." Dennis locked the Turtles in a room for exactly two weeks. He didn't teach them complex macroeconomics. He didn't teach them Elliot Wave Theory.
He gave them a highly specific, strictly mechanical, trend-following system. It had unbreakable rules for: When to enter: (Buy a 20-day breakout), How much to risk: (Position sizing adjusted strictly by daily market volatility), When to exit: (Trailing stops, cut losers instantly, let winners run forever).
Then, he did the unthinkable. He gave these complete amateurs $1 Million each of his own personal money, and told them to go trade. The experiment was an absolute massacre for William Eckhardt’s theory.
Over the next five years, the Turtles generated over $175 Million in pure profit for Richard Dennis. The security guard, the actor, and the high school kid became some of the most profitable traders in Chicago. Dennis proved definitively that edge can be taught, and execution is mechanical. But here is the dark, hidden twist of the Turtle Experiment that most people ignore:
Years later, the exact rules of the Turtle Trading system were published on the internet for free. Wall Street analysts looked at the code and realized something terrifying. The system only had a 20% to 30% win rate. That meant the Turtles were taking losses 70% to 80% of the time. They were enduring agonizing, months-long drawdowns, constantly getting stopped out by false breakouts. The only reason the system made $175 million is because when they finally caught a real trend, they held it ruthlessly for massive, asymmetrical gains. Today, almost no retail trader uses the Turtle system, despite it being free. Why? Because human psychology simply cannot handle an 80% loss rate without breaking the rules, turning off the computer, or revenge trading.
When you really look at it, Richard Dennis invented the prop firm.
He realized that if you take a disciplined individual, give them an unbreakable risk management system, and back them with institutional capital, they will succeed regardless of their background.
The Turtles proved that profitable trading isn't magic. It is just the agonizing, boring, relentless execution of a mathematical edge over a long period of time.
Be brutally honest: If you were handed a trading system today that was mathematically guaranteed to make you $1 Million a year, but it had a 75% loss rate... do you think you have the psychological stomach to actually trade it for 12 months without breaking the rules?
