A simple set of rules that allowed 13 ordinary people to achieve an average annual return of over 100% in four years.

In the history of finance, few have demonstrated their views in such a dramatic manner as Richard Dennis. This legendary figure in futures not only turned $400 into $200 million, but also made a famous bet with his partner William Eckhardt, firmly believing that trading ability is not a gift but a skill that can be taught.

This bet gave rise to the most famous trading experiment in financial history—"The Turtle Trading Program," proving that with the right rules and discipline, even beginners can succeed in the market.

Run errands from the trading hall to "Trading Prince"

Richard Dennis was born in Chicago in January 1949 and started working as a runner at the Chicago Exchange at the age of 17. Unlike many people of that era, he did not have a prominent background or higher education; his university was the trading floor—where every day was a battle of life and death.

His earliest trading capital was only 1,600 dollars borrowed from his family, of which 400 dollars served as his initial trading funds. This insignificant beginning led to one of Wall Street's most legendary wealth growth stories—he turned that 400 dollars into over 200 million dollars in profits.

In the 1970s to 1980s, Dennis was known as the "Prince of the Trading Floor." His success did not come from mysterious intuition or insider information, but rather from a profound understanding of market principles and strict discipline.

Turtle Experiment: A Disruptive Gamble on Tradition

In 1983, a famous debate erupted between Dennis and his partner William Eckhardt. Dennis believed that great traders could be cultivated through training, while Eckhardt thought that talent was more important. To resolve this disagreement, they decided to conduct an experiment.

They selected 13 trainees from over 1,000 applicants (different sources indicate a discrepancy between 13 and more than 20 people), and provided them with two weeks of training, imparting a complete trading system. These trainees come from diverse backgrounds with almost no trading experience, and were dubbed "turtles" by the media—metaphorically referring to them as farmed sea turtles that are trained and then released back into the ocean market.

The experimental results are shocking: over the subsequent four years, the sea turtles achieved an average annual return rate of over 80% and even more than 100% based on these trading rules. Among them, the most successful student, Curtis Faith, even earned over 30 million dollars in profit for Dennis.

The Four Pillars of the Turtle Trading Rules

The core of the Turtle Trading System is a set of strict rules that can be summarized into four key aspects:

1. Go with the flow
The core of the Turtle Trading Rules is trend following—buying assets that break through new highs and selling assets that fall below new lows. This is in stark contrast to the traditional "buy low, sell high" mentality. It acknowledges that the market often lacks a clear direction for most of the time, but once a trend is established, it tends to last for a considerable period.
2. Technical analysis for navigation
Turtles use a dual time frame - a 20-day breakout (short term) and a 55-day breakout (long term) as the basis for judging trends. They do not speculate on market movements but rather react to price changes, maintaining a humble attitude of "not knowing what will happen in the future."
3. Contrarian Market Psychology
Dennis once said: "Under normal circumstances, he would follow the mainstream market trends for buying and selling, but he has already closed his position based on his intuition before the automated trading system issued a closing signal." This reveals that systematic trading still requires a certain degree of flexibility, but it must strictly adhere to predetermined rules.
4. Risk control is the lifeline
This is the most critical part of the turtle rule. Specifically includes:
· Position size control: Use a money management formula to control the size of each trade, combined with the ATR (Average True Range) indicator to manage the capital allocation for each trade.
· Diversified Investment: Cross-asset (commodities, currencies, bonds, indices, etc.) investment to reduce single market risk.
· Firm Stop Loss: The risk level of any trade must not exceed 2% of the account funds, and a firm stop loss must be implemented when the price moves unfavorably.

Revelations and Warnings: The Contemporary Significance of the Turtle Rule

1. Discipline is greater than talent
Dennis's greatest contribution is not the hundreds of millions he earned, but the proof of the replicability of trading success. The Turtle Experiment demonstrated that with the right rules and discipline, even novices can outperform market experts.
2. The Value of Systematic Decision-Making
The turtle rule helps traders avoid emotional decisions and overcome the psychological traps of greed and fear. It teaches us to think from a probabilistic perspective rather than being fixated on the success or failure of a single trade.
3. Principle of Simplicity
Dennis's system "find the trend, adjust positions appropriately to follow the trend, and quickly cut losses"—seems simple, but executing it requires great discipline. Many trading platforms today have overly complicated this process, thereby losing the essence of the original system.
4. The Philosophy of Risk First
The core spirit of the Turtle Trading Rules is: protecting capital is more important than making profits. Through strict risk control, even with a low win rate, one can achieve exceptional returns by relying on a few large profit opportunities.

Conclusion

Richard Dennis summarized his trading philosophy in his 2015 publication "Richard Dennis Trading Method": "First, trade in the direction of the trend; the market must show a reliable trend as a prerequisite; second, stick to your principles; third, regardless of the analytical system used as a basis for buying and selling, you must follow the direction of the market."

Although the Turtle Trading Rules may need to be adjusted and optimized for today's market environment, their core principles—trend following, risk control, and disciplined execution—still hold eternal value.

There is no guaranteed holy grail for success in the market, but a strict adherence to a set of rules, along with excellent risk management and ironclad discipline, can significantly increase the probability of long-term success.

In a market filled with various "trading stars" and short-term noise, the greatest legacy left by Dennis may be a simple thought: the success of trading is not a mysterious art, but a skill that can be mastered through systematic methods—this viewpoint has fundamentally changed countless people's understanding of financial markets.
