The world of finance is often divided between those who believe success comes from innate talent and those who believe it can be taught through rigorous systems. Turtle trading stands as a historic testament to the latter. Originating from a legendary experiment in the 1980s, this trend following methodology has shaped the way modern market participants approach risk management and technical analysis. By understanding the mechanics of turtle trading, investors can learn how to remain disciplined in the face of market volatility and focus on long-term profitability rather than short term noise.
The Origins of the Turtle Trading Experiment
The concept of turtle trading began with a bet between two successful commodities traders, Richard Dennis and William Eckhardt. Dennis believed that anyone could be taught to trade successfully if given a clear set of rules, while Eckhardt argued that trading required an inherent flair. To settle the debate, Dennis recruited a group of novices, famously referred to as the Turtles, after being inspired by a turtle farm he visited in Singapore. His goal was to grow traders just as efficiently as the farm grew its reptiles. These individuals were taught a specific, rule based system and given capital to trade. The experiment was an overwhelming success, proving that a systematic approach to the markets could indeed yield exceptional results.
Understanding Investing vs Trading in the Turtle Framework
When exploring turtle trading, it is vital to distinguish between investing vs trading. In the broader financial landscape, investing is often viewed as a slow and steady marathon focused on fundamental value and long term growth. This aligns with the metaphorical description of turtles in the stock market as buy and hold participants who are unfazed by short term swings.
However, the turtle trading system itself is a sophisticated form of trend following trading. While investors might hold assets for decades based on company health, turtle traders follow the price action. They do not care about the intrinsic value of a commodity or stock; they care about the direction of the trend. This method requires a complete shift in mindset, moving away from owning a business to renting a price movement.
Core Principles of the Turtle Trading Strategy
The turtle trading strategy is built on several pillars that ensure consistency and minimize emotional decision making. These principles are as relevant today as they were decades ago.
Market Selection and Liquidity
Turtles were instructed to trade in highly liquid markets. Liquidity is essential because it allows for easy entry and exit without significant slippage, which is the difference between the expected price of a trade and the actual price executed. The original group focused on commodities, currencies, and bonds, seeking markets that exhibited strong, clear trends.
Position Sizing and Volatility
One of the most revolutionary aspects of the system was how it handled position sizing. Instead of using a fixed amount of capital for every trade, turtles adjusted their position size based on the market’s volatility. They used a measure called N, which represented the 20 day average true range (ATR). This ensured that a trader’s risk remained constant regardless of how volatile a specific market was. By accounting for volatility, the system helped protect against the impulsive nature of greedy risk takers.
The Rules for Entry and Exit
The turtle trading rules are remarkably specific, leaving no room for interpretation. This mechanical nature is what allowed beginners to compete with seasoned professionals.
System 1: The Short Term Entry
The primary entry rule for the short term system was a 20 day breakout. A trader would enter a long position if the price exceeded the high of the preceding 20 days. Conversely, they would enter a short position if the price dropped below the low of the preceding 20 days. This rule ensured that the trader was always participating when a new trend began to form.
System 2: The Long Term Entry
For those looking to capture even larger moves, System 2 utilized a 55 day breakout. This served as a fail safe for when a trader might have missed the initial 20 day signal or if the market was experiencing a particularly strong and prolonged trend. By following these breakouts, traders avoided the herd mentality that often leads to poor investment performance.
Exit Strategies and Risk Management
Entering a trade is only half the battle; knowing when to leave is where the profit is secured. For System 1, the exit was a 10 day low for long positions or a 10 day high for short positions. For System 2, the exit was a 20 day low or high. Additionally, the turtles practiced strict risk management, often using a stop loss order to limit losses to a small percentage of their total capital.
The Role of a Stock Market Advisor in Trend Following
While the turtle trading rules are public, executing them with discipline is challenging. Many modern investors seek the help of a stock market advisor to help them navigate these complexities. An advisor can provide the necessary oversight to ensure that a trader does not succumb to the head in the sand approach of an ostrich, ignoring negative trends until it is too late. They provide the technical watchlists and high liquidity recommendations that are essential for a trend following system to work effectively.
Example of a Turtle Trade in Action
Imagine a scenario where the price of Gold has been fluctuating between 2,300 and 2,400 for several weeks. A turtle trader following System 1 would monitor the 20 day high. If the price of Gold suddenly breaks through 2,410 (the 20 day high), the trader would enter a long position. They would then calculate their position size based on the current volatility (N). If the price continues to rise, they might add to their position. However, as soon as the price drops below the recent 10 day low, the trader exits the position, capturing the meat of the trend while protecting their capital from a reversal.
Conclusion
The turtle trading strategy remains a cornerstone of systematic trading education. It teaches the importance of rules over emotions, the necessity of volatility based position sizing, and the power of trend following. Whether one is a timid chicken avoiding all risk or a cunning wolf looking for market weaknesses, the lessons of the turtles provide a balanced path toward disciplined market participation. By mastering these rules, any dedicated individual can move closer to achieving consistent success in the financial jungles.
