Turtle Trading System Overview
- Turtle Trading System Overview
The Turtle Trading System is a renowned trend-following system developed by Richard Dennis and William Eckhardt in the 1980s. It gained notoriety through the "Turtle Experiment," where Dennis sought to prove that anyone could become a successful trader with the right rules and discipline, regardless of their background or experience. This article provides a comprehensive overview of the system, its principles, rules, and implementation, geared towards beginner traders. We will delve into the core mechanics, risk management approaches, and historical context that make the Turtle Trading System a cornerstone of modern technical analysis. Understanding this system can provide a solid foundation for anyone looking to explore systematic trading strategies.
The Turtle Experiment
In 1983, Richard Dennis, a highly successful commodity trader, became convinced that trading success was more about following a defined system than innate talent. He believed he could take individuals with little to no trading experience and, through rigorous training and a specific set of rules, transform them into profitable traders. He advertised for "Turtle" trainees, offering to fund their education and trading capital.
He received over a hundred applicants and ultimately selected 14 individuals, known as the "Original Turtles." These individuals came from diverse backgrounds – academics, athletes, and even a professional gambler. The training program was intense, focusing on Dennis's and Eckhardt’s trading rules, primarily based on trend-following principles. The Turtles were given real money to trade and were closely monitored.
The results were remarkable. Within a relatively short period, many of the Turtles achieved substantial profits, proving Dennis’s hypothesis. This experiment solidified the idea that a rules-based, systematic approach to trading could be highly effective. The system’s success wasn’t based on predicting market direction, but rather on capitalizing on established trends. Technical Analysis plays a crucial role in identifying these trends.
Core Principles of the Turtle Trading System
The Turtle Trading System is built upon several core principles:
- **Trend Following:** The fundamental belief is that trends, once established, tend to persist. The system aims to identify and ride these trends for maximum profit. This is closely related to the concept of Market Trend.
- **Risk Management:** Protecting capital is paramount. The system incorporates strict rules for position sizing and stop-loss orders to limit potential losses. Risk Management is a vital component.
- **Objectivity:** The system is designed to remove emotional decision-making from the trading process. Rules are pre-defined and followed consistently, regardless of market conditions or personal biases.
- **Systematic Approach:** Every trading decision is based on the rules of the system, eliminating discretionary judgments.
- **Diversification:** Trading multiple markets simultaneously to reduce overall risk. This spreads risk across different asset classes.
- **Patience:** Waiting for the right signals and avoiding impulsive trades. Discipline is key.
The Trading Rules: A Detailed Breakdown
The Turtle Trading System consists of a series of rules categorized into different areas: market selection, entry rules, exit rules, and risk management. The rules are often presented with varying degrees of detail, but the core concepts remain consistent.
1. Market Selection:
The Turtles traded a variety of markets including commodities (soybeans, wheat, corn, oats, crude oil, natural gas, silver, gold, copper), currencies (Japanese Yen, German Marks, British Pound, Swiss Franc), and Treasury Bonds. The system was designed to be adaptable to different markets. Understanding Market Dynamics is essential for applying the system effectively.
2. Entry Rules:
These rules define when to enter a trade. There are two primary entry methods:
- **Breakout Trading (The Channel Breakout):** This is the most commonly associated entry rule. The Turtles looked for 10-day and 20-day trading ranges (high minus low). A buy entry was triggered when the price broke above the 20-day high, and a sell entry was triggered when the price broke below the 20-day low. The 10-day range was used as a confirming filter. The price must also be above the 10-day high for a buy and below the 10-day low for a sell. This utilizes Support and Resistance levels.
- **Retracement Trading:** This involved entering a trade after a significant price move, anticipating a continuation of the trend. The rules for retracement trading were more complex and less frequently used by the Turtles.
3. Exit Rules:
These rules define when to exit a trade.
- **Profit Target (Reward):** Typically, the initial profit target was set at twice the initial risk (described in the Risk Management section). This is a 2:1 risk-reward ratio.
- **Trailing Stop Loss:** A trailing stop-loss order was used to lock in profits as the trend continued. The trailing stop was initially set a certain number of ticks (the smallest price movement) below the highest price reached after entry for long trades and above the lowest price reached after entry for short trades. The trail was then adjusted as the price moved in a favorable direction. This utilizes Stop-Loss Orders to protect profits.
- **Time Stops:** If a trade did not reach its profit target within a specified period (usually a few days), it was exited regardless of the price. This prevented capital from being tied up in losing trades for too long.
4. Risk Management:
This is arguably the most critical component of the Turtle Trading System.
- **Position Sizing:** The Turtles used a fixed fractional position sizing rule. They risked a fixed percentage of their capital on each trade, typically 1-2%. For example, if a trader had $100,000 and risked 2%, the maximum loss on any single trade would be $2,000. This involves calculating Position Size.
- **Stop-Loss Orders:** A stop-loss order was placed immediately after entering a trade. The initial stop-loss level was determined based on the volatility of the market and was typically placed below the recent swing low for long trades and above the recent swing high for short trades. Understanding Volatility is crucial for setting appropriate stop-loss levels.
- **Diversification:** The Turtles traded multiple markets simultaneously, allocating a portion of their capital to each market. This reduced the impact of any single market's performance on their overall portfolio.
Technical Indicators Used by the Turtles
While the core of the Turtle Trading System relies on price action and breakout rules, the Turtles also used a few technical indicators to confirm signals and refine their entries and exits.
- **Donchian Channels:** These channels, formed by the highest high and lowest low over a specified period (typically 20 days), were used to identify trading ranges and breakout points. This is a key element of the Donchian Channel strategy.
- **Moving Averages:** While not central to the core rules, some Turtles used moving averages to help identify the overall trend direction. A simple Moving Average can provide trend confirmation.
- **Relative Strength Index (RSI):** Some Turtles used the RSI to identify potential overbought or oversold conditions, although this was not a primary rule. RSI is a momentum indicator.
- **MACD (Moving Average Convergence Divergence):** Similar to RSI, the MACD was used by some Turtles for confirmation, but was not a core rule. MACD is a trend-following momentum indicator.
Adapting the System to Modern Markets
The Turtle Trading System, while historically successful, requires adaptation to modern market conditions.
- **Volatility Adjustments:** The fixed percentage risk rule may need to be adjusted based on the volatility of the market. Higher volatility may require a smaller position size.
- **Slippage and Commissions:** Modern trading involves slippage (the difference between the expected price and the actual price) and commissions, which were less significant in the 1980s. These costs need to be factored into the risk management calculations.
- **High-Frequency Trading (HFT):** The presence of HFT algorithms can lead to false breakouts. Using filters or confirmation signals can help mitigate this risk.
- **Backtesting and Optimization:** Backtesting the system on historical data and optimizing the parameters can improve its performance. Backtesting is a crucial step in strategy development.
- **Automated Trading:** The rules-based nature of the Turtle Trading System makes it well-suited for automated trading using trading bots. Algorithmic Trading allows for precise execution of the system's rules.
Common Mistakes to Avoid
- **Ignoring the Rules:** The system's success depends on strict adherence to the rules. Deviating from the rules based on personal opinions or emotions will likely lead to losses.
- **Over-Leveraging:** Using excessive leverage can amplify both profits and losses. Stick to the recommended position sizing rules.
- **Not Diversifying:** Concentrating capital in a single market increases risk. Diversify across multiple markets.
- **Impatience:** Waiting for the right signals is crucial. Avoid impulsive trades.
- **Failing to Adapt:** Market conditions change over time. Regularly review and adapt the system to maintain its effectiveness.
