Turtle Trading Strategy@lihexie

This trading strategy is a classic trend-following system known as the Turtle Trading strategy. It enters long on a breakout of a 20-period high and short on a breakdown of a 20-period low. It exits the position when the price reverses and breaks a shorter-term, 10-period channel, or if the initial stop-loss is hit.

To trade this strategy manually :

This strategy has two systems. System 1 is the primary one described below. System 2 is identical but uses a 55-period channel for entries and a 20-period channel for exits. You trade both, but with one special rule: if the last trade on System 1 was a winner, you skip the next System 1 signal.

• Indicators Needed:
  • Donchian Channels (or manually find the highest high/lowest low).
  • Average True Range (ATR) with a 14-period length.
• Settings (System 1):
  • Entry Channel: 20 periods.
  • Exit Channel: 10 periods.
• Position Sizing (The "Unit"): Before entering, calculate your position size, called a "Unit". One Unit = (2% of your account equity) / (2 * current ATR value). All your entries and additions will be in multiples of this Unit size.
• Entry Conditions:
  • Long: Enter with 1 Unit when the price closes above the 20-period Donchian Channel's upper band.
  • Short: Enter with 1 Unit when the price closes below the 20-period Donchian Channel's lower band.
• Stop-Loss:
  • Place your initial stop-loss 2 * ATR away from your entry price. (For a long, it's Entry Price - 2*ATR. For a short, it's Entry Price + 2*ATR).
• Adding to a Position (Pyramiding):
  • If the trade moves in your favor, add another Unit at every 0.5 * ATR interval from your last entry price.
  • You can add a maximum of 3 additional units, for a total position of 4 units.
  • Each time you add a unit, move the stop-loss for the *entire position* up to 2 * ATR away from the newest entry price.
• Exit Conditions:
  • Long Exit: Exit the entire position if the price closes below the 10-period Donchian Channel's lower band.
  • Short Exit: Exit the entire position if the price closes above the 10-period Donchian Channel's upper band.
  • Or, exit if your stop-loss is hit.

The Turtle system is a powerful but purely mechanical strategy. Your edge as a manual trader is adding a layer of discretion to filter out low-quality signals and manage trades more dynamically. Here is a plan to build on its foundation.

• Add a Market Regime Filter. The Turtle strategy bleeds capital in sideways, choppy markets. To fix this, add a long-term trend filter. A simple method is using a 200-period Exponential Moving Average (EMA). Only consider long breakout entries when the price is trading above the 200 EMA, and only take short entries when the price is below it. This single rule helps ensure you are trading in the direction of the dominant, underlying trend and avoids fighting the market.
• Demand Confirmation on Entries. Raw breakouts often fail. Instead of entering the moment the price pierces the 20 or 55-day high, wait for a candle to close decisively beyond that level. More importantly, look for a surge in volume on the breakout candle. A high-volume breakout signals conviction from other traders and dramatically increases the probability of follow-through. A breakout on weak volume is a red flag and a signal you should probably skip.
• Use Dynamic Exit and Profit-Taking. The fixed 10-day low exit can give back a lot of profit. You can improve this by using a more responsive trailing stop like the Chandelier Exit, which is based on ATR and often hugs the price action more tightly. Additionally, before you even enter, identify major historical support and resistance levels on your chart. Plan to take partial profits at these key levels instead of waiting for the system’s mechanical exit signal.
• Be Smarter with Pyramiding. The script adds to positions at fixed ATR intervals. A better approach is to add on pullbacks to key levels. After a breakout, price will often retest the breakout level (old resistance becomes new support). Adding a new unit on a successful, confirmed bounce off this level is a much higher-probability entry than adding blindly just because the price has moved a certain amount.

This strategy is designed for swing or position traders, not day traders. It is a classic trend-following system, meaning it aims to capture substantial profits during major, sustained market moves. The holding period for a single trade can last for weeks or even months, requiring a hands-off approach once a position is established.

This style is best suited for traders who are:

• Patient and disciplined: You must be able to wait for the right conditions to develop, as entry signals can be infrequent. Following the rigid rules for entry, exit, and position sizing is critical.
• Psychologically resilient: Trend-following systems typically have a low win rate. You must be comfortable taking many small, manageable losses while waiting for the handful of large wins that produce the majority of the profits.

• Strategy Type: A classic, mechanical trend-following system designed to capture large market moves over weeks or months.
• How it Works: The strategy enters on price breakouts of a 20 or 55-day high/low. Exits are triggered when the price breaks a shorter-term 10 or 20-day channel against the trend.
• Who it's For: Patient swing and position traders who are disciplined and can psychologically handle a low win rate in exchange for large winning trades.
• How to Use It: It can be fully automated with the script. Alternatively, set alerts on the breakout levels to combine automated signals with manual analysis and execution.
• How to Enhance It: Add a long-term trend filter, like a 200 EMA, to trade only in the direction of the main trend. Confirm entry signals with a surge in volume on the breakout candle.
• Risk Management: Position size is calculated using ATR to normalize risk per trade. The system adds to winning trades (pyramids) and trails the stop-loss to protect profits as the position grows.
