Turtle Trading System + ATR Trailing Stop

Indicator Description: Turtle ATR Trailing Stop

The **Turtle ATR Trailing Stop** is a technical indicator designed to enhance the classic Turtle Trading System by incorporating a dynamic trailing stop based on the Average True Range (ATR). This indicator is ideal for traders seeking to manage risk and lock in profits on both long and short positions in trending markets.

Key Features:
- Turtle Trading Levels: Calculates the 20-day highest high and lowest low to identify potential breakout points, a core principle of the Turtle Trading System.
- ATR-Based Trailing Stop: Utilizes a trailing stop that adjusts dynamically based on a multiple of the ATR (default multiplier: 2.0), providing a volatility-adjusted exit mechanism.
- Position Flexibility: Supports both long and short positions, with the trailing stop positioned below the highest price for long trades and above the lowest price for short trades.
- Smooth Updates: The trailing stop updates on each bar, ensuring a more responsive adjustment to price movements, rather than only on new highs or lows.
- Reset Mechanism: Automatically resets the trailing stop when the price deviates significantly (configurable threshold, default 0.1%), adapting to major trend reversals.
- Alerts: Includes customizable alerts that trigger when the price reaches the trailing stop level, notifying traders of potential exit points.
- Debugging Tools: Features an on-chart debug table displaying ATR, Close, Highest Price, Lowest Price, Potential Stop, and Trailing Stop values for real-time analysis.

How It Works:
- For **Long Positions**: The trailing stop starts below the initial close price (minus 2*ATR) and moves up as the highest price increases, locking in profits while trailing at a fixed ATR distance.
- For **Short Positions**: The trailing stop starts above the initial close price (plus 2*ATR) and moves down as the lowest price decreases, protecting against upward price movements.
- The stop resets if the price falls (for long) or rises (for short) beyond the set threshold, ensuring adaptability to new market conditions.

Customization:
- Period Settings: Adjust the length for highs/lows (default 20) and ATR period (default 14).
- ATR Multiplier: Modify the distance of the trailing stop (default 2.0).
- Reset Threshold: Fine-tune the percentage at which the stop resets (default 0.1%).
- Position Type: Switch between "Long" and "Short" modes via input settings.

Usage:
Apply this indicator to any chart in TradingView, set your preferred parameters, and monitor the trailing stop line (yellow) alongside the Turtle highs (red) and lows (blue). Use the debug table to validate calculations and set alerts to stay informed of stop triggers.

This indicator combines the trend-following strength of the Turtle System with a flexible, ATR-based stop-loss strategy, making it a powerful tool for both manual and automated trading strategies.
