Trailing SL Strategy

The Trailing SL Strategy tool provides a systematic approach to trend-following by using a single, dynamic trailing stop loss to determine market direction and execute immediate position reversals.

Usage

The Usage section describes how the script can be used to capture market trends through automated stop-execution. The strategy operates on a continuous "always-in-the-market" basis; once the price breaches the trailing stop loss line, the current position is closed and a new position in the opposite direction is opened.

Users can choose between three distinct calculation methods for the stop loss:

• Percentage (%): The stop loss is placed at a fixed percentage away from the current price.
• Average True Range (ATR): The stop loss adapts to market volatility, calculated as the ATR multiplied by a specific coefficient.
• Absolute: The stop loss is placed at a fixed price distance from the current price.

For example, a trader looking to capture long-term trends might use the ATR setting to allow for wider stops during volatile periods, while a scalper might prefer a tight Percentage-based stop to exit quickly when momentum shifts.

Details

The strategy logic, originally developed by QuantNomad, is built around the concept of price action relative to a trailing boundary. For long positions, the trailing stop loss is calculated as the low - slVal, but it is designed to only move upward (taking the maximum of the previous SL and the new calculation) to lock in profits. Conversely, for short positions, the stop is calculated as high + slVal and only moves downward (taking the minimum of the previous SL and the new calculation).

When the price crosses the trailing stop line:

1. A reversal signal is generated.
2. The calculation of the stop loss flips to the opposite side of the price.
3. The strategy enters a new trade (Long if price broke above the SL, Short if price broke below).

Settings

The settings are categorized to allow for precise control over the risk management and the backtesting period:

• SL Type: Selects the mathematical foundation for the trailing stop (%, ATR, or Absolute).
• % SL: Defines the percentage distance for the stop loss when "%" is selected.
• ATR Length: Sets the lookback period used to calculate the Average True Range.
• ATR Mult: The multiplier applied to the ATR value to determine the stop distance.
• Absolute SL: Sets a fixed point/price distance for the stop loss.
• Backtesting Range: A group of settings (From Day/Month/Year to To Day/Month/Year) that defines the specific window of historical data where the strategy will execute trades.

FAQ

How does the strategy handle "whipsaws" or sideways markets? Because this is a reversal strategy that is always in a position, sideways markets may result in multiple consecutive stop-outs. Users should adjust the SL Type and values to filter out minor price fluctuations.

Can I use this for alerts without trading? Yes, the script includes visual plots and built-in alert conditions for Long and Short signals that can be used for manual trading or external notifications.
