TrailingFiftyFifty
Download script
This script is designed to automate the management of open trades by dynamically adjusting your "Stop Loss" (the price at which a trade automatically closes to prevent further loss). It uses a logic called "Half-and-Half" trailing, which calculates and moves the stop loss based on a specific percentage of the distance between your entry price and the current market price.
Core Logic Overview
Instead of moving the stop loss by a fixed amount (like 10 pips), this script looks at the progress of the trade. It evaluates the distance between where you entered the trade and where the price is currently moving, then calculates a new stop loss position based on a "coefficient" (a percentage) provided by the user.
How it Works
- Time-Based Execution: The script does not move the stop loss every second. It waits for a specific time frame to complete (e.g., every hour or every 15 minutes). This ensures that the movement is based on "confirmed" price action rather than temporary market fluctuations.
- The Calculation: When a new candle opens, the script calculates the distance from the current price to either your entry price or your existing stop loss (depending on your settings). It then takes a fraction of that distance—determined by your coefficient—and moves the stop loss accordingly.
- Example: If your trade is in profit and you set a 0.5 coefficient, the script will move your stop loss to the halfway point between the current price and your starting point. As the price moves further into profit, the "halfway point" also moves forward, effectively locking in gains.
- Smart Protection: The script is programmed to be cautious. It will only move the stop loss if the new position actually improves your situation (i.e., it moves the stop closer to the profit). It will not move the stop loss in a way that increases your risk.
- Loss Zone Handling: There is an optional setting that allows the script to begin moving the stop loss even while the trade is still in a losing position (between the entry price and the initial stop loss). If turned off, the script primarily focuses on trailing profits.
Key Parameters Explained
- Ticket Number: Allows you to target one specific open trade for this logic to apply to.
- Time Frame: Sets how often the calculation happens (e.g., every 60 minutes).
- Coefficient: Determines the "aggressiveness" of the trail. A higher number moves the stop loss closer to the current price more quickly; a lower number keeps it further back.
- Loss Trailing: A simple toggle to decide if you want the script to manage the stop loss while the trade is underwater or only when it moves into profit.
In summary, this tool acts as an automated safety net that "follows" the market price, moving your exit point forward as the trade succeeds, ensuring that a winning trade doesn't turn into a losing one due to a sudden market reversal.
