Download script
This script is designed to manage trade risk by automatically adjusting the "Stop Loss" price of an open position based on how much profit the trade has accumulated. Unlike a standard trailing stop that moves at a fixed distance, this logic uses a dynamic "staircase" approach.
Core Logic Overview
The script monitors a specific trade and adjusts the safety net (Stop Loss) more aggressively as the price moves in your favor. It operates on three distinct profit zones:
- Zone 1 (Initial): When the trade is in its early stages, it maintains a wide trailing distance.
- Zone 2 (Intermediate): Once the trade reaches a specific profit level, the script "tightens" the safety net, reducing the distance between the current price and the Stop Loss.
- Zone 3 (Advanced): When the trade reaches an even higher profit milestone, the script applies its tightest trailing distance to lock in the majority of the gains.
How it Works Step-by-Step
1. Input Parameters The user defines three key sets of data:
- Distance Levels: Three different distances (how many "points" away from the price the Stop Loss should stay).
- Profit Thresholds: Two specific profit targets that trigger the move from one distance to the next.
2. Validation Before performing any actions, the script checks to ensure that the inputs provided are mathematically logical (e.g., ensuring that the profit levels are higher than the distances and that the trade actually exists). If the settings are incorrect, the script will alert the user and stop execution.
3. Trade Monitoring The script constantly calculates the current profit of the trade relative to your entry price. Depending on where the price currently sits:
- If the profit is low, it selects Distance 1.
- If profit has passed the first threshold but not the second, it selects Distance 2.
- If profit has exceeded the second threshold, it selects Distance 3.
4. Automated Execution The script then calculates where the new Stop Loss should be placed based on the selected distance. It includes logic to handle both "Buy" (Long) and "Sell" (Short) positions:
- For Buy Positions: It ensures the Stop Loss stays below the current price.
- For Sell Positions: It ensures the Stop Loss stays above the current price.
5. Safety & Modification The script will only modify the trade if the new calculated Stop Loss is better than the existing one (i.e., it moves the stop in a way that protects more profit). It also checks against "Stop Levels" (minimum distance requirements set by the broker) to ensure the order modification isn't rejected by the server.
Summary for the User
Think of this as an automated "profit locker." As your trade becomes more successful, the script automatically moves your Stop Loss closer to the current price in stages. This helps protect your gains from sudden market reversals while giving the trade enough "breathing room" during its initial phases.
