This statement outlines the desired functionality for an Expert Advisor (EA) for trading, specifically in managing open trades. Here is a breakdown of the key points:

1. **EA Management**: The EA should manage open trades based on specific criteria.

2. **Closing Winning Trades**: If a winning trade reaches a certain percentage of profit (denoted as \(X\% \)), the EA should automatically close that trade.

3. **Partial Closing of Opposite Trades**: When the winning trade is closed, the EA should also partially close another open trade that is in the opposite direction. The goal is to achieve a net profit for both trades that equals a specified amount (e.g., 10 USD).

4. **Input Parameters**: The trades to be managed by the EA will be identified through input data, which could include:
   - **Ticket Number**: A unique identifier for each trade.
   - **Magic Number**: A unique identifier assigned to trades by the EA.
   - **Comment**: A text identifier added to the trades.

The main objectives of this EA are to automate the management of trades to ensure profits are secured and to handle trades in a coordinated manner to achieve a predefined profit target.
