Spécifications

I have an already functioning auto-trading Expert Advisor (EA) that requires debugging and issue resolution. The EA is currently encountering a few critical bugs that must be fixed. The developer should be able to:

  1. Analyze and understand the EA’s trading logic and functionalities.
  2. Identify the root cause of the bugs and explain why they occur.
  3. Propose and implement a reliable fix for these issues.
  4. Ensure stability and proper functionality after the fixes are applied.

If the job is done well, I would like to establish a long-term working relationship for future bug fixes and feature additions.

Issues to Fix:

  1. Infinite SL/TP Modifications & EA Removal from Chart:

    • The EA modifies Stop Loss (SL) and Take Profit (TP) an infinite number of times, causing erratic behavior.
    • After some time, the EA removes itself from the chart unexpectedly.
    • Investigate and resolve the cause of this behavior.

  2. Account-Level SL/TP Overriding Individual Position SL/TP:

    • The EA has two types of SL/TP settings:
      • Per-position SL/TP: Applied to individual trades.
      • Account-level SL/TP: Trading should completely stop when the account reaches a certain balance.
    • The issue: The account SL/TP seems to be overriding individual position SL/TP settings, which is unintended.
    • Fix the logic so that both systems function independently as expected.

Additional Information:

  • The EA consists of approximately 1,000 lines of code, ~400 lines relevant to the problem 

Requirements:

  • Strong expertise in MQL5 and MetaTrader 5 development.
  • Experience debugging and fixing EA issues related to trade execution, SL/TP modifications, and account management.
  • Ability to clearly communicate the root cause of bugs and the solutions implemented.
  • Willingness to provide support for potential future updates and fixes.

Deliverables:

  • Fixed EA with all identified bugs resolved.
  • Testing confirmation to ensure stability and proper functionality.

If you’re confident in your ability to solve these issues, please send your proposal, including your experience with similar projects and estimated completion time.

Looking forward to working with an experienced MQL5 developer!
