Fix or improve an existing MT5 Expert Advisor — entries, sessions, risk, trade management, logging, or setup issues.

Starting at $500

Final price depends on what you need built and how clear the rules are. You get a written quote before work starts.

“Starting at” amounts are guides, not checkout prices. Custom quotes are priced after we review the scope. Work starts only after you accept a written quote.

What is included

  • Review of the bug or improvement you reported
  • Work against the repaired behavior agreed in a written quote
  • Testing notes for that repair scope
  • A defect-fix window after delivery as stated in the quote

What is not included

  • A free full code audit treated as finished repair work
  • Guaranteed fixes for compiled-only or undocumented third-party software
  • Full rewrites unless separately quoted
  • Profit or funded-account guarantees

Customer responsibilities

Send complete and accurate rules, examples, files, platform details, and any source materials you have the right to share. Test what we deliver in a safe demo environment before live use.

Revisions: Two reasonable revision rounds limited to matching the written repair quote. No new features or unrelated redesign.

Support: 30-day defect-fix window for reproducible failures to match the agreed repaired behavior.

Terms and cancellation

Policy version: professional-services-v1.0. A project request does not create a development agreement. Work starts only after you accept a written quote and the required payment clears.
