Professional EX4 to MQ4 recovery for verified owners
Built for developers, companies, agencies, and traders who lost their own MQ4 source code and still have the compiled EX4. We verify ownership first, define the legal scope, and then recover or reconstruct what is technically possible.
Expert Advisor recovery
Bring a verified legacy EA back into maintainable MQL4 form for fixes, audits, and updates.
Indicator reconstruction
Assess indicators and scripts, document limitations, and recover usable project structure where possible.
Cleanup and handover
Recovered MQ4 can be organized, commented, and prepared for controlled maintenance by your team.
Ownership proof
We only decompile EX4 files you own or are authorized to recover
Before any EX4 to MQ4 recovery work starts, you must show that the project is yours or that the rights holder authorized the recovery. This protects your intellectual property and keeps the service focused on legitimate source-code restoration.
Project evidence
Original order records, development history, vendor invoices, repository traces, or matching project assets.
Authorization
If you are not the original author, provide written permission from the rights holder.
Confidentiality
We can sign an NDA before files or strategy details are exchanged.
Feasibility gate
No promise is made before the EX4 file, build context, and legal scope are reviewed.
Process
A controlled recovery workflow from EX4 to maintainable MQ4
Initial request
Describe the EA, indicator, or script, the MetaTrader context, and why you own the project.
Proof review
We verify ownership or authorization before asking for sensitive files or strategy details.
Feasibility analysis
The EX4 build context and recovery potential are assessed, then scope and limitations are explained.
MQ4 delivery
Recovered or reconstructed MQ4 is delivered with practical notes for maintenance and next steps.
Compliance
Top-tier recovery without the gray-zone behavior
We do not crack third-party products, remove licensing, bypass copy protection, or work around access restrictions. The offer is simple: if the EX4 represents your lost source code, we help you recover it professionally.

FAQ
Answers before you share any files
What does the $499 launch offer include?
The $499 offer covers one eligible authorized EX4 to MQ4 decompilation request after ownership verification. If the case needs heavy cleanup, rewrite work, or unusual recovery handling, that extra scope is quoted separately before work begins.
Can I see verified client reviews?
Yes, once a client approves public publication. Recovery work is confidential by default, so we do not expose names, strategy details, star ratings, or review markup without explicit client approval.
Can you decompile my EX4 file back to MQ4?
We can assess EX4 to MQ4 recovery only when you prove that the file is your property or that you are authorized to recover it. Technical feasibility depends on the file, build context, and protection state.
What ownership proof do you need?
Useful proof can include development history, matching project assets, invoices, repository traces, purchase or commissioning records, business ownership documents, or written authorization from the rights holder.
Do you work on third-party Expert Advisors or indicators?
No. We do not work on third-party software unless you can provide clear authorization from the rights holder.
Do you bypass copy protection or licensing systems?
No. We do not remove license controls, bypass copy protection, or work around access restrictions. The service is for legitimate recovery of your own lost source code.
Is exact MQ4 recovery guaranteed?
No. Exact source recovery cannot be guaranteed. Our team first reviews feasibility and then reconstructs what can be legally and technically recovered.
Is my trading logic confidential?
Yes. Project details are handled confidentially. An NDA can be agreed before file exchange or technical analysis.
