Authorized EX4 to MQ4 recovery: what legitimate owners should know

EX4 to MQ4 recovery is a sensitive service because compiled MetaTrader files may contain intellectual property, trading logic, licensing code, and commercial strategy. A professional recovery workflow starts with proof of ownership, not with anonymous uploads or unrealistic promises.

Short answer: if the EX4 file represents your own lost MQ4 source code, we can review the project, verify authorization, assess feasibility, and recover or reconstruct what is legally and technically possible.

When EX4 to MQ4 recovery is legitimate

A recovery case is appropriate when the customer is the original developer, the business owner of the software, or an authorized maintainer acting for the rights holder. Common examples include a deleted MQ4 file, a lost development computer, an incomplete handover from a contractor, or an older Expert Advisor that still runs but cannot be maintained.

What ownership proof can look like

What a professional team should not do

A legitimate recovery service should not remove license systems, bypass copy protection, clone commercial products, or decompile third-party software without authorization. These are not quality signals; they are risk signals. Clear refusal criteria protect the customer, the rights holder, and the recovery team.

Why exact recovery cannot be guaranteed

EX4 files are compiled artifacts, not neatly archived MQ4 source projects. Feasibility can depend on the MetaTrader build, compiler behavior, file condition, available supporting files, and how much original project context remains. A serious provider should explain these limits before starting billable work.

What happens after recovery

The goal is maintainable MQ4, not just a raw output. Where possible, recovered code can be organized, reviewed, commented, and prepared for future maintenance. Some projects are better handled as a clean rewrite when reconstruction is not feasible or not appropriate.
