I will make small fixes to MT5 and MQL5

With MT5 and MQL5,

“I just want to change this part slightly.”
“I want to add an input parameter.”
“I want to change a shortcut key.”
“I want to add a simple condition.”

These are the small fixes we handle.

This service is for those who don’t need a major development project, but find it difficult to modify MQL5 themselves.

What is covered by the base fee

For one MQ5 file, one minor modification is the baseline.

For example,

・Addition or modification of input parameters
・Changes to display text or display position
・Change of shortcut keys
・Addition of a simple conditional check
・Small behavioral changes
・Minor fixes for compilation errors・Minor fixes for compilation errors

etc.

The base fee includes

・Review of the modification
・Modification of MQL5 code
・Compilation check
・Modified MQ5 file
・EX5 file
・One minor modification

Included.

Please consult before purchase

Because the amount of work required varies greatly depending on the modification, please let us know in advance

“How is it currently functioning, and what exactly do you want to change?”

via message.

If you have MQ5 files, error screens, or images showing the current behavior, it makes verification smoother.

We will review the content and let you know whether it can be addressed within the base fee or if additional options are required.

Contents that cannot be handled or require separate consultation

・Restoring sources from an EX5 file
・Major EA logic changes
・Large-scale modifications spanning multiple files
・External API integration
・Creating a new EA from scratch

are not covered by the base fee.

Also, please prepare MQ5 source code that you have the rights to use and modify.

With over 25 years as a software engineer, I have been involved in development since 2019 with MQL4, and subsequently using MQL5 for MT5 tool development and verification.

Please feel free to contact us for small questions like“I just want to change this one spot.”

FAQ

With the basic fee of 8,000 yen, to what extent can changes be made?

This is based on a single minor modification for one MQ5 file. It envisions changes to input items, changes to display positions, changes to shortcut keys, and small additional conditions.

Can I consult with you before purchasing?

Yes. Because the workload varies depending on the corrections, we recommend consulting before purchase. Please briefly inform us of the “current operation” and “how you want to change it.”

There is only an EX5 file, but can it be fixed?

Cannot do it. The MQ5 source code is required for the fix. We do not provide a method to recover the source code from EX5.

Can you also fix/modify the EA?

If the change is minor, I will check the content. Major changes to trading logic, addition of money management, and large-scale EA revisions are not covered by the base fee.

Could you also fix the error?

I will check the contents for minor compilation errors. Depending on the number of errors and the size of the code, there may be additional charges or it may be outside the scope of support.
