Converting a .ex4 file to .ex5 is done through the online service ex4toex5.com.
No source code required — just the compiled executable. Here is the full process from upload to delivery.
Go to the homepage of ex4toex5.com. No registration or software installation is required — the service runs entirely in your browser.
On the homepage, click the Convert button to start the process. A file selection dialog will open.
Choose your file with the .ex4 extension from your computer and upload it. The source code (.mq4) is not required — only the compiled executable file. Decompilation is not needed either.
After upload, the service will automatically analyse the file and determine whether conversion is possible. This may take a few minutes. The result will be displayed on the page.
If the analysis detects any limitations — such as non-standard code protection — you will be notified before any payment is required.
If the analysis is successful, enter the email address where the converted .ex5 file will be delivered. Double-check the address — re-delivery requires a support request.
The service fee is 50 USDT. Available payment methods are shown on the page after you enter your email address. Once payment is confirmed, your order is queued for processing automatically.
Once conversion is complete, the .ex5 file will be sent to the address you provided. Most orders are processed within two business days.
If the email hasn't arrived, check your Spam folder. If the file doesn't load in MT5, contact support with a description of the error shown in the Journal tab of your terminal.
