How to Send Requests via MQL5 VPS?

[Huseyin Furkan Ozturk]

Hello everyone,

I’m currently running my EA on MQL5 VPS and I’d like to understand how (or if) it’s possible to send external requests from the VPS environment.

Specifically:

• Can the EA make WebRequest() calls while hosted on MQL5 VPS?

• If not, is there any workaround or alternative method to communicate with external servers?

• Are there any limitations or settings that must be adjusted before migration?

I’ve read that MQL5 VPS restricts some functions for security reasons, but I couldn’t find a clear explanation in the documentation.

Any clarification or example setup would be really appreciated.
Thanks in advance!
