Pure MQL5 MQTT 5 client for MT5 - pre-release, looking for testers

 
Hello all,

I’ve published a pre-release pure MQL5 MQTT 5 client for MetaTrader 5 and I’m looking for people willing to test it and give feedback:


The goal is to make MQTT integration from MQL5 easier for messaging, automation, and external system connectivity.

Fair warning: this project is also heavily vibe coded, so that is exactly why I want more eyes on it before calling anything stable. It has tests, examples, and validation work behind it, but real usage feedback will be much more valuable than my own local confidence.

If anyone tries it, I’d be especially interested in feedback on:

- broker compatibility
- publish / subscribe behaviour
- reconnect handling
- TLS setups
- API usability
- anything unclear, awkward, or broken
- If you test it, please share your MT5 build, broker, whether you used TLS, and what worked or failed.

Even brief feedback is useful.

Thanks to anyone who takes a look.
