websocket MT4

[Krzysztof Tadeusz Kanacki]

Can anyone help unravel this problem. I am trying to communicate python with MT4. The problem is that even when I close/deactivate the python code, something is constantly coming in at the MT4 input. I don't know what it is. Are they some buffers or other things?

The code looks like below : 

<lib_websockets.mqh> I took it from https://github.com/mikha-dev/mt4-websockets/blob/master/MQL4/Include/lib_websockets.mqh

Maybe someone has something more reliable/proven to work. I would be happy to try it out. 

I tried a 'dedicated pipe', but it consumed huge amounts of resources, the computer stopped.

Thanks in advance for your help and best regards
