MetaTrader 5 and Python integration using socket

[ajaxx]

Hi there,

I am trying to established connection between MetaTrader 5 and Python using socket. Server part written in python and client part written in mql5. also client is Expert Advisor not a indicator. problem is when i run both server and client ,client gives me "error 4014".

I'm very thankful if someone can help me to solve this problem.

//this is python server code
 import socket

 serv = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 serv.bind(('127.0.0.1', 9090))
 serv.listen(1)

 while True:
     conn, addr = serv.accept()
     print('client connected to :', addr)
     conn.close()

//This is mql5 client code

Hi ajaxx,

Have you tried configure WebRequest setting in option?

The path to the config is Tools -> Options -> Expert advisors -> WbRequest (checkbox). You want to add localhost, or 127.0.0.1 to allow connection.

I hope this is still pending and it helps.

Best
