使用套接字的 MetaTrader 5 和 Python 集成

Question

我正在尝试使用套接字在 MetaTrader 5 和 Python 之间建立连接。服务器部分用 python 编写，客户端部分用 mql5 编写。客户也是 Expert Advisor，而不是指标。问题是当我同时运行服务器和客户端时，客户端给我“错误4014”。如果有人能帮助我解决这个问题，我非常感激。

 //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

}

Answer 1

您是否尝试过在选项中配置 WebRequest 设置？

配置的路径是工具 -> 选项 -> Expert Advisors -> WbRequest（复选框）。您想要添加 localhost 或 127.0.0.1 以允许连接。

我希望这仍然悬而未决并且有帮助。
