WinSock – library MetaTrader 4

WinSock is a windows network interface that descented from TCP/IP Berkley Sockets, and is the default network interface for TCP/IP. The sockets lie on the session layer (OSI/5). The attached code is an operational example of windows sockets and the included library, although easily expandable, is in a basic form and not a full winsock implemenation. The advantage of the library and code presented is that it’s written completely in mql4 without any use of external dll helper.

The WinSock.mqh is the library and should be placed in your include folder

The wsockserv.mq4 is a winsock echo server blocking mode example that should be put in your scripts folder

The wsockclnt.mq4 is a winsock client example that should be put in your scripts folder

Both server and client support the TCP (connection oriented) and UDP (connectionless) protocols.

To run the example attach the server to a MT4 terminal chart, and then attach the client to another chart in the same or any other MT4 terminal even in a different computer. If you use a different computer for the client take care to specify in server_addr the ip address of the computer that executes the server script. The client/server examples are adopted from the code presented here.
