MT4 Client Library

A lightweight Go client library for interacting with a MetaTrader 4 (MT4) trading server over TCP.

Example Usage

import "go.popov.link/metatrader4/mt4"

client := mt4.NewClient("127.0.0.1", 443,
    mt4.WithDialTimeout(3*time.Second),
    mt4.WithAutoClose(true),
)
ctx := context.Background()
params := map[string]string{
    "login":    "55555",
    "password": "_some_password_",
}
res, err := client.Execute(ctx, "WWAPUSER", params)

The Execute method sends a raw MT4 command. Parameters are encoded using base64 and Windows-1251. Use WithAutoClose(false) if you want to reuse the connection manually via client.Close().

Options

• WithDialTimeout(d time.Duration): Sets the timeout for establishing a TCP connection. Default: 5s.
• WithReadTimeout(d time.Duration): Sets the maximum time to wait for a server response. Default: 5s.
• WithWriteTimeout(d time.Duration): Sets the maximum time to complete sending a request. Default: 5s.
• WithAutoClose(enabled bool): If true, closes the connection after each Execute (default). Use false to reuse the session manually via client.Close().

Requirements

• Go 1.24 or later
• MetaTrader 4 server with TCP access
