Basic Examples for MT4 (for MT5 click here)

Example 1: Get actual EURUSD price from MT4 using Go

package main

import (
    "fmt"
    "net"
)

func main() {
    con, err := net.Dial("tcp", "localhost:77")
    if err != nil { fmt.Println(err) }
    defer con.Close()
    msg := "{\"MSG\":\"QUOTE\",\"SYMBOL\":\"EURUSD\"}\r\n"
    _, err = con.Write([]byte(msg))
    if err != nil { fmt.Println(err) }
    reply := make([]byte, 1024)
    _, err = con.Read(reply)
    if err != nil { fmt.Println(err) }
    fmt.Println(string(reply))
}

Result:

{
   "MSG":"QUOTE",
   "SYMBOL":"EURUSD",
   "ASK":1.08293,
   "BID":1.08291,
   "FLAGS":6,
   "TIME":"2022.04.13 08:33:48.0",
   "VOLUME":0,
   "ERROR_ID":0,
   "ERROR_DESCRIPTION":"no error"
}

Example 2: Send Order to MT4 using Go

package main

import (
    "fmt"
    "net"
)

func main() {
    con, err := net.Dial("tcp", "localhost:77")
    if err != nil { fmt.Println(err) }
    defer con.Close()
    msg := "{\"MSG\":\"ORDER_SEND\",\"SYMBOL\":\"EURUSD\",\"TYPE\":\"ORDER_TYPE_BUY\",\"VOLUME\":0.02}\r\n"
    _, err = con.Write([]byte(msg))
    if err != nil { fmt.Println(err) }
    reply := make([]byte, 1024)
    _, err = con.Read(reply)
    if err != nil { fmt.Println(err) }
    fmt.Println(string(reply))
}

Result:

{
   "MSG":"ORDER_SEND",
   "TICKET":47103114,
   "ERROR_ID":0,
   "ERROR_DESCRIPTION":"no error"
}

Example 3: Stream actual EURUSD price from MT4 using Go

package main

import (
    "fmt"
    "net"
)

func main() {
    con1, err := net.Dial("tcp", "localhost:77")
    if err != nil { fmt.Println(err) }
    con2, err := net.Dial("tcp", "localhost:78")
    if err != nil { fmt.Println(err) }
    defer con1.Close()
    defer con2.Close()
    msg := "{\"MSG\":\"TRACK_PRICES\",\"SYMBOLS\":[\"EURUSD\"]}\r\n"
    _, err = con1.Write([]byte(msg))
    if err != nil { fmt.Println(err) }
    reply := make([]byte, 1024)
    _, err = con1.Read(reply)
    if err != nil { fmt.Println(err) }
    fmt.Println(string(reply))
    for{
        _, err = con2.Read(reply)
        if err != nil { fmt.Println(err) }
        fmt.Println(string(reply))
    }
}

Result:

{"MSG":"TRACK_PRICES","SUCCESS":["EURUSD"],"ERROR_ID":0,"ERROR_DESCRIPTION":"no error"}

{"TIME":"2022.04.13 09:08:02","SYMBOL":"EURUSD","ASK":1.08386,"BID":1.08384,"VOLUME":18404}

Advanced Examples

Example 1: Get actual EURUSD price from MT4 (using JSON library) using Go

package main

import (
    "encoding/json"
    "fmt"
    "net"
)

type quoteCommand struct {
    MSG    string
    SYMBOL      string
}

func main() {
    cmd := quoteCommand{
        MSG: "QUOTE",
        SYMBOL:   "EURUSD",
    }
    jsonData, err := json.Marshal(cmd)

    con, err := net.Dial("tcp", "localhost:77")
    if err != nil { fmt.Println(err) }

    msg := string(jsonData) + "\r\n"
    _, err = con.Write([]byte(msg))
    if err != nil { fmt.Println(err) }
    
    reply := make([]byte, 1024)
    msgLen, err := con.Read(reply)
    if err != nil { fmt.Println(err) }
    
    con.Close()

    bytes := []byte(string(reply[0:msgLen]))
    var result map[string]interface{}
    json.Unmarshal(bytes, &result)

    fmt.Printf("Symbol: %s  Ask: %f   Bid: %f\n", result["SYMBOL"],result["ASK"],result["BID"])
}

Result:

Symbol: EURUSD  Ask: 1.022240   Bid: 1.022200
