I am trying to write a trading bot using C++ in vscode which will be connected to metatrader 5 via binding (zeromq) on macOS. But after I installed brew install zeromq and also moved the zmq.h to :

” /Users/kiro/Library/Application Support/net.metaquotes.wine.metatrader5/drive_c/Program Files/MetaTrader 5/MQL5/Include/include “

and file libzmq.dylib to :

“/Users/tuanhungbuivan/Library/Application Support/net.metaquotes.wine.metatrader5/drive_c/Program Files/MetaTrader 5/MQL5/Libraries”

I am unable to bind the server, can someone help me?

For now I only use the example code to try to connect to the server via binding. When I compile this code, there is no error. But when I drag the script in Metatrader 5 to the chart I get those errors:

”’

#import "libzmq.dylib"
int zmq_ctx_new();
int zmq_socket(int context, int type);
int zmq_bind(int socket, string endpoint);
int zmq_recv(int socket, uchar &data[], int len, int flags);
int zmq_send(int socket, uchar &data[], int len, int flags);
int zmq_close(int socket);
int zmq_ctx_term(int context);
#import

void OnStart() {
    int context = zmq_ctx_new();
    int socket = zmq_socket(context, 4); // ZMQ_REP
    zmq_bind(socket, "tcp://*:5555");

    uchar data[];
    ArrayResize(data, 256);

    while (true) {
        zmq_recv(socket, data, 256, 0);
        Print("Received request: ", CharArrayToString(data));

        string reply = "World";
        uchar replyData[];
        StringToCharArray(reply, replyData);
        zmq_send(socket, replyData, StringLen(reply), 0);
    }

    zmq_close(socket);
    zmq_ctx_term(context);
}

When I compile it, there is no error. But when I drag the script on chart I get those errors:

2024.06.22 18:18:35.410 mql5 (EURUSD,M15) cannot load ‘C:Program FilesMetaTrader 5MQL5Librarieslibzmq.dylib’ [193]

2024.06.22 18:18:35.413 mql5 (EURUSD,M15) unresolved import function call

on other hand code in c++ in vscode looks like this

””

#include <zmqpp.hpp>
#include <iostream>
#include <string>

int main() {
    try {
        zmqpp::context context;
        zmqpp::socket socket(context, zmqpp::socket_type::req);
        std::cout << "Connecting to server..." << std::endl;
        socket.connect("tcp://localhost:5555");

        std::string request = "Hello, MT5";
        zmqpp::message message;
        message << request;
        std::cout << "Sending message: " << request << std::endl;
        socket.send(message);

        zmqpp::message reply;
        std::cout << "Waiting for reply..." << std::endl;
        socket.receive(reply);
        std::string reply_str;
        reply >> reply_str;
        std::cout << "Received: " << reply_str << std::endl;
    } catch (const zmqpp::exception& e) {
        std::cerr << "ZeroMQ Exception: " << e.what() << std::endl;
    } catch (const std::exception& e) {
        std::cerr << "Standard Exception: " << e.what() << std::endl;
    } catch (...) {
        std::cerr << "Unknown Exception" << std::endl;
    }

    return 0;
}

and after building the code control + shift +b and ./main in the terminal I get this:

Connecting to server…

Sending message: Hello, MT5

Waiting for reply…
