How can I get a connection from Python to Metatrader 4 using ZeroMQ – Telegram API

I want an Expert Advisor to open an Trade triggerd by a Telegram-Message.

I succesfully set up an Hello-World application using MQ4 as Server and Python/Telegram-bot as Client.
When the Telegram-Bot recieves a Message, he will send a request to MQ4 and gets a simple response without executing a trade.

Running Code below.

#   Hello World client in Python
#   Connects REQ socket to tcp://localhost:5555

import zmq
context = zmq.Context()

#  Socket to talk to server
print("Connecting to trading server…")
socket = context.socket(zmq.REQ)
socket.connect("tcp://localhost:5555")
print("Connecting to trading server succeed")

# Use your own values from my.telegram.org

#################################################################################

from telethon import TelegramClient, events

client = TelegramClient('anon', api_id, api_hash)

@client.on(events.NewMessage)
async def my_event_handler(event):


    if "Ascending" in event.raw_text:

        if "AUDUSD" in event.raw_text:
            await event.reply("AUDUSD sell")

            #  Do 1 request, waiting for a response
            for request in range(1):
                print("Telegram: AUDUSD sell execution requested %s …" % request)
                socket.send(b"AUDUSD Sell execute")
                #Send 2 variables (Ordertype // Symbol)

                #  Get the reply. -> Not neccesary for final application
                #  Apülication just needs to send 2 Varianles to MQ4 and trigger the open_order()
                message = socket.recv()
                print("Received reply %s [ %s ]" % (request, message))



client.start()
client.run_until_disconnected()

// Hello World server in MQ4

#include <Zmq/Zmq.mqh>

//+------------------------------------------------------------------+
 void OnTick()
  {
   Context context("helloworld");
   Socket socket(context,ZMQ_REP);

   socket.bind("tcp://*:5555");

   while(!IsStopped())
     {
      ZmqMsg request;

      // Wait for next request from client

      // MetaTrader note: this will block the script thread
      // and if you try to terminate this script, MetaTrader
      // will hang (and crash if you force closing it)

      socket.recv(request);
      Print("Receive: AUDUSD Sell execute");

      Sleep(1000);

      ZmqMsg reply("Trade was executed");
      // Send reply back to client
      socket.send(reply);
      Print("Feedback: Trade was executed");
     }
  }
//+------------------------------------------------------------------+

Now I want to send 2 variables from Python to MQ4.
1. Ordertype: buy/sell
2. Symbol: EURUSD, AUDUSD,…

Send “Sell” if message contains “Ascending” –
Send “Buy” if message contains “Descending”

Send “AUDUSD” if message contains “AUDUSD”,…

To do so I found a Library from Darwinex and want to combine it (interpretation of message, sending value as an array) with my already functioning telegram-bot.

For testing I wanted to try the example-code from Darwinex by itself.

I found the Code v2.0.1:

Python:
https://github.com/darwinex/DarwinexLabs/blob/master/tools/dwx_zeromq_connector/v2.0.1/Python/DWX_ZeroMQ_Connector_v2_0_1_RC8.py

MQ4: (Note: This Library code may replace the whole MQ4 code above in final app.)
https://github.com/darwinex/DarwinexLabs/blob/master/tools/dwx_zeromq_connector/v2.0.1/MQL4/DWX_ZeroMQ_Server_v2.0.1_RC8.mq4

When I copy the Code without changing I get an error in Python:

NameError: name ‘_zmq’ is not defined

After running: _zmq._DWX_ZeroMQ_Connector() – in the Kernel of Spyder.

What can I do to fix that error?

In the final state I want to run the Python-Code and the Expert Advisor on the same Windows Server 2012 R2.

Is it enough if I run the .py file in the powershell from the server or should I host the file with the Webside?

I expect to get the whole system/examplecode running on my VPS or Webside-Host-Server and get an testing environment for further coding action, but currenty I cant get the Library Code in Python to run properly.

Also the MT4 ceeps crashing with the current code – but should be fixed if I combine my application with the Library-Codeexample.

(running everything on my local PC with WIN 10).
