"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

If I have iQConnect running, then my app works.

However when I try and start iQConnect in my app, I can't connect and it says:

ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

The log appears below. What am I missing?

Python code
===

import subprocess
import socket

pr = open("product.txt", "r")
product = pr.read()
l = open("login.txt", "r")
login = l.read()
p = open("password.txt", "r")
password = p.read()

subprocess.run(["IQConnect.exe","-product",product,"-version","0.5","-login",login,"-password",password,"-autoconnect"])

host = '127.0.0.1'
port = 9300

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))

I figured it out. I created and ran a separate app that opens iQConnect and logs in, then I run my app and everything works fine.

Error 10061 is a socket error meaning "connection refused". IQFeed doesn't refuse connections, except for reasons it will explain in the log, like bad credentials. And this is one of those times.

The 30-second log you see in the countdown is the IQFeed server waiting for you to make a socket connection. If you have a connection to the server, you have 30 seconds to make a socket connection, or the server disconnects you. Opening an IQFeed app first, as you're doing now, creates at least one socket connection, which prevents this countdown from happening. But it's not the only possible resolution.

What I don't understand is that if I run the iQConnect app from my (slightly improved) code and then start a separate app with the socket connection, then it works.

But when I try and use this line

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

in the connect.py application (see below) then the connection is refused. Why does the line work in a separate application but not in the connect.py app?

Can you give me a hint as to another possible resolution?

Thanks!



=== connect.py file ===

import time
import win32api

def readline(textfile):
filename = textfile + '.txt'
temp = open (filename,'r')
content = temp.read()
return content

product = readline('product')
login = readline('login')
password = readline('password')

iqfeed_args = ("-product %s -version 0.5 -login %s -password %s -autoconnect" %
(product, login, password))

win32api.ShellExecute(0,'open', 'IQConnect.exe', iqfeed_args,'',1)

# give myself 10 seconds to start the other app
time.sleep(10)

I found a way to cover most of the edge cases. Recall that one may connect to several different ports on the local IQFeed exe server. One of those is the admin port. So firts, I try to connect to the admin port just as a test to see if IQFeed is already running. If that fails twice (after pausing between attempts), I call a shell script (a batch file on Windows) which runs IQFeed.exe. Then I try to connect 3 more times (after pauses). Since my rust code might looke like gobbledygook, I'll demonstrat this with pseudo code that resembles python (but is not actually python):

admin_conn_attempts = 0
conn_attempt_pause_seconds = 4
while True:
    admin_conn = tcp_connect("127.0.0.1", 9300) #the admin socket
    if admin_conn.is_connected():
        break
    else
        sleep(conn_attempt_pause_seconds)
        admin_conn_attempts += 1
        if admin_conn_attempts == 2:
            # run external program to start IQFeed.exe
            run.program(IQFeed.exe)
        else if admin_conn_attempts > 5:
            print("ERROR: Unable to connect to IQFeed")
            exit -1


If i get this far in the code and it didn't exit, that means I'm connected.

I'm aware IQFeed should just start automatically if it's not running but I'm running under Wine on Linux and I have not observed that behavior. I call a shell script to run it (instead of the executable itself) because I set some additional environment things up before running -- such as pinning IQFeed to a certain set of cores on my multi-core processor.
