R

Hi, i'm trying to learn using python to access to IB, but i got stuck before i start.

I copied this script from the documentation of IB for a test:

from ib_insync import *

ib = IB()
ib.connect('127.0.0.1', 7497, clientId=1)

and i have this error:

API connection failed: ConnectionRefusedError(10061, "Connect call failed ('127.0.0.1', 7497)")
Make sure API port on TWS/IBG is open
Traceback (most recent call last):

check in TWS settings if API access authorization is enabled?
also checks if the IP used is the same as the configuration IP in the TWS settings
 
Thanks for the answers,

Have you enabled API access to your TWS or Gateway? The error message hints that this is not the case.

where can i check if the IP is the same as the configuration IP in the tws settings?
 
Do you have a paper trading account or real account @ iB?
From the code you pasted it looks like it's trying to connect to TWS on port 7497

Port 7497 is for connection to TWS using paper trading account
Port 7496 is for connection to TWS using real trading account

Port 4002 is for connection to IB Gateway using paper trading account
Port 4001 is for connection to IB Gateway using real trading account

yeah! now it works with the port 7496 :) thanks otctrade :)
 
You are welcome! If you are starting out and wanting to send trade orders, I would recommend opening a paper trading account (it's free) and trying the API through that.
