yesterday my code was working fine, but today without any reason for me (and no changes to the code) I can not connect to Interactive Brokers TWS via ib_insync
The code itself is longer but error appears after I try to connect to IB
Code is:
from ib_insync import IB
ib = IB()
ib.connect('127.0.0.1', 7497, clientId=1, readonly=True)
Error messege is:
Traceback (most recent call last): File "C:\Users\Yar\AppData\Local\Programs\Python\Python310\lib\asyncio\tasks.py", line 458, in wait_for fut.result() asyncio.exceptions.CancelledError
The above exception was the direct cause of the following exception:
Traceback (most recent call last): File "C:\Users\Yar\PycharmProjects\positionkeeping2\err.py", line 4, in ib.connect('127.0.0.1', 7497, clientId=1, readonly=True) File "C:\Users\Yar\PycharmProjects\positionkeeping2\venv\lib\site-packages\ib_insync\ib.py", line 279, in connect return self._run(self.connectAsync( File "C:\Users\Yar\PycharmProjects\positionkeeping2\venv\lib\site-packages\ib_insync\ib.py", line 318, in _run return util.run(*awaitables, timeout=self.RequestTimeout) File "C:\Users\Yar\PycharmProjects\positionkeeping2\venv\lib\site-packages\ib_insync\util.py", line 341, in run result = loop.run_until_complete(task) File "C:\Users\Yar\AppData\Local\Programs\Python\Python310\lib\asyncio\base_events.py", line 641, in run_until_complete return future.result() File "C:\Users\Yar\PycharmProjects\positionkeeping2\venv\lib\site-packages\ib_insync\ib.py", line 1782, in connectAsync await asyncio.wait_for(self.reqExecutionsAsync(), timeout) File "C:\Users\Yar\AppData\Local\Programs\Python\Python310\lib\asyncio\tasks.py", line 460, in wait_for raise exceptions.TimeoutError() from exc asyncio.exceptions.TimeoutError
I have tried to reisntall TWS API, reboot the computer etc - nothing has helped. I have checked all the API settings - they are correct (7497 - port, ActiveX and Socket Clients Enebled)
Also the following code (which uses ibapi) is workig fine and connects to TWS. So I can connect to TWS via ibapi bit not via ib_insync
from ibapi.client import *
from ibapi.wrapper import *
class TestApp(EClient, EWrapper):
def __init__(self):
EClient.__init__(self, self)
self.instrument = None
self.bid_price = None
self.ask_price = None
def nextValidId(self, orderId: int):
self.reqMarketDataType(1)
self.reqMktData(orderId, self.instrument, "", True, 0, [])
def tickPrice(self, reqId, tickType, price, attrib):
if tickType == 1: # Bid Price
self.bid_price = price
elif tickType == 2: # Ask Price
self.ask_price = price
if self.bid_price is not None and self.ask_price is not None:
print(f"{self.bid_price} / {self.ask_price}")
print(f'ReqId: {reqId}')
self.cancelMktData(reqId)
self.disconnect()
def mainProc ():
instrument_data = {"symbol": "NG", "secType": "FUT", "exchange": "NYMEX", "currency": "USD", "lastTradeDateOrContractMonth": 202306}
app = TestApp()
app.connect("127.0.0.1", 7497, 1)
contract = Contract()
contract.symbol = instrument_data["symbol"]
contract.secType = instrument_data["secType"]
contract.exchange = instrument_data["exchange"]
contract.currency = instrument_data["currency"]
contract.lastTradeDateOrContractMonth = instrument_data["lastTradeDateOrContractMonth"]
app.instrument = contract
app.run()
app.disconnect()
mainProc()
