reqFundamentalData IBKR

Question

It seems that the TWS API request reqFundamentalData is no longer working. I'm using TWS version 10.19.2. It appears that the server is functioning, but the response is empty; I'm not getting any feedback.

# Initializing
class IBapi(EWrapper, EClient):
    def __init__(self):
        EClient.__init__(self, self)

    # Error handling function
    def error(self, reqId, errorCode, errorString):
        print("error: ", reqId, " ", errorCode, " ", errorString)
        if errorCode == 504:  # Not connected error
            print("Attempting to reconnect...")
            self.reconnect()

    # Inherit and overwrite fundamentalData() function in EWrapper
    def fundamentalData(self, reqId: int, data: str):
        super().fundamentalData(reqId, data)
        self.fundamental_data = data  # Store fundamental data in instance variable
        print("FundamentalData Returned. ReqId: {}, Symbol: {},  XML Data: {}".format(
        reqId, self.contract.symbol, data))
        self.display_fundamental_data()  # Call function to display fundamental data

    def display_fundamental_data(self):
        if hasattr(self, 'fundamental_data'):
             print("Fundamental Data:", self.fundamental_data)
        else:
            print("No fundamental data available.")

    def reconnect(self):
        self.disconnect()
        t.sleep(5)  # Wait for 5 seconds before reconnecting (renamed to t)
        self.connect("127.0.0.1", port=7497, clientId=990)

tws = IBapi()                       
tws.connect("127.0.0.1", port=7497, clientId=990)
t.sleep(5)  # Renamed to t
print("Connected to IB server.")

c = Contract()
c.symbol = 'AAPL'  # Changed to c.symbol
c.secType = 'STK'  # Changed to c.secType
c.exchange = "SMART"  # Changed to c.exchange
c.currency = "USD"  # Changed to c.currency

tws.reqFundamentalData(1, c, 'ReportsFinStatements', [])
print("Requested fundamental data for symbol AAPL.")
t.sleep(10)  # Renamed to t
# Implement other requests

tws.disconnect()
print("Disconnected from IB server.")

Here is the result.

Connected to IB server.
Requested fundamental data for symbol AAPL.
Disconnected from IB server.

I thought the code looked ok but it didn't run. I reorganized it a bit and realized you just forgot to call run().

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
import time as t

class IBapi(EWrapper, EClient):
    def __init__(self):
        EClient.__init__(self, self)

    def error(self, reqId, errorCode, errorString, reject):
        print("error: ", reqId, " ", errorCode, " ", errorString)

    def nextValidId(self, orderId:int):
        c = Contract()
        c.symbol = 'AAPL'  # Changed to c.symbol
        c.secType = 'STK'  # Changed to c.secType
        c.exchange = "SMART"  # Changed to c.exchange
        c.currency = "USD"  # Changed to c.currency
        self.contract = c
        self.reqFundamentalData(1, c, 'ReportsFinStatements', [])
        print("Requested fundamental data for symbol AAPL.")
        
    # Inherit and overwrite fundamentalData() function in EWrapper
    def fundamentalData(self, reqId: int, data: str):
        super().fundamentalData(reqId, data)
        self.fundamental_data = data  # Store fundamental data in instance variable
        print("FundamentalData Returned. ReqId: {}, Symbol: {},  XML Data: {}".format(
        reqId, self.contract.symbol, data))
        self.display_fundamental_data()  # Call function to display fundamental data
        self.disconnect()
        print("Disconnected from IB server.")
        
    def display_fundamental_data(self):
        if hasattr(self, 'fundamental_data'):
             print("Fundamental Data:", self.fundamental_data)
        else:
            print("No fundamental data available.")

tws = IBapi()                       
tws.connect("127.0.0.1", port=7497, clientId=990)
tws.run() # pretty sure you just forgot this line
