Here’s a basic example to get you started:

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

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

def historicalData(self, reqId, bar):
print(f'Time: {bar.date} Open: {bar.open} High: {bar.high} Low: {bar.low} Close: {bar.close} Volume: {bar.volume}')

def main():
app = IBApi()
app.connect("127.0.0.1", 7497, 0)

contract = Contract()
contract.symbol = "AAPL"
contract.secType = "STK"
contract.exchange = "SMART"
contract.currency = "USD"

app.reqHistoricalData(1, contract, "", "1 D", "1 min", "TRADES", 1, 1, False, [])

app.run()
