IBKR Historical Bars to pandas Workflow
A clean pipeline for requesting IBKR historical bars and converting them into a pandas DataFrame for analysis.
Workflow objective
Turn IBKR historical bars into a reproducible pandas structure with explicit timestamp handling.
This is a core building block for strategy analysis and reporting.
Python example
from ib_insync import IB, Stock, util
import pandas as pd
ib = IB()
ib.connect("127.0.0.1", 7497, clientId=23)
contract = Stock("AAPL", "SMART", "USD")
bars = ib.reqHistoricalData(
contract,
endDateTime="",
durationStr="3 M",
barSizeSetting="1 day",
whatToShow="TRADES",
useRTH=True,
)
df = util.df(bars)[["date", "open", "high", "low", "close", "volume"]]
df["date"] = pd.to_datetime(df["date"])
print(df.tail(3))
