IBKR Error Handling and Reconnect Patterns
A practical pattern for handling disconnects, retries, and transient failures in IBKR Python integrations.
IBKRError handlingReconnectReliabilityPython
Reliability principles
- Treat connectivity as unstable and design explicit recovery logic.
- Use bounded retries with logging and alerting.
- Separate retryable transport failures from business-rule rejections.
Python reconnect pattern
python
import time
from ib_insync import IB
def connect_with_retry(host="127.0.0.1", port=7497, client_id=25, attempts=5):
ib = IB()
for attempt in range(1, attempts + 1):
try:
ib.connect(host, port, clientId=client_id, timeout=5)
return ib
except Exception as exc:
print(f"attempt {attempt} failed: {exc}")
time.sleep(min(attempt, 5))
raise RuntimeError("Unable to connect to IBKR after retries")
ib = connect_with_retry()
print("connected:", ib.isConnected())
