Why data issues happen
Many IBKR data failures are configuration issues rather than code bugs.
Permissions, exchange coverage, and contract precision all affect response quality.
Troubleshooting checklist
- Confirm market-data subscriptions for the instrument and venue.
- Verify contract fields exactly match the intended instrument.
- Check whether requests hit pacing constraints.
- Use explicit logging for request parameters and broker responses.
Operational guidance
- Document entitlement assumptions in your environment setup docs.
- Test critical symbols in paper and production-like contexts.
- Keep fallback diagnostics in place for sudden data changes.
