Data Limitations

Interactive Brokers places the following limitations on realtime and historical data accessible to 3rd party applications

• Pacing Violations – TWS limits the number of requests for data. It too many requests for data occur in a short period of time, you may see error messages indicating “Pacing Violation”. If this happens you may need to wait a few minutes before trying to load data again.

• Real Time Quotes – TWS does impose limits on the number of active tickers (typically around 100). Additional booster packs can be purchased from IB to work around this issue: Booster Packs.

• Delayed Data Not Supported – TWS does not provide access to delayed historical data and quotes.

For more details on these limitations see IB Data Limitations.
