The message "Attempting to retrieve data" may appear on the top part of TWS charts when the system is not able to immediately retrieve all of the chart data due to one of the following reasons:
- You are requesting a large amount of historical data or you are querying data on multiple charts simultaneously. In this case the system may take longer to populate the charts. You can try to increase the bar size, reduce the time period or reduce the overall number of open charts in order to respect the pacing limitations defined on our Users' Guide.
- You might experience a connectivity issue towards one or more market data server. Click on the "DATA" icon present on right side of the TWS toolbar. This will bring up a panel with the status of your market data connections. Should you see one or more connections having a red Status (Disconnected), please perform the steps explained in our Knowledge Base.
In any other case, please contact IBKR Client Services for further troubleshooting.
