If you’re not connected, select your data provider to establish the connection. * If you’re already connected, try **disconnecting** and reconnecting by selecting **"Disconnect"**, waiting a few seconds, and then selecting **"Connect"** again to refresh the data feed. * Check your internet connection to ensure it’s stable and functioning properly. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/a/0/d/da0d2c9572aef000/image_fhtcna.png) 2. **Restart NinjaTrader** If market data is still not appearing or is incorrect, restart NinjaTrader to refresh the platform and connection: * Close NinjaTrader completely. * Reopen the application, and it will attempt to reconnect to your data provider and reload the necessary market data. 3. **Check Instrument Settings** If data for a specific instrument is missing or incorrect, verify that the instrument settings are correctly configured: * Open the **Instrument Manager** in NinjaTrader. * Search for the instrument you are having issues with. * Confirm that the correct symbol and data provider are selected. * If necessary, adjust the settings or reselect the appropriate provider. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/a/0/d/da0d2c9572aef000/image_18m0g5w.png) ![](https://storage.crisp.chat/users/helpdesk/website/-/d/a/0/d/da0d2c9572aef000/image_l5wags.png) 4. **Level 2 Data Subscription** If you are connected to a **Rithmic** data connection, and you are seeing only the last traded price with no market depth (i.e., no Level 2 data), it means your account does not have Level 2 data enabled. The following steps can resolve this: * You will need to contact your broker or data provider to subscribe to **Level 2 data** for the instruments you’re trying to load in NinjaTrader. After subscribing to Level 2 data, restart NinjaTrader to begin receiving live market depth data. 5. **Reset Your Market Data Feed** If you’re still facing issues, resetting the data feed can force NinjaTrader to request fresh data: * In the **"Connections"** menu, click **"Disconnect"** from your active data connection. * Wait a few moments and then click **"Connect"** again to re-establish the connection. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/a/0/d/da0d2c9572aef000/image_aqn6qm.png) 6. m**Check for Data Subscription Issues** If you’re using a third-party data provider, ensure your subscription is active and up to date: * Log into your data provider’s account and verify your subscription status. * Ensure there are no service interruptions or technical issues with your data provider. Check their status page for updates. 7. **Update NinjaTrader to the Latest Version** It’s crucial to keep NinjaTrader up to date to avoid bugs or data issues: * Go to **Help > About** from the NinjaTrader menu to check the version you have. * Go to **Help > Download** to view the latest version available and download if there’s a newer version available. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/a/0/d/da0d2c9572aef000/image_whxqnl.png) 8. **Reload Historical Data** If you’re experiencing issues with missing historical data or gaps in your charts, you can reload the data from your data provider: * Right-click on your chart and select **"Reload Historical Data"** or press **Ctrl+Shift+R** on your keyboard. * Ensure you are connected to your data provider when performing this action. You may notice a **"Loading"** symbol as the data is downloaded from your provider’s servers. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/a/0/d/da0d2c9572aef000/image_uzrzot.png) 9. **Clear Historical Data Cache ** If you notice long chart loading times or persistent data issues, clearing the Historical Data Cache can improve performance: * Close NinjaTrader. * Open **Windows File Explorer** (Press **Windows Key + E**). * Navigate to the **Documents/NinjaTrader 8/db** folder. * Delete the **‘tick’**, **‘minute’**, **‘day’**, and **‘cache’** folders (do **not** delete any other folders). * Restart NinjaTrader, and your platform will automatically re-download the necessary data, though there may be a longer initial loading time. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/a/0/d/da0d2c9572aef000/image_xdolur.png) 10. **Check for System-Wide Data Feed Outages** On rare occasions, data providers may experience system-wide outages that impact data feeds: * Visit NinjaTrader’s website or the website of your data provider. * Check for any outages or maintenance activities that may be affecting the data feeds. 11. **Contact Support** If none of the steps above resolve the issue, contact NinjaTrader support or your data provider for further assistance: * Submit a support request to NinjaTrader or your data provider’s support team. * Provide detailed information about the issue, including the data provider, instrument, and any troubleshooting steps you’ve already taken.
