Common Questions and Troubleshooting

1. Why do I get "NA" or an empty string?
   • The symbol may be invalid. Double-check the ticker.
   • There might be no pre-market trades yet for that particular security.
   • Ensure you have typed the function and parameter correctly.

2. What if I see "ERR" or a licensing message?
   • Check that your MarketXLS license is valid and active.
   • Make sure your DataSeller subscription is properly configured in MarketXLS settings.

3. Can I use multiple QM_Stream_PreMarketLast calls in the same sheet?
   • Yes, you can add as many function calls as needed. MarketXLS will queue each symbol for real-time updates automatically.

4. Is pre-market data always available?
   • Pre-market data depends on trading activity and availability from the data provider. If there’s no market activity, the function may not return a price.
