Thank you very much. No problem. I will check at the end of January if it works by myself ;-)

Hi, do you think it is possible to have datafeed myself (not sierra chart datafeed) but activate exchange fee on sierra chart site to make this datafeed real-time? Or I need to have sierra chart datafeed first to activate exchange fee (real time)? Best Regards, manfretto

My understanding...

For Sierrachart data you pay exchange fee to Sierrachart.
For other data, you pay whoever your data provider is. If data is through your broker, then pay the broker and they will pay the data provider.
