Thanks for your response. Unfortunately, I don't think the recommended solution will work based on what I read from the link that you shared: Note: When sharing the data between copies of Sierra Chart, the chart data from the Source copy fully comes from the Source copy and is not updated by the Destination copy. So you cannot use historical chart data only from one copy of Sierra Chart and then have that chart updated in real time with the real-time data from the Destination copy. However, the market depth data, and current bid and ask data, can come from the Destination copy. The chart data itself though will always come from the Source copy. I'm trying to use SC to populate historic data and then have the chart update with the IB real time feed. Based on the above, I don't think it is possible but can you please confirm? I also tried the second solution of renaming the file but this seems to have operational constraints. From my trial and error, the only way I could get it to work was to rename the file using the IB symbol but that prohibits me from having two different data files. I would like to have two files: (1) pure IB data for both historic and current day's trading and (2) SC for historic and only the current trading day with IB data. I tried using a different file name and changing the symbol in the Chart Settings to the IB symbol but got the error message of unknown symbol. This leads me to believe that SC software and IB feed communicate based on the actual file name and therefore the symbol listed in chart settings must exactly match the data file name. Can you please confirm? If both files are required to have the same name, can I simply create a Data 2 folder in the Sierra Charts directory? I would then select the appropriate file as necessary because both would be using the IB feed to build the current day's chart but the history would be different for each file (one from IB and the other from SC)? In terms of SC feeds, I see four different options from the drop down (1) SC Historical Intraday Futures Data (2) SC Historical Data (3) SC Market Stats and (4) SC Forex Data (FXCM). Can you please confirm that the only SC real time feed is for forex? All the other SC feeds, such as intraday futures historic, do NOT update real time? I look forward to your response because I should help me gain a better understanding of how the data feeds interact with SC platform. Appreciate your help. |
