@DdlV I see. I misunderstood your question. Do you want to create a .csv file containing the history values of all the symbols in *symbols? I'm afraid Zorro doesn't provide this functionality. But you can use the ZHistoryEditor (http://server.conitec.net/down/ZHistoryEditor.zip) to create .csv file for each symbol from the .t6 file then combine them to a single .csv. Hopefully, this helps.
