I'm trying to display continuous volume bars with data pulled from a live IB account.
1) The chart populates fine as long as I'm connected to with TWS, but I can't get the chart to back fill with older data. How do I get NT to request historic tick data from IB, or is that not possible?
2) I think I have the chart data series set up correctly for 16807 vol, but would appreciate it if someone can confirm for me. I'm looking to build charts per William (Bill) Schamp's CVB definitions.
Thanks in Advance!
