Hi Herman, many thanks for your reply. As I want to work with 1min or 3min data... and I see that you have a lot of knowlege about this problem, is there a workaround, if I want to check the last bars? Ref(-1) to Ref (-3)? So that the bar behind (last bar) it already a backfill data from IB? Would this work with reconnecting to the IB source data and backfilling every 30 sec or every 1min, backfilling the last 1-10 bars?
Greetings, dubi
