I know that IB backfills is ultra slow and does not work the same way as IQFeed etc, so the setting "Wait for backfill" does not have any effect. And reading the manual, it looks like the only way to backfill every RT-quote is to click "Backfill all RT-quotes".
So I am wondering if there is any way to setup that backfill procedure using the Batch feature? Or is OLE automation the only way? Speed does not matter since I will be backfilling after the markets are closed.
