I don't have time to look back now to yesterday's posts but here's some more info from NT Support Forum on BRN historical data in regard to the Zen-Fire feed.
"With Zen-Fire the historical data is provided from the NinjaTrader servers for commonly traded products, and so that may not include any historical data for contracts like the CT and BRN, but the real-time data is available.
If you go to Tools > Options > Data you can enable the Save Chart Data as Historical and that will save the real-time data to be available for back-filling purposes on subsequent days.
Otherwise, for more extensive historical data you can supplement the historical data through the Zen-Fire connection with another provider, such as Kinetick, and for more information please see the following link."
