If you are using mixed EOD/intraday mode then both (EOD and 1-minute) are retrieved at the same time.
Tick-by-tick (i.e. single trade by trade) data is other story. These are *huge* data sets.
Single day can be as much as 10 MB of data and more than 200000 ticks per day is not rare.
They don't mix with EOD.
You may be quickly running out of storage space and/or 'number of bars' limit as
set in the database settings.

Thank you Tomasz. When you use the exploration backtest with the wait
for backfill on, is the historical data that is gathered Daily or
Intraday? I use tick volume to display volume charts and it is the
historical tick data that I wish to save. Thank you.
