My minute database is set to 500000 bars.
AB warns you on SAVE about setting higher than 100000 bars being slow.
There is also a setting in Preferences->Data

Hi John,
I don't think you can go beyond 30000 bars in the database settings.
I tried and it doesn't work, as I think is also explained in AB
manual.
Backfill is 30000 bars, but what I want is to store new data in real
time, so that over time there are more than 30000 bars.
Right now I can only get the last 30000, so that for each new bar one
is loss from at the beginning of the database (oldest data are loss)
Can you accumulate more than a month of 1 minute data the way you
said?
Thanks
Ly
