Ly,
In the Database Setting window you need to change 'number of bars' field to
how ever many bars of 1-minute data you want to keep. Assuming 24 hour
trading, you will need 1,440 bars per day.

Subject: [amibroker] Accumulating IB backfill data ?
Hi,
using the IB plugin in 1 minute backtest mode I can get 1 month worth
of data, but new data overwrite old data so that I always end up with
ony 1 month backfill.
Is there a way to keep storing data without loosing old one?
I think it can be done by exporting data with fput and then merging
appropriately different files or appending data, but I would like to
know if it can be done in same other AB built-in way.
Thanks
Ly
