[amibroker] Dynamically Defining number of Bars to be Loaded

["dweilmuenster95125" <dweilmuenster95125@xxxxxxxxx>]

Once a database is defined for AmiBroker, is it possible in
Explorations or Backtests to specify that the program should load only
a specific number of the most recent bars in the database, rather than
the maximum number defined when creating the database.

For example, if a database is defined to load 3000 bars of daily data
from TC2005, is there a way in an Exploration or Backtest to specifiy
that only the most recent 500 bars should be loaded for that
Exploration or Backtest?

Why?  Some of my backtesting requires 10 years of data.  Explorations
typically require only 2 years.  But, AmiBroker loads all 10 years for
explorations whether I need it or not because the database is defined
to accommodate the maximum number of bars for backtesting and
exploring.  That stretches the time to complete Exploration
susbstantially.

Thanks,
David
