Check your database settings and make it longer than
5000 bars.
5000 bars is 15 years or 1990.
If you increase it to say 10,000 bars then a screening
of say
a Russell 2000 component list will be impacted the
first time
you load all of those bars in memory. The second time
around
all the data is loaded in memory and your screening
will be much
faster.
One way to verify how much data you have in memory is
to use
a chart or the Quote Editor that lays out every
bar. Ticker/Date/OHLCV/OI.
Hope this helps.

Thanks Duke,
Ill try it out. One more question. It
seems on the
backtest I did, that I cant get any dates past 1990.
Is
there a way to get it to download before 1990?
