Steve,
no one can screen or even purchase all
stocks contained in your database. Therefore, simply try the following
pre-filter to weed out unwanted stocks:
<FONT face="Courier New" color=#009300
size=1>
// Scan your database with this small sample code daily or devise minor or
even larger modifications to this code!<FONT face="Courier New"
size=1>
// Here is your price preference for a pre-filter to remove unwanted stocks.
The pre-filter might be varied if you like, but it could be like this
one.
// Note that the stock prices occur in between a $10-$50 price
range having also a decently high - but not an exceedingly large -
volume:
preFilter = (<FONT face="Courier New" color=#ff00ff
size=1>1 < <FONT

Betreff: [amibroker] All Those
Tickers........
As I speak, I'm downloading the 'Complete US Stocks
Database', some 7700 symbols in all, nicely arranged in
Market/Groups/Sectors.Thing is, I don't really want all 7700 symbols. I
get confused enough with a few hundred. So, the question is can I scan
this vast database and select/keep only those with (for
example):C*MA(V,21)>3,000,000I know how to do the
scan/exploration, how do I eliminate the unwanted tickers, but keep the
wanted tickers in their correct Groups/Sectors? <FONT
color=#ff0000>// Based on the performance of the
stocks??Thanks,SteveSend
