Hi Jim,
I see that Graham has given you the answer (ah, the
advantages of living a day in the future <VBG>).
It is this additional step that led me to comment that
I didn't find the Database Purify tool as easy to use when just deleting
dead tickers. It is a wee bit safer as you can review each stock, but time
consuming. The original Cleanup Database script also lets
you review each entry before deletion (actually forces you to affirm a
deletion), and if you only have a few tickers, that's fine. However Quotes
Plus has a garbage bin of inactive tickers -- they do not show in the QP
program, however every time I refresh my QP database I get > 500 dead tickers
and deleting each one individually is way too tedious. Hence my tweak to
create the EZ Cleanup script. Besides nothing is truly deleted, just
removed from the AB database. It's all there in your master DB
(if you use TC2005 or QP). Or you could make a backup
copy of our AB database before running either of the cleanup tools if
you are a belt and suspenders type.
Hope this make sense.
Peace and Justice ---

Subject: [amibroker] NW TRADER VS
DATABASE PURIFY TOOL
In a note named 'STOCK TICKERS GO TO THE
P's, THEN
STOP??' you alerted me to two courses of action. I
am
trying the first method, the Database Purify Tool. I
invoked
this little window and hit the Analyze button
at the bottom. Now I
have a list of tickers that I
want to remove, including blank tickers with
no names,
but it is not clear how to actually remove them.
The
on-line manual merely states that this 'tool allows to
detect
missing/extra quotes, possible splits or
invalid OHLC relationship' but
doesn't specify how to
actually remove the moridbund stickers.
Any
suggestions on how to 'delete' this list?
Thanks
for your patience and help. I have not yet
moved on to your second
suggestion.
Jim Brady
