I was surprised to see how fast configure/retrieve retreived ENY
today; it completed considerably sooner than the usual startup 'filling
tree' delay.
Re the renaming problem, Technifilter Plus found ENY in QP, so looks
like it uses different calls.
That Technifilter Plus couldn't find ZZZZ A and related junk [see
tfp.gif vs. ab.gif], seems to reinforce this calling difference.
As I recall, Clay's reply to my complaint that TFP accessed QP data
somwhat slower than QP-generated MStk data was that QP required two
calls: the 1st one determined that data existed.
The comma-separated list format is essential to QP usage. In fact, I
usually add a header so the list can be sorted in the QP SS. For
example,
----
Header:Symbol,Rsi14,OverMA50,OverMA150,macdH,macdDel,Desc,Date
!ID001,30.23,-8.23,-14.38,-1.37,-0.10,Aerospace-Defens
AEROCRFT,02/14/2003
!ID002,32.91,-7.41,-13.39,-0.93,-0.06,Aerospace-Defens
AEROEQUP,02/14/2003
----
Is it that hard to parse off the trailing data? [Clay implemented this
for Technifilter Plus in 1999, when he 1st added QP native access.]
Sorry for the delay -- my cable ISP went down -- regards,
Bob

This is the way how data plugins work right now. Checking for added
symbols on startup for example is too expensive (in terms of
performance)
because QP2 does not provide any means to access "new or renamed"
symbols.
To access them you need to scan through entire database and compare
with what you already have (even this is not perfect in case of renamed
symbols).
Implementing such a feature will increase loading time considerably.

Yes, currently watch lists importer expects just the ticker list
(symbols only)
without quotes.
Such like "SRB Only.LST" file installed by default by Quotes Plus
program in Lists\QP_Lists folder.
To import other formats you have to use ASCII importer.
