I don't know why there is a performance penalty with AmiBroker. I know that
I can access this data in milliseconds through Excel VBA (and VB - I bought
6.0). I can send you this code (Excel Spreadsheet) if you like.
I am trying to see the performance problem you are talking about but I
cannot get the script you posted to work, I keep getting errors (see
attached & I sent you a bug report). The errors are in the following lines:
column0 = Float;
column1 = EPS;
column2 = ROE;
column3 = Dividend;
Like I said in a prior email, I work primarily with the DLL, but that is not
accessible in scripting languages. I am very familiar with the COM add-in
though (I did testing between the two). One item that might cause the
problem is the COM add-in loads 'all data available' for each symbol. This
is one of the reasons I stuck with the DLL - you can specify the amount of
data to load (number of days to load).
Gary Lyben (Quotes Plus Owner) said that he is going to add the ability to
limit the amount of data loaded in the next update to the COM add-in ... but
there was no date specified.
You can drop Gary an email if you wish (gary@xxxx), although he
has not answered any of my private emails lately (not very typical of their
tech support). I will help as much as I can.

Peter,
I guess you talked a lot with QP2 people, do they have any hint
about improving the speed of accessing fundamental data?
The problem might be with that, that I create the instance
of the QP2 object for every stock in the script, but it really
should not have THIS performance penalty.
Best regards,
