D,
Interesting
idea… I hadn’t thought of that.
It ties in nicely
with another idea I’ve been working with – downloading and saving data from
websites using a tool called “Internet Macros”. “Internet Macros”
is a tool specially designed pull (or push) data from (or to) a website.
Reuters, MSN, SmartMoney, and IBD have some excellent information about
fundamentals, insider trading, % held by institutions, etc.
With this tool, you can hit the web pages, download the info and save it to a
database or a text file.
The problem has been
accessing the information quickly and seamlessly. Loading it to an array
in a DLL and then calling the DLL could work out nicely. I’d want
to download the information before doing a scan. But if I wanted
to check the latest information for a chart, the DLL could call an “Internet
Macro”, download the data, save it, and then load it to an array for use by
AB.
Thanks and
regards,
Dan.

best way: write
a dll you call from AB that will access the data in whatever way you want to
store it.

Best Ways of Accessing and
Using External Data
Hi,
I’m trying to load, access and
use NON-price external data in AB scans and indicators. Example: I’m
trying to map Telechart Industry Symbols to Sector Symbols, and use these in
AB. What are the best ways of handling
this?
In general, I’m interested in
two types of external data:
1)
Non-price, single value
(current) data – Current values for symbol-related data.
Examples: Current p/e ratio, current shares outstanding,
next earnings date, and Sector to industry symbol
mapping.
2)
Non-price, historical data –
Similar to number two, except historical. Example: P/e ratio by day
week or month, historical shares outstanding.
Here’s a problem I’m trying to
solve…
I use Telechart
data. They provide Stock to Industry to Sector mapping. And,
they provide Industry and Sector symbol data that can be plotted. And,
Stock symbol to Industry symbol mapping is simple in AB.
But…
There appears to be no simple
way of mapping an Industry symbol to a Sector symbol in AB.
I was thinking of using a simple
CSV file (using “fgets”) containing one line for each TC Industry Symbol
with its associated Sector symbol. For example, the
Telechart Specialty Retail symbol is “MG740”. Its Industry
symbols are “MG741” to “MG747”. So the Specialty Retail section
of the mapping file would contain:
MG741,MG740
MG742,MG740
MG743,MG740
MG744,MG740
MG745,MG740
MG746,MG740
MG747,MG740
I think a file approach would
work. But…
Are there better, faster ways of
handling this? Maybe an external database? Setting up some
sort of array in AB?
Please
help.
Thanks and
regards,
Dan.
