RE: [amibroker] downloading information, AmiBroker Email List Archive

First I would try to do a proof of concept, then clean it up and make it more generic..adding a config file.

Just try to convert it. The class and methods are there.

For WebRequest, I think you can use the Inet.ocx to retrieve the HTML.

For regular expression, if there is any such library or com objects available to VB, use that..other wise, you can just do the parsing in using VB, though it would be much slower.

I have Office 2003…let me see if I can use the VBA editor convert some of it and you can fill in the rest and compile…give me an hour or so and I’ll get back to you…

Hi Anthony,

I created a DLL that does this, but as mentioned at the time, it was done with VS2005.NET, which means it is truly beta stuff. However I did post the source, see attached email, so if someone wants, the can use that as template to create a dll or script that all can use.

This can be improved upon greatly to "scrape" data from any site by using a config file to define how to scrape the data and how to retrieve it.

I was thinking about modifying to include a config file much like this:

URL = "" href="">http://finance.yahoo.com/q/ks?s=

DataItem = Float, (<\\s*td[^>]*>Float:.*?\\s*>.*?>)([\\d|\\.].*?[^a-zA-Z])([a-zA-Z]*)<"

DataItem = OutShares, (<\\s*td[^>]*>Shares Outstanding:.*?\\s*>.*?>)([\\d|\\.].*?[^a-zA-Z])([a-zA-Z]*)<"

This would tell me how to find and retrieve the float and outstanding shares from the URL specified and I could then access it by called Fundamentals.getData ("Float"). This code could also be converted to Jscript or VBScript I think.

I haven’t done any further work on this as I am currently in the process of setting up AB for use with eSignal (moving from DTN)…and I believe they provide fundamental data in their feeds.
