Data wrappers, filters and scheduling daemon

on demand or daily produce a spreadsheet of the stocks about to go into earnings, the sentiment, put/call ratios, recent options activity, short ratios, etc. this spreadsheet will be the result of a series of data retrievals, the results of one driving the inputs of the next. this should be an os-independent application, able to run as a windows XP app as well as a linux process--perhaps using compiled python. It should use XML data wrappers (perhaps along the lines of XWRAP) to fetch pages from HTML web sites (some of which will require logon sequences) and return XML data sets. These data sets will be stored in a local database, with the source of the data, and the time retrieved for use in subsequent processing. The results of the queries should be visible both on an HTML page with sortable columns, as well as via a link to a dynamically generated .csv/.xls file from the same page. there should be a focus on architectural elegance and efficient processing at all levels--particularly with respect towards maximizing the use of resources once signed in to a site (minimizing page hits). ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform linux / windows xp -- application should run on either... producing local web pages that can be accessed on the file system or delivered via a local httpd.
