Data Mining Historic Stock Quotes in
Douglas A. Lyon · 2007
This paper describes how to extract historic stock quote data and display it. We show how to chart stock prices, using the web as a data source. The methodology for converting the web data source into internal data structures is based on using HTML as input. This type of screen scraping has become a popular means of recording data into programs. Simple string manipulation techniques are shown to be good enough for these types of well-formed data streams.
