QuoteFilter is a companion to Xinvest and Xquote. You can use it to filter your emails messages and process the contents of some messages to retrieve stock quotes from them. The quote information can be stored in the files that Xinvest uses so that you'll automatically use recent information. Xquote serves a similar purpose, but it retrieves stock quote information from Internet servers.
