Project Title: Fred's StockRoom

##Authors Krin Yongvongphaiboon @aboutkrin Udit Bhansali @ubhansali

##Overview This project contains two parts, front-end and back-end. Front-end will be a HTML webpage that will take one or more US stock symbols from the user. The back-end will generate the live stock prices and data from Yahoo Finance then displays graphic quotes in rows and columns disposition. The front-end will display stock prices and graph/chart so the user can compare.

##Concepts Demonstrated Data modeling is used to define and analyze data requirements needed to support the market graph. Higher-order function is used for abstraction where functions produce other functions when calling URL-dispatch.

##External Technology and Libraries web-server/insta

jeeve/markets

##Favorite Scheme Expressions ####Krin In Racket, I'm impressed how easy it was to create a webpage. The following code demonstrate how you can create a unique link for the webpage and be able to call a function. The function will be the body of the link itself.

(define-values (start add-url)
  (dispatch-rules
   (("display-data") #:method "post"  display-data)
   (else get-first)))

####Udit This little snippet of code is to extract a single web form value from a set of bindings. This prevents previous inputs from being perpetuated and keeps each stock symbol isolated. Initially, we had trouble passing the id from the form as I had no idea how the Racket's internal procedures actually link the web pages, but since I am on the higher side of the abstraction, I don’t need to worry about it.

(define stock1-data (extract-binding/single 'stock1 (request-bindings req)))
(define stock2-data (extract-binding/single 'stock2 (request-bindings req)))
