The goal of the exercise is to:

• Implement a website that allow user to "buy" and "sell" stock and the following functions:
• Complete the implementation of register, to enble the user to register for an account via a form.
• Complete the implementation of quote, to enable the user to look up a stock’s current price.

• Complete the implementation of index, to display an HTML table summarizing, for current logged in user, which stocks the user owns, the numbers of shares owned, the current price of each stock, and the total value of each holding (i.e., shares times price). Also display the user’s current cash balance along with a grand total (i.e., stocks’ total value plus cash).
• Complete the implementation of sell, to enable the user to sell shares of a stock (that he or she owns).
• Complete the implementation of history, to display an HTML table summarizing all of a user’s transactions ever, listing row by row each and every buy and every sell.

Apart from the function required and the built in function provided in this exercise, I added some of my own functions to the website:
